As a sailor I couldn't help but chuckle over your nervousness about whether the block would lift your generator. You could probably lift 3 with no problem. That block set would be great for all sorts of load handling jobs.
I used to have a barge on the rivers in Europe and YEP your'e 100% right . I still have a wooden block that I used myself years ago on my boat . I used it too lower barrels of engine oil into the engine room .
Being a sailor, I heartily recommend blocks and tackles such as from Nifty-lift. However, may I point out that you did not use a D-ring but a quik-link on the generator lift ring. Second, the line looks to me to be ultra-high-molecular-weight polyethylene, (Spectra, Dyneema, Amsteel) with a 1/4 in diameter line having a breaking strength of just over 6,000 lbs. The blocks or quik-link would probably give way before the line failed. Two more things: 1/4 inch line, as you felt, was way too small work with pulling 80 lbs. Yes, gloves were a good idea. (Better would have been blocks with three sheaves rather than two.) Finally, your choice of using a wooden handle to apply pull with was a good (and successful) idea but unsafe. Should your grip fail due to the line applying torque to your handle, the rotating handle's friction would be hard to deal with. The safer solution to that is the famous clove hitch, just as quick to use on the handle, but will not generate torque. (By the way, a 1/2 inch line has a breaking strength of over 23,000 lbs. Tough stuff, but expensive.)
I stumbled upon this video after watching SmarterEveryDay's video on 'snatch blocks'. I'm incredibly impressed by the one demonstrated here. I'd love to buy one! When you had the generator lifted and said you wasn't sure what you'd it for, the first thought that came to my mind was lifting something like the generator and backing a truck underneath it for easy loading and transport by a single person no less! Thanks for sharing this wonderfully designed product. Definitely going to look into purchasing one.
I hate to say it but I rather see this kind of product review from your subscribers things that they have built than to see the cheapest stuff from Amazon.
Why don't you start a channel like that, canvass some inventors to demonstrate their original inventions on your platform, oerhaos you & your inventors will become a sensation ☺!
Yea but this invention is a well build version of something already in use since ages. There are not that many good inventions. Is a quality hand made knife an invention?
Blocks are definitely still used on sailboats. A standard one mast (sloop) sailboat may have as many as four block and tackle set ups. They are needed to handle the high loads of the wind. There are modern devices that can take up the loads without block and tackle, but ultimately, the lines would not be able to handle it. When using a block and tackle not only is your effort minimized, so is the line's (or rope for you landlubbers).
I haven't heard of it called a clamcleat before, but I do see references online! I want to have a look at my Chapman's when I get home.. Learn something new everyday!
Davis Donnell yea I think that is more of an specific name fromm the company then a universal one but that's what I've been accustomed to and for the record I hate them so much they barely ever hold rope.
The applications of this are huge on a homestead rather than loading anything heavy into your truck with a ramp you can just put it in the air and back in your truck under it and then let it down.
This would be excellent for an avid camper to hoist food and gear up off the ground for safety I know when we go camping is usually a group of 8+ people and keeping everything in our lock box and hoisting it up 3 times a day or more usually takes 2 to 3 of us to do. With this, one person could do so quite easily. And the "Brake" he's using is called a clamcleat. They're made for sail boats. plenty strong enough for what that thing holds! Although a more robust rope for piece of mind would go a long way I think. But once you distribute the load over 4 lines it's super strong. Can't wait to talk my chief finical officer (The wife) Into this idea! Thanks for the excellent highlight of this American made product!
I don't think it'd really 'take longer'. If you're out in the woods you should be able to have a decent straight line to walk back and pull it up as you go.
You never cease to amaze me. If I'm researching crosscut saw sharpening, your'e the man. If I'm looking for body armor, night vision, firewood processing, irrigation, wood stoves, pulleys, comms, you name it, you're already posting about it! Is crazy how on target your areas of interest can be!
As Spelunkerd pointed out, the cord is known as UHMWPE or Dyneema. No stretch, can’t be flame sealed, 7/64 with a 1500 tensile. The block he gave you looked like a 4 or 5 part. Every time it crosses a pulley you get 1x. Crosses 4 times you 4x your strength but need to pull 4 feet to get 1 foot of travel.
"it's about the size of 550 cord so i don't know if this can lift my generator" well it's called 550 cord because it's rated for 550 pounds so i'm sure that this could lift your `200 pound generator
@@871copperhead Yea kinda of its rated for 550 pounds of static force minimum breaking strength. There is also a safe working load rating which is much lower to account for the amplification of force due to jolts on the line. There was also a different comment chain that mentioned the part of line leading from the fix point to the device holds 1/2 the weight of the load. So the generator might fall within the safe working load rating of what ever this is but its hard to say since all manufactures end up with different specs for their paracord.
Didn’t doubt this setup one bit. I’ve been around pulleys enough to know what are capable of and those that have never used one will probably be mind blown. Good looking setup. Thanks for sharing
I have been loving your videos. It's always fun to see things like this and even learn a few things. You seem to be quite knowledgeable and humble. I really respect and admire you.
Remember, the load is distributed across 6 lengths of cord - if it was 550 paracord, it would be very strong indeed. The cord he used is likely strong enough to hold anything that a strong person or two could lift with that block&tackle
The cord is called dyneema.if it is 4mm it will roughly a breaking strain of 2866.009lbs or 1,300kg and times that by 4 it will hold 11464.04lbs or 5200kg! it will never break! it is stronger than wire rope
Ordered one of these yesterday for snowmobiling, and extraction when stuck, which I try to avoid but happens on occasion, like riding solo, so this could be a life saver I am strong, however working smarter not harder is my new life motto so, had to get one. Cannot wait for it to arrive, looks like an amazingly well made tool
Slightly different I think, but I wish there were more interactive or hands on type stuff online. There’s a lot of videos showing the “theory” but not much actually showing real life scenarios
rolling pins make great pull handles. when you need to go higher step on the cord and roll it up the line with the handles. to use it for the actual pull handle grab the roller to prevent it from spinning.
he needs to change the title, a small block chevy block weighs 90 pounds at most. he needs to change it to it will lift a small blockchevy engine (fully assembled)
Chris Land Just tie a rope around it's hind ankles, throw said rope over a big branch, and hoist it up. Deer aren't all that heavy. Quit easy to hoist -- at least, in my experience.
Heinrich Von Kekelnazi deer no problem by yourself. Elk by yourself no way you will need some extra bodies or a hoist, come along, winch, or some sort of pulleys. Non of that will be as compact as this.
@wranglerstar The way it works: for each strand attached to the pulled or lifted side, you gain 1 multiplier. So with the block you have, you would have a multiplier of 4. Consequently, you would pull the rope 4 times as far to lift
Have been using these in technical rescue and rope climbing classes for decades. Just as small. And high enough quality to depend your, and whomever you've picked off a cliff, life on.
All these posters complaining about the cost forget that this is a much higher quality system, made with machined aluminum instead of pot metal, it is all enclosed rather than having wheels and bearings exposed where they often get dinged up and dirty, and it is a higher tensile strength cord. The comparisons given as a "cheaper and just as good" option were rated about 1 ton less and made somewhere overseas. If you support American Industry then you should be willing to pay a premium for a quality, locally made product. Just my 2¢
To save a few dollars, would you risk your life or heavy equipment by using a tool made with unknown quality control and cheaper materials? Cutting costs today can be much more expensive in the long run.
Definitely looks nicely made. I use a block and tackle when I'm camping in the back country to hoist my food bags beyond the reach of bears. I've had 2+ weeks worth of food for two hoisted before and 3 pullies made it just possible to hoist with both of our effort. With higher quality parts perhaps one could've hoisted, but it was a LOT of weight.
My grandfather used a full size come along (block & tackle) for removing stumps on our farm and lifting big block engines out of our truck or lifting up the tractor when it needed fixing.
Thank you. I’m trying to lift a heavy skirting table to the ceiling of my barn. (I own a sheep farm and hubby is usually working when I need to lift or lower this). Very helpful
I had to stop hunting because of my disability. If I killed a Deer I always had to call someone out to load it up. This would be great for lifting deer to load into the truck or back of atv etc
Shawn C. I'm in the same boat, but with an atv I can throw a rope over a branch and use the atv to pull up the deer. I bought a package deal with gambrel and small pulley from Hunter's Specialties (I think that's the brand ). The rope rotted before I could use it, so I use the gambrel and the atv with a rope over a limb now.
Never fails to amaze me how violent tree huggers like Goin Roxognor are .......... on the internet anyways ............ good thing they're cowards in the real world.
This was a really good video! I watched it from start to finish and I really enjoyed how you explained a bit about the block and tackle system and demonstrated its mechanical advantage. Subbed
Standard 550 cord(7 strands inside), there are some with 9- strands and 11- strands too. The old block and tackle 3 pulleys at each end. I can't remember if it make it 10% of the load. For easy all day work. For loading square bales in a barn loft.
I think a good addition to this piece of kit would be some kind of quick release pull handle that the pull cord feeds through. Something that can be pulled and locked pulled and locked as you hoyst. Then you wouldn't need to keep setting the brake and re-adjusting your grip.
I use this all the time up in the hills. Its always funny when i show up to pull someone out of the mud with 500ft of cable and 9 blocks. Btw im 19, 6,2 and weigh 198. So you see why people laugh. I've pulled 4 ton tractors out by myself and have earned quite the reputation for it. Can't ever go wrong with ancient technology thats been proven time and time again.
Same can be done with zero pulleys, so long as you have a truly non-stretching line. Chain works best, wire rope OK, too. Kevlar rope is the only rope that I know of that might work, and I'd guess that's what he has in this video. Heavy-duty 2" webbing or larger might work, too. If you link two things together with a completely taut line with no slack and no stretch, say the frame of a stuck car and the trunk of a large tree, then pull SIDEWAYS on the MIDDLE of the line, simple physics tells you that the force on the two ends is INFINITE, so one end or the other is going to bend, break, or move (or the line itself will stretch or break). Physics also tells us that the force drops off immediately and fairly quickly as soon as the line is anything but perfectly straight, so you can only get a few inches of motion per pull before you lose a lot of the mechanical advantage. When I freed a car this way, I had two helpers (the stuck people) with wooden chocks to put under the wheels, and every time the car shifted a few inches, they shifted the chocks. My buddy was at the tree, where we had maybe 3 turns of chain around the trunk to give him the frictional assist to hold it tight, and every time they shifted the chocks, he'd take up the slack around the tree, and I'd be ready to go again. Took probably 20 -25 pulls to get the car out, but we got pretty fast as a team, probably averaging under 1 minute per pull. I would estimate I maxed out at maybe 150 lbs of pulling force, and I was limited more by the potential damage to my gloved hand by the chain. This was done with no equipment other than wood chocks we scavenged from the woods around the road, two pairs of gloves, and 100' of sturdy chain.
Very true. Our ancient ancestors were so much more than we are. They had no vaccines, pollution or other body/mind contaminants. The ancients invented amazing things like: Writing, fire making, farming, hunting, metal working, roads, boats, science, glass, math, the bow and arrow, cloth, shoes, knots, carpentry, on and on.......And they did it from a pool of minds, (a few hundred million) with a fraction of the world population that we have today (7.4 Billion).
"What could go wrong"...at which point I realized the whole thing may fly apart, injuring millions. Instead, we get to watch someone who is honest, rational, reasonable, and overall interesting to watch. Thank you for another informative video, sir! Mike
I happened to be viewing several channels showing mechanical advantage examples with snatch-blocks, pulleys and rigs like you demonstrated. Thank you for the repetitive opportunities to aid me in learning!
Thanks for the introduction and review of this product. I'm getting into off-road and adventure style motorcycle riding, and I can see this product having a use in that scenario.
isn't mule tape, well tape. not cord?. anyhow a 1/8 inch braided spectra/dyneema line/cordage has a min strength of 2300lb. if that's too thin (cut your hands) 3/16 will do 5000lb (min). That should do..
Looks to me like amsteel, it's the stuff that whoopie slings for hammocks are made out of. The stuff has a high tensile strength and low stretch. It's great stuff and can be woven inside of itself and unlike paracord it does not have any guts inside which make it thinner. I've bought the rope and made my own continuous loops and ridgelines 7/64 amsteel rope has an average 1500 break strength. www.samsonrope.com/Pages/Product.aspx?ProductID=872
Going over a pulley puts more strain on a rope than most people expect. It's the difference in the inner and outer diameter of the rope as it goes over the wheel that causes this, and the smaller the pulley wheel is the worse this getts. For this reason it's been recommended that you don't use lines with kevlar core with a small diameter pulley. The Aramid fiber has extremely little give, making it tear itself apart when running over a small pulley. By making the ditch in the pulley square bottomed instead of round the line will be able to flatten itself to a degree and the difference in circumference will be smaller. Because of these kinds of problems cheaper lines with more stretch will actually last longer in a pulley system like this than if you were to go with the latest and greatest Aramid fiber line. By using a line that is designed to flatten itself to the wheel this effect is minimized and it will last longer and retain a higher percentage of it's strength. One problem that was mentioned is that something this thin will tend to cut into the hands, but in most cases wearing gloves will be enough. Remember that you will be pulling a lot less than the weight of what you are lifting.
@@iamaduckquack Then one day your standard equipment will either break, go missing, or be clearly unequipped to deal with the issue at hand. You and whoever you might be with will sit around, scratching their heads for a good 15 minutes before you remember that red thing in the glove box or buried underneath all your tools. It will take some fiddling around as you learn how to set it up, but when the moment comes, the tool will preform well! You, and whoever you might be with, will be in a great mood for the rest of the day and depending on the importance of the project, you might have a fun little story to tell over a beer or at Christmas.
Simple machines made with modern materials! I love my pulley system in my shop. From lifting elk and deer for skinning to holding pieces for painting or maneuvering large machinery to work/weld on. I even use mine to load or offload snowmobiles onto trailers by myself. I'd say it's a useful tool for people that do those sorts of things.
WOW!!!!!! What a great invention... and the price isn't that bad also (on their website). I'm going to buy a couple for emergencies and also buy some larger ones for every day use. They're also Veteran owned and I'll do whatever I can do to support them. Thanks for the great info! Amen Veteran
my guess is that it is some sort of Spectra rope, use it alot at work instead of chains. alot stronger than steel - so light that its fun to work with actually :D Slings made with Spectra fiber were used to lift 2.6 million-pound sections of the new San Francisco-Oakland Bay Bridge. buy som and test it, you'll be amazed!
There's not that much load being put on the rope due to the force multiplier effect of the block and tackle pulleys. Even a 1/4" polypropylene rope will have a minimum breaking load of 1125 lbs. Actual "working load" is some multiplier less than that depending upon the type of use -- maybe 1/2 for some uses, maybe 1/5 for other uses. For example, a working load for a horizontal pull where there no life is threatened might be 1/2 and a vertical lift where it might be lifted above people might be 1/5.
Would you be willing to show us how you set up your grandad's yale hoist? Is it connected to the rafters or some other weight bearing frame? I've always wondered how to instal those. Thanks for the consideration.
Once again, Wranglerstar to the rescue ! After all too much head scratching and all too little help. A entirely too heavy woodstove sits at tge bottom of the mountain. I stripped/disassembled as much weight off of it as I could without totally reducing it to a pile of parts. Then decided I would scan the tube for some means of getting this woodstove up 40 ft of mountain by myself. I tan across your vid and recalked a buddy giving me something very similar to what you are explaining here. So, here we go! Hope restored and the improvise/adapt/overcome mentality backnin place. Brother, over the years, I have been able to rely in your instructionals many times. I want to thank you for putting these videos up for others to work out a way to perform whatever their needs are. If they allowed 10 👍, you'd get 11 ! All the best to you and yours, Wulfy
Due to having 4 cords suspending the load, each cord only sees a quarter of the weight, but as you see the downside is that for every foot of lift you have to pull 4 feet of cord, that is the mechanical advantage - it is like a lever with a 4:1 advantage to lift a load you have to move the end of the lever a long way to lift the load a bit - you are trading distance for force. I have a similar small block and tackle with a 6:1 advantage - can lift 180lbs with a 30lb pull..
introducing a lower cost version...not anodized, no cleat, cloth sack...no case...going to pass on the savings to the customer...$ 79.95 but it's just as strong and internals are the same.
A little on the high side for the deluxe model just for an added locking break. But I’ve used it a number of times an it stays in the vehicle. When nothing else in a pinch would do but this. Has always turned out invaluable
The mechanical advantage you're using to lift the generator also applies to the chord so you don't have to be so worried about it breaking under the 80 lb force you're exerting on it. 4 strands of 1700 lb rated (or whatever it actually is) chord adds up to the claimed 6800 lb rating on the website if you can manage to pull on that string with nearly a ton of force without the block shattering into a million pieces.
Rope used is most likely, UHMWPE rope, either Dyneema or Spectra braided cord. UHMWPE is about 15x as strong as an equal weight of steel, and 8x lighter weight for an equal volume of steel, it's also hydrophobic so it will not absorb water. 1/8" diameter braided Dyneema has a tensile strength of 2500lbs and is slightly thinner than 550 paracord.
We used blocks a little bigger than that in the Army to pull a HMMWV out of the sand in training ... Blocks are amazing.. I use them all the time.. and a small block Chevrolet weighs approximately 475 to 500 pounds..
Buy a CMC Rescue Aztek. 8000lb min break strength. We use them all the time for rope rescue. 8mm rope 12 feet of travel. Also, in the video you are using a 4:1 mechanical advantage. If you flip the whole rig upside down you are using a 5:1 rig.
True that you get 5:1 if you pull upward, but then you have to BE pulling upward. Downward you need to use only your arms and shoulders. Upward you have to use your legs and back as well. If the load were at the limit of the tension I could manage, personally I would prefer to pull downward with an extra 25% rather than pull upward at the reduced tension. OTOH if you're a body builder who routinely jerks and curls more than your body weight, you might prefer the upward direction, because then the tension you could exert could be greater than your weight. Downward if you pulled that hard you'd just come off the ground
The concern here for me is how the weight is actually rated, especially coming from a 1-man show. Most hoist equipment is rated way below the actual tested breaking-strengh of the product, and the product is pushed to its breaking point thousands of times to test the minimum weight that causes a break. Hard to believe this guy has done that, but it's an impressive piece regardless.
Why wouldn't it? Mechanics and engineering don't just up and change or stop working because it's a different year 🤣 And it's "would have" not would of. Of isn't a verb. You can't of something. I would have gone becomes "I have gone" in simplified form. *NOT* "I would of gone" .... Which would become "I of gone" when simplified. I of gone isn't English. Neither is "would/could/should of" nobody taught you that. That's just pure ignorance and laziness.
Just looked at the website and HOLY COW!!!! That thing has a Max Weight of 6,800lbs!!!!!! Upon further looking at a close-up picture of the cordage, it appears that the cordage used is Dyneema or Amsteel. It's the same cordage used in synthetic winch rope and it's Extremely strong. 1/4" (dia.) Amsteel has a breaking strength of 7,700-8,600lbs and the same diameter Dyneema breaking strength is between 4,500-5,000lbs!!! .... I'll be a customer of his for sure!!
Well not quite that. The amount on tension per cord is where you get your real numbers. If you have 4 cord segments it is split 4 ways. So if you have a 2000 pound object you need to lift, you would need to have about 4 segments (if it is 600 pound rated rope) in order to lift that object.
I want one!!! I'm a sheet metal worker that welds, usually 10'-15' above the floor, climbing out of the scissor lift to perform my work. Being able to lift my MIG welder with that baby would be a treat!!!
STUDY RIGGING! You'll be glad you did. Study different types of winches, comealongs (industrial, not hardware store trash), ways of clamping sheet metal, etc. For example I use an eye bolt threaded into the adjuster bolt hole of a pair of visegrips to lift sheets and other material by rope or cable. I study professional riggers, arborists, and nautical rope users and equipment (I work alone and move a wide variety of material, machinery and vehicles).In your case the OSH compliant way would be to use "sheet metal lifting clamps" and any suitable wire cable or rope hoist. It being difficult to grab sheet metal I use visegrip sheet metal clamps as handles. There is a professional, SAFE, LOW LIABILITY way to do nearly every task so find out what tools of the (many) trade(s) work for you. Always compare pro gear to meme hobby toy gear. You can often save money especially by buying used. Your taxes paid for this outstanding rigging manual. Download and study it. www.marines.mil/Portals/1/MCRP%203-17.7J%20With%20Ch.%201%20z.pdf
I do Rope Access as profession. And these already exist. Cheaper with more strength. To inform you, not correct you. You said "for every pully you go through it doubles your pulling strength." This isn't correct. (Even people in my profession think this also. So your not alone here.) For every 'MOVING' pully, it doubles your lift per same applied force. A stationary pullys (like at the top where attached to structure) is merely a "REDIRECT". Only assisting in the direction (up or down) you pull force. The pully attached at the generator, if you notice, moves up with the load. Thus decreasing your applied force to lift gen. By half. But also doubles the distance you must pull through to get the same height. Imagine: Single rope from your hand up through a pully attached to beam. Down to the gen. Weighing say 100lbs. Needs 100lbs of force from your body cause pully only redirects direction of pull. Now, say your on a deck at the roof or somehow above the gen. Tie rope end to beam, run other end through pully attached to the gen. Back up to your hand up on that deck. Now you only need 50lbs to lift 100lbs cause the pully on the gen is moving up with the gen. Also his 1 pully is actually a double pully. So Sorry so long and conf. I just wanted the info there incase someone really wanted to know how mechanical advantage works.
Adam Whitfield it's good to learn, I am a level 2 SPRAT in Vancouver Canada , I am always learning so I can get my level 3 SPRAT and IRATA this winter. Any suggestions on material I can read?. Thanks
@@urbanmonkey48 thats good to hear brother!!! We always need good guys that have pride in such a valuable awesome market. And if u have your L1 and still want to continue a career in rope access, then your in luck. My advice to you is the advice i recieved as a L2 that i value today as some of the best words i coulda listened to. Most rope techs see the highest hill to stand on being the L3. It however is nothing more thsn a validation of basic knowledge for supervisors in this field. Yes the money can be fantastic. But it also can and is getting lower in some cases due to these cookey cutter L3s being popped out at such high numbers today. But if you value your career choice. If your proud of it. And if you wish to be more than a L3, then be listeing and absorbing now. You will learn some things needed to pass the 3. However what u will use on a daily basis as 1 and 2 is what u will need later the most when u are a 3. Everything you do, ask yourself why. And is that my best way to achieve that reason. And always be searching for new tricks and methods. Ive learned some amazing things from no rope access guys who watched their dad do something before. And always be teaching. U will always be around other crew members. And thsts my chance to not only assess their knowledge but to also go over some things and teach. Which most the time winds up im teaching more than that 1 person cause usually theres a guy that wont listen cause he know all.. But will silently learn there too. Lol. But my best reading is the sprat irata procedures. And to get even more knowledge check out youtube and google knots, chokers, slings, and especially mechanical advantage. Man im excited i have a brother out there who is excited about doing what i love. Oh and not sure the career path u wish. But NDT has afforded a VERY nice living. Keep going to classes and keep learning. U can reach low 50ph without an api or such. But all up to u. Ever have any questions shoot me an email brother. Later.
@@urbanmonkey48 P.S. if u look up 'Access Rules' out of Harvey Louisiana. And calm them. Either dwight or dwayne. (Brothers) they will be glad to help in any way u may need. And could offer even more data.
Reminds me of the Haltrac Mini Hoist which used to be made in the UK back in the 50's and 60's. I took an engine out my old Austin 7 Mini using one and a pair of ladders to make an "A frame" to lift from. Changed the clutch and put it all back. Even had the locking cam as an option on my one.
It's not even my generator and I was cringing. I get the mathematics behind it, and those are some very good looking blocks, but that cord really did look like a gutted 550 paracord. I will say that's a super handy little device, looks like some amazing craftsmanship.
"modern sailing ships" Sir, have you never sailed in your life? If no them I recommend it regardless. However, literally every single sailing ship has at least 3-4 of these on different locations. Decent sailing ships have at least 10 of them.
Used to use this when I did tower work. We called it a come a long and would use it with a pork chop to pull guy strand and wire. Very nice product That Albert has put together. Just a little pricey.
I have had something very similar for about 25 years, it is a three , four sheave block and tackle which gives a mechanical advantage of 7:1 , using correct rated line you can lift a weight 7 times the weight you pull down on. A very useful piece of kit!
It does not double the strength each time you go through a pulley. If it did, the ratios would be 1:1, 2:1, 4:1, 8:1, 16:1, 32:1, 64:1, 128:1, 256:1, 512:1, 1024:1, 2048:1, 4096:1, and so on. But it actually goes 1:1, 2:1, 3:1, 4:1, 5:1 each time you add a pulley.
Having gotten to the stage where I do use a block and tackle often, I can see the usefulness of this smaller rig......but with expensive/delicate items it would take me a hell of a long time to actually learn to trust such thin cord.
I believe the Liberty Ships were being turned out 1 per week. That's a pretty awesome rate. since they were 300~400 foot ships. But 1 per day . . . no way.
lingcodnine Yes they actually did. Look them up. They were not only famous for how quickly they were produced, they are also famous for splitting in half and sinking overnight after being loaded up. It gave rise to modern fracture mechanics. Previous ships had riveted hulls, liberty ships were all welded.
Produced from 1941 thru 1945. 5 years = 1826 days (added 1 day for leap year. Take that, yammerheads). 18 shipyards made 2710 of these ships. So...yeah, more than one per day (just not 2 per day.)
it doenst matter how many shipyards were involved...they were still making more than a ship a day (on average) WE ARE TALKING ABOUT TOTAL NUMBER OF SHIPS BUILT PER DAY not total ships build per day PER SHIPYARD *facepalm* yammerhead. nobody thinks a single shipyard can knock out a ship in a day
I have a block and tackle about the same size. I've used it to lift a motorcycle up to remove the rear end. I've replaced and removed a washer, dryer and water heater tank into my basement of my farmhouse. It's so easy ! I do the pulling and my wife just guides the equipment up or down the stairs.

Kudos to Cody!
I wouldn't expect any less. Project farm and wranglerstar are the only channels I go to for tool testing and honest tests or opinions.
As a sailor I couldn't help but chuckle over your nervousness about whether the block would lift your generator. You could probably lift 3 with no problem. That block set would be great for all sorts of load handling jobs.
I used to have a barge on the rivers in Europe and YEP your'e 100% right . I still have a wooden block that I used myself years ago on my boat . I used it too lower barrels of engine oil into the engine room .
I think it was the brake that gave him pause.
@@SettleNow brake (cleat) will hold no problem if made of the right plastic. The cleat only has to hold 1/5th the weight of the load.
Yip.
Is this applicable to logging using a portable winch
Being a sailor, I heartily recommend blocks and tackles such as from Nifty-lift. However, may I point out that you did not use a D-ring but a quik-link on the generator lift ring. Second, the line looks to me to be ultra-high-molecular-weight polyethylene, (Spectra, Dyneema, Amsteel) with a 1/4 in diameter line having a breaking strength of just over 6,000 lbs. The blocks or quik-link would probably give way before the line failed. Two more things: 1/4 inch line, as you felt, was way too small work with pulling 80 lbs. Yes, gloves were a good idea. (Better would have been blocks with three sheaves rather than two.) Finally, your choice of using a wooden handle to apply pull with was a good (and successful) idea but unsafe. Should your grip fail due to the line applying torque to your handle, the rotating handle's friction would be hard to deal with. The safer solution to that is the famous clove hitch, just as quick to use on the handle, but will not generate torque. (By the way, a 1/2 inch line has a breaking strength of over 23,000 lbs. Tough stuff, but expensive.)
Yes indeed. The clove hitch causes no torque on the handle 😉
I stumbled upon this video after watching SmarterEveryDay's video on 'snatch blocks'. I'm incredibly impressed by the one demonstrated here. I'd love to buy one!
When you had the generator lifted and said you wasn't sure what you'd it for, the first thought that came to my mind was lifting something like the generator and backing a truck underneath it for easy loading and transport by a single person no less! Thanks for sharing this wonderfully designed product. Definitely going to look into purchasing one.

Why don't you start a channel like that, canvass some inventors to demonstrate their original inventions on your platform, oerhaos you & your inventors will become a sensation ☺!
Why do you hate to say it ?
dont think theres a channel for that... it would be amazing.
Yea but this invention is a well build version of something already in use since ages. There are not that many good inventions. Is a quality hand made knife an invention?
Blocks are definitely still used on sailboats. A standard one mast (sloop) sailboat may have as many as four block and tackle set ups. They are needed to handle the high loads of the wind. There are modern devices that can take up the loads without block and tackle, but ultimately, the lines would not be able to handle it. When using a block and tackle not only is your effort minimized, so is the line's (or rope for you landlubbers).
Oh, and the brake, is actually called a jam cleat, or a v cleat.
Davis Donnell sailors call it clamcleat and true about sailing
I haven't heard of it called a clamcleat before, but I do see references online! I want to have a look at my Chapman's when I get home.. Learn something new everyday!
Davis Donnell yea I think that is more of an specific name fromm the company then a universal one but that's what I've been accustomed to and for the record I hate them so much they barely ever hold rope.
not a Clamcleat, A cam cleat.
Thanks!
A 350 chevy fully assembled is going weigh in around 550 to 575lbs. No where near what was stated here.
The applications of this are huge on a homestead rather than loading anything heavy into your truck with a ramp you can just put it in the air and back in your truck under it and then let it down.
Are you speaking english?
Ya just need a Skyhook in the right place
@@brw3079 or appropriate structural beam and sling. Like the roof rafter or purlin under a shed.
Or, if the item you're loading has wheels (like a four wheeler), you can use this as a winch to pull it forward.
This would be excellent for an avid camper to hoist food and gear up off the ground for safety I know when we go camping is usually a group of 8+ people and keeping everything in our lock box and hoisting it up 3 times a day or more usually takes 2 to 3 of us to do. With this, one person could do so quite easily. And the "Brake" he's using is called a clamcleat. They're made for sail boats. plenty strong enough for what that thing holds! Although a more robust rope for piece of mind would go a long way I think. But once you distribute the load over 4 lines it's super strong. Can't wait to talk my chief finical officer (The wife) Into this idea! Thanks for the excellent highlight of this American made product!
It would take longer though as you have to pull a lot of cord through the 4 pulleys.
Yes, longer, but for only needing one person at camp (Even the young teens) it can be hoisted up and down for food and supplies by anyone.
I don't think it'd really 'take longer'. If you're out in the woods you should be able to have a decent straight line to walk back and pull it up as you go.
That cord is more than enough to do the job. thin =/= weak, that's not how materials work.

You never cease to amaze me. If I'm researching crosscut saw sharpening, your'e the man. If I'm looking for body armor, night vision, firewood processing, irrigation, wood stoves, pulleys, comms, you name it, you're already posting about it! Is crazy how on target your areas of interest can be!

Why the hell you got a couch in the kitchen?
you may need some nail clippers also ...LOL
🤣🤣
As Spelunkerd pointed out, the cord is known as UHMWPE or Dyneema. No stretch, can’t be flame sealed, 7/64 with a 1500 tensile. The block he gave you looked like a 4 or 5 part. Every time it crosses a pulley you get 1x. Crosses 4 times you 4x your strength but need to pull 4 feet to get 1 foot of travel.
That is a great little device, that I can see a lot of uses for, including hanging game in the shed, and general use in the basement shop.
That's a good idea but I wanted to read the reply's first.
"it's about the size of 550 cord so i don't know if this can lift my generator" well it's called 550 cord because it's rated for 550 pounds so i'm sure that this could lift your `200 pound generator
550 cord is rated for 120lbs safe working load. This is a different material
@boxfoxreyes9950 no, true 550 cord is absolutely rated for 550 pounds of force
@@871copperhead Yea kinda of its rated for 550 pounds of static force minimum breaking strength. There is also a safe working load rating which is much lower to account for the amplification of force due to jolts on the line. There was also a different comment chain that mentioned the part of line leading from the fix point to the device holds 1/2 the weight of the load. So the generator might fall within the safe working load rating of what ever this is but its hard to say since all manufactures end up with different specs for their paracord.
Didn’t doubt this setup one bit. I’ve been around pulleys enough to know what are capable of and those that have never used one will probably be mind blown. Good looking setup. Thanks for sharing
I have been loving your videos. It's always fun to see things like this and even learn a few things. You seem to be quite knowledgeable and humble. I really respect and admire you.
the clear windows on the back of your shop are looking awesome!
Remember, the load is distributed across 6 lengths of cord - if it was 550 paracord, it would be very strong indeed. The cord he used is likely strong enough to hold anything that a strong person or two could lift with that block&tackle
I'm only seeing 4 .... maybe 5 if you count the pulling cord, but that's not really where your load distribution happens
That's because there's only 4, and I need glasses haha
The cord is called dyneema.if it is 4mm it will roughly a breaking strain of 2866.009lbs or 1,300kg and times that by 4 it will hold 11464.04lbs or 5200kg! it will never break! it is stronger than wire rope
Aidan33Gaming no it's not, that's Vectran.
2866.009lbs = "roughly"
This just in - Block and tackle works! Who knew!

Cannot wait for it to arrive, looks like an amazingly well made tool
I have always said, "I'm not afraid to work hard, but I'd rather work smart!"
Destin from Smarter Every Day gives a really good presentation of these. "snatch blocks"
Slightly different I think, but I wish there were more interactive or hands on type stuff online.
There’s a lot of videos showing the “theory” but not much actually showing real life scenarios
rolling pins make great pull handles. when you need to go higher step on the cord and roll it up the line with the handles. to use it for the actual pull handle grab the roller to prevent it from spinning.

A small block chevy, depending on how many cast parts, weighs 550-725lbs. Most modern produced ones from jegs, summit etc are under 650.
Hilariously, the 70bhp 4-cylinder in my Land Rover weighs the same, 550lbs or so. They put some iron in that thing!
And small block fords are anywhere from 550 to 675 if i remember right

sbc block weighs like 150lbs.
it would be great for a hunting situation. example field dressing a deer or elk.
150.00 deer lift
Chris Land Just tie a rope around it's hind ankles, throw said rope over a big branch, and hoist it up. Deer aren't all that heavy. Quit easy to hoist -- at least, in my experience.
Heinrich Von Kekelnazi deer no problem by yourself. Elk by yourself no way you will need some extra bodies or a hoist, come along, winch, or some sort of pulleys. Non of that will be as compact as this.
White tail, sure thing. Elk? Well they are a deer but I bet they weigh more than you do.
Lol Heinrich. try that with a moose. And do it without destroying the tree branch.
@wranglerstar The way it works: for each strand attached to the pulled or lifted side, you gain 1 multiplier. So with the block you have, you would have a multiplier of 4. Consequently, you would pull the rope 4 times as far to lift
Have been using these in technical rescue and rope climbing classes for decades. Just as small. And high enough quality to depend your, and whomever you've picked off a cliff, life on.
All these posters complaining about the cost forget that this is a much higher quality system, made with machined aluminum instead of pot metal, it is all enclosed rather than having wheels and bearings exposed where they often get dinged up and dirty, and it is a higher tensile strength cord. The comparisons given as a "cheaper and just as good" option were rated about 1 ton less and made somewhere overseas. If you support American Industry then you should be willing to pay a premium for a quality, locally made product. Just my 2¢
thanks for the insight you can appreciate good quality...the ones that post "it's too much money" maybe they work for free
To save a few dollars, would you risk your life or heavy equipment by using a tool made with unknown quality control and cheaper materials? Cutting costs today can be much more expensive in the long run.
@@pingumcping He's not entitled, he's a patriot.
I agree. lets support our hometown economy first.
Definitely looks nicely made. I use a block and tackle when I'm camping in the back country to hoist my food bags beyond the reach of bears. I've had 2+ weeks worth of food for two hoisted before and 3 pullies made it just possible to hoist with both of our effort. With higher quality parts perhaps one could've hoisted, but it was a LOT of weight.

I had to stop hunting because of my disability. If I killed a Deer I always had to call someone out to load it up. This would be great for lifting deer to load into the truck or back of atv etc
Shawn C. This was my first thought too. Great little tool for hunters!
Shawn C. I'm in the same boat, but with an atv I can throw a rope over a branch and use the atv to pull up the deer. I bought a package deal with gambrel and small pulley from Hunter's Specialties (I think that's the brand ). The rope rotted before I could use it, so I use the gambrel and the atv with a rope over a limb now.

Your grandad’s hoist will last for generations to come! Great review.
This was a really good video! I watched it from start to finish and I really enjoyed how you explained a bit about the block and tackle system and demonstrated its mechanical advantage. Subbed
Standard 550 cord(7 strands inside), there are some with 9- strands and 11- strands too. The old block and tackle 3 pulleys at each end. I can't remember if it make it 10% of the load. For easy all day work. For loading square bales in a barn loft.
I think a good addition to this piece of kit would be some kind of quick release pull handle that the pull cord feeds through. Something that can be pulled and locked pulled and locked as you hoyst. Then you wouldn't need to keep setting the brake and re-adjusting your grip.
I use this all the time up in the hills. Its always funny when i show up to pull someone out of the mud with 500ft of cable and 9 blocks. Btw im 19, 6,2 and weigh 198. So you see why people laugh. I've pulled 4 ton tractors out by myself and have earned quite the reputation for it. Can't ever go wrong with ancient technology thats been proven time and time again.
Exactly, brother!
I don't k ow if you'll see this but you've gotta upload a video of that
Same can be done with zero pulleys, so long as you have a truly non-stretching line. Chain works best, wire rope OK, too. Kevlar rope is the only rope that I know of that might work, and I'd guess that's what he has in this video. Heavy-duty 2" webbing or larger might work, too.
If you link two things together with a completely taut line with no slack and no stretch, say the frame of a stuck car and the trunk of a large tree, then pull SIDEWAYS on the MIDDLE of the line, simple physics tells you that the force on the two ends is INFINITE, so one end or the other is going to bend, break, or move (or the line itself will stretch or break). Physics also tells us that the force drops off immediately and fairly quickly as soon as the line is anything but perfectly straight, so you can only get a few inches of motion per pull before you lose a lot of the mechanical advantage. When I freed a car this way, I had two helpers (the stuck people) with wooden chocks to put under the wheels, and every time the car shifted a few inches, they shifted the chocks. My buddy was at the tree, where we had maybe 3 turns of chain around the trunk to give him the frictional assist to hold it tight, and every time they shifted the chocks, he'd take up the slack around the tree, and I'd be ready to go again. Took probably 20 -25 pulls to get the car out, but we got pretty fast as a team, probably averaging under 1 minute per pull. I would estimate I maxed out at maybe 150 lbs of pulling force, and I was limited more by the potential damage to my gloved hand by the chain. This was done with no equipment other than wood chocks we scavenged from the woods around the road, two pairs of gloves, and 100' of sturdy chain.
Very true. Our ancient ancestors were so much more than we are. They had no vaccines, pollution or other body/mind contaminants. The ancients invented amazing things like: Writing, fire making, farming, hunting, metal working, roads, boats, science, glass, math, the bow and arrow, cloth, shoes, knots, carpentry, on and on.......And they did it from a pool of minds, (a few hundred million) with a fraction of the world population that we have today (7.4 Billion).
They also died in their 30's
"What could go wrong"...at which point I realized the whole thing may fly apart, injuring millions. Instead, we get to watch someone who is honest, rational, reasonable, and overall interesting to watch. Thank you for another informative video, sir! Mike
I happened to be viewing several channels showing mechanical advantage examples with snatch-blocks, pulleys and rigs like you demonstrated. Thank you for the repetitive opportunities to aid me in learning!
The small block and tackle that was sent to you is fabulous. I’m sure you will find many opportunities to use it. Albert did a great 👍 job.
Thanks for the introduction and review of this product. I'm getting into off-road and adventure style motorcycle riding, and I can see this product having a use in that scenario.
Another adventure rider! How was last season?
The line on that looks a bit like 'mule tape'. The mule tape I have is rated at 1800lbs.
Was hoping someone would mention Mule Tape. Incredible stuff!
Mark. The only thing that makes me unsure if it is mule tape , is the size of the line. It seems about half the width of the mule tape I have.
isn't mule tape, well tape. not cord?.
anyhow a 1/8 inch braided spectra/dyneema line/cordage has a min strength of 2300lb.
if that's too thin (cut your hands) 3/16 will do 5000lb (min).
That should do..
Looks to me like amsteel, it's the stuff that whoopie slings for hammocks are made out of. The stuff has a high tensile strength and low stretch. It's great stuff and can be woven inside of itself and unlike paracord it does not have any guts inside which make it thinner. I've bought the rope and made my own continuous loops and ridgelines 7/64 amsteel rope has an average 1500 break strength. www.samsonrope.com/Pages/Product.aspx?ProductID=872
Going over a pulley puts more strain on a rope than most people expect. It's the difference in the inner and outer diameter of the rope as it goes over the wheel that causes this, and the smaller the pulley wheel is the worse this getts. For this reason it's been recommended that you don't use lines with kevlar core with a small diameter pulley. The Aramid fiber has extremely little give, making it tear itself apart when running over a small pulley. By making the ditch in the pulley square bottomed instead of round the line will be able to flatten itself to a degree and the difference in circumference will be smaller.
Because of these kinds of problems cheaper lines with more stretch will actually last longer in a pulley system like this than if you were to go with the latest and greatest Aramid fiber line.
By using a line that is designed to flatten itself to the wheel this effect is minimized and it will last longer and retain a higher percentage of it's strength. One problem that was mentioned is that something this thin will tend to cut into the hands, but in most cases wearing gloves will be enough. Remember that you will be pulling a lot less than the weight of what you are lifting.

This looks like something I can use to hoist bags of groceries up my 2nd story deck entrance. Muscle mass not what it used to be.
my guess is that it is some sort of Spectra rope, use it alot at work instead of chains. alot stronger than steel - so light that its fun to work with actually :D Slings made with Spectra fiber were used to lift 2.6 million-pound sections of the new San Francisco-Oakland Bay Bridge.
buy som and test it, you'll be amazed!
I was going to say the same so kudos to you.
Mr. Sandnes ...I will sir, and thanks...ďà wòöķįęè
This explains the pricetag. Paying for the tech.
There's not that much load being put on the rope due to the force multiplier effect of the block and tackle pulleys. Even a 1/4" polypropylene rope will have a minimum breaking load of 1125 lbs. Actual "working load" is some multiplier less than that depending upon the type of use -- maybe 1/2 for some uses, maybe 1/5 for other uses. For example, a working load for a horizontal pull where there no life is threatened might be 1/2 and a vertical lift where it might be lifted above people might be 1/5.
It's dynema rope. Now used alot on car winches. And used as soft shackles instead of metal D shackles. 12mm (1/2 inch) can take 14 metric ton's.
Remember what Scotty said. "If my grandmother had wheels she'd be a wagon." They probably meant an engine for a gas motor scooter.

After all too much head scratching and all too little help. A entirely too heavy woodstove sits at tge bottom of the mountain. I stripped/disassembled as much weight off of it as I could without totally reducing it to a pile of parts. Then decided I would scan the tube for some means of getting this woodstove up 40 ft of mountain by myself. I tan across your vid and recalked a buddy giving me something very similar to what you are explaining here.

Due to having 4 cords suspending the load, each cord only sees a quarter of the weight, but as you see the downside is that for every foot of lift you have to pull 4 feet of cord, that is the mechanical advantage - it is like a lever with a 4:1 advantage to lift a load you have to move the end of the lever a long way to lift the load a bit - you are trading distance for force. I have a similar small block and tackle with a 6:1 advantage - can lift 180lbs with a 30lb pull..
Cool little set there. Pretty dang expensive to buy but seems like it might last a generation or two...or three..or...
introducing a lower cost version...not anodized, no cleat, cloth sack...no case...going to pass on the savings to the customer...$ 79.95 but it's just as strong and internals are the same.
Darn it! The price is great BUT the CAM LOCK (GONE in this new version) is what made it really useful.
Yeah, that feature is in the Deluxe edition, for an approximate additional 50$. No way a small piece of plastic can cost that much.
A little on the high side for the deluxe model just for an added locking break. But I’ve used it a number of times an it stays in the vehicle. When nothing else in a pinch would do but this. Has always turned out invaluable

The mechanical advantage you're using to lift the generator also applies to the chord so you don't have to be so worried about it breaking under the 80 lb force you're exerting on it. 4 strands of 1700 lb rated (or whatever it actually is) chord adds up to the claimed 6800 lb rating on the website if you can manage to pull on that string with nearly a ton of force without the block shattering into a million pieces.
It actually can lift an engine into a truck, Matt from Demolition Ranch did it with that exact same thing on his second channel Off The Ranch.
Rope used is most likely, UHMWPE rope, either Dyneema or Spectra braided cord. UHMWPE is about 15x as strong as an equal weight of steel, and 8x lighter weight for an equal volume of steel, it's also hydrophobic so it will not absorb water. 1/8" diameter braided Dyneema has a tensile strength of 2500lbs and is slightly thinner than 550 paracord.
We used blocks a little bigger than that in the Army to pull a HMMWV out of the sand in training ... Blocks are amazing.. I use them all the time.. and a small block Chevrolet weighs approximately 475 to 500 pounds..
Power doubles each time the line passes through a moving pulley (lower set).
Stationary pulleys (upper set) don’t figure into the formula. 👍
Buy a CMC Rescue Aztek. 8000lb min break strength. We use them all the time for rope rescue. 8mm rope 12 feet of travel.
Also, in the video you are using a 4:1 mechanical advantage. If you flip the whole rig upside down you are using a 5:1 rig.
True that you get 5:1 if you pull upward, but then you have to BE pulling upward. Downward you need to use only your arms and shoulders. Upward you have to use your legs and back as well. If the load were at the limit of the tension I could manage, personally I would prefer to pull downward with an extra 25% rather than pull upward at the reduced tension.
OTOH if you're a body builder who routinely jerks and curls more than your body weight, you might prefer the upward direction, because then the tension you could exert could be greater than your weight. Downward if you pulled that hard you'd just come off the ground
The concern here for me is how the weight is actually rated, especially coming from a 1-man show.
Most hoist equipment is rated way below the actual tested breaking-strengh of the product, and the product is pushed to its breaking point thousands of times to test the minimum weight that causes a break. Hard to believe this guy has done that, but it's an impressive piece regardless.
This would work good as a mini haul system for rope access work !
Great videos! Keep up the good work. I really appreciate these and share with my 3 sons. PS - block and tackle gear is always cool!

@@dahooool Hey, we WERE having fun until "Mr. Professor" here butted in, killjoy
Just looked at the website and HOLY COW!!!! That thing has a Max Weight of 6,800lbs!!!!!! Upon further looking at a close-up picture of the cordage, it appears that the cordage used is Dyneema or Amsteel. It's the same cordage used in synthetic winch rope and it's Extremely strong. 1/4" (dia.) Amsteel has a breaking strength of 7,700-8,600lbs and the same diameter Dyneema breaking strength is between 4,500-5,000lbs!!! .... I'll be a customer of his for sure!!
TheVABigDog where on the website do u see any numbers that add up to 6800. All I see is 1700 with a 700 safe working load
you my friend are soo wrong. do youre homework before misleading people .....
1700 max safe workload 700 not no 6800 lbs
Safe working load with rope is 1/10 the breaking strength. So the rope may be amsteel. Except I've only seen blue colored amsteel.
Well not quite that. The amount on tension per cord is where you get your real numbers. If you have 4 cord segments it is split 4 ways. So if you have a 2000 pound object you need to lift, you would need to have about 4 segments (if it is 600 pound rated rope) in order to lift that object.
I want one!!! I'm a sheet metal worker that welds, usually 10'-15' above the floor, climbing out of the scissor lift to perform my work. Being able to lift my MIG welder with that baby would be a treat!!!
Joel Brown then why not keep your mig in the scissor lift and just pull your leads out of the lift? Lmao
STUDY RIGGING! You'll be glad you did. Study different types of winches, comealongs (industrial, not hardware store trash), ways of clamping sheet metal, etc. For example I use an eye bolt threaded into the adjuster bolt hole of a pair of visegrips to lift sheets and other material by rope or cable. I study professional riggers, arborists, and nautical rope users and equipment (I work alone and move a wide variety of material, machinery and vehicles).In your case the OSH compliant way would be to use "sheet metal lifting clamps" and any suitable wire cable or rope hoist. It being difficult to grab sheet metal I use visegrip sheet metal clamps as handles.
There is a professional, SAFE, LOW LIABILITY way to do nearly every task so find out what tools of the (many) trade(s) work for you. Always compare pro gear to meme hobby toy gear. You can often save money especially by buying used. Your taxes paid for this outstanding rigging manual. Download and study it. www.marines.mil/Portals/1/MCRP%203-17.7J%20With%20Ch.%201%20z.pdf
@@obfuscated3090 Thanks Man!
All good and informative stuff on here fella,,Respect all the way from England ✊✊✊✊🇬🇧
I need one of these for my backwoods ATV/snow machine kit to make sure I can pull myself out of holes or flip machines
Found you today and I'm already 5 videos in.
The block and tackle dates back to Archimedes.
dates before him.
I do Rope Access as profession. And these already exist. Cheaper with more strength.
To inform you, not correct you. You said "for every pully you go through it doubles your pulling strength."
This isn't correct. (Even people in my profession think this also. So your not alone here.) For every 'MOVING' pully, it doubles your lift per same applied force.
A stationary pullys (like at the top where attached to structure) is merely a "REDIRECT". Only assisting in the direction (up or down) you pull force.
The pully attached at the generator, if you notice, moves up with the load. Thus decreasing your applied force to lift gen. By half. But also doubles the distance you must pull through to get the same height.
Imagine:
Single rope from your hand up through a pully attached to beam. Down to the gen. Weighing say 100lbs. Needs 100lbs of force from your body cause pully only redirects direction of pull. Now, say your on a deck at the roof or somehow above the gen. Tie rope end to beam, run other end through pully attached to the gen. Back up to your hand up on that deck. Now you only need 50lbs to lift 100lbs cause the pully on the gen is moving up with the gen. Also his 1 pully is actually a double pully. So
Sorry so long and conf. I just wanted the info there incase someone really wanted to know how mechanical advantage works.
Adam Whitfield it's good to learn, I am a level 2 SPRAT in Vancouver Canada , I am always learning so I can get my level 3 SPRAT and IRATA this winter. Any suggestions on material I can read?. Thanks
@@urbanmonkey48 thats good to hear brother!!! We always need good guys that have pride in such a valuable awesome market. And if u have your L1 and still want to continue a career in rope access, then your in luck. My advice to you is the advice i recieved as a L2 that i value today as some of the best words i coulda listened to.
Most rope techs see the highest hill to stand on being the L3. It however is nothing more thsn a validation of basic knowledge for supervisors in this field. Yes the money can be fantastic. But it also can and is getting lower in some cases due to these cookey cutter L3s being popped out at such high numbers today. But if you value your career choice. If your proud of it. And if you wish to be more than a L3, then be listeing and absorbing now. You will learn some things needed to pass the 3. However what u will use on a daily basis as 1 and 2 is what u will need later the most when u are a 3. Everything you do, ask yourself why. And is that my best way to achieve that reason. And always be searching for new tricks and methods. Ive learned some amazing things from no rope access guys who watched their dad do something before. And always be teaching. U will always be around other crew members. And thsts my chance to not only assess their knowledge but to also go over some things and teach. Which most the time winds up im teaching more than that 1 person cause usually theres a guy that wont listen cause he know all.. But will silently learn there too. Lol.
But my best reading is the sprat irata procedures. And to get even more knowledge check out youtube and google knots, chokers, slings, and especially mechanical advantage.
Man im excited i have a brother out there who is excited about doing what i love. Oh and not sure the career path u wish. But NDT has afforded a VERY nice living. Keep going to classes and keep learning. U can reach low 50ph without an api or such. But all up to u.
Ever have any questions shoot me an email brother. Later.
@@urbanmonkey48 P.S. if u look up 'Access Rules' out of Harvey Louisiana. And calm them. Either dwight or dwayne. (Brothers) they will be glad to help in any way u may need. And could offer even more data.
1:4 pulley. Not rocket science.
Reminds me of the Haltrac Mini Hoist which used to be made in the UK back in the 50's and 60's. I took an engine out my old Austin 7 Mini using one and a pair of ladders to make an "A frame" to lift from. Changed the clutch and put it all back. Even had the locking cam as an option on my one.
It's not even my generator and I was cringing. I get the mathematics behind it, and those are some very good looking blocks, but that cord really did look like a gutted 550 paracord. I will say that's a super handy little device, looks like some amazing craftsmanship.
"modern sailing ships"
Sir, have you never sailed in your life? If no them I recommend it regardless.
However, literally every single sailing ship has at least 3-4 of these on different locations.
Decent sailing ships have at least 10 of them.

Well you’re actually wrong, there is a distinction between the two
@@jamesdowney723 those that have stink boats.
Use'd to tighten fencing wire. Neat little thing. Lots of uses.
You should definitely test this to destruction, really put it through its paces and see what it can handle.
We use a very similar item called a fence stretcher, for pulling fence wire tight,it's been around for ages
Used to use this when I did tower work. We called it a come a long and would use it with a pork chop to pull guy strand and wire. Very nice product That Albert has put together. Just a little pricey.
I feel like I've been watching this for a week
Ha ha ha
COOL !!!
Alexander Forestlamp? That is a unique name if I've ever heard one!
im going to buy this.
your rich !!!! $150.
Half the people posting here have a knife that costs that much not that I'm claiming that was a smart move.
I have had something very similar for about 25 years, it is a three , four sheave block and tackle which gives a mechanical advantage of 7:1 , using correct rated line you can lift a weight 7 times the weight you pull down on. A very useful piece of kit!
It does not double the strength each time you go through a pulley. If it did, the ratios would be 1:1, 2:1, 4:1, 8:1, 16:1, 32:1, 64:1, 128:1, 256:1, 512:1, 1024:1, 2048:1, 4096:1, and so on. But it actually goes 1:1, 2:1, 3:1, 4:1, 5:1 each time you add a pulley.

Richard Maunder Since when did the 'USA' become the pinnacle of quality?
Tom Green never did, some people just don't want it to be true
Its the pinnacle of labor costs.
They sell this device for about a 1/3 of the cost at every sportsmans type store for just that purpose.
Having gotten to the stage where I do use a block and tackle often, I can see the usefulness of this smaller rig......but with expensive/delicate items it would take me a hell of a long time to actually learn to trust such thin cord.
I believe the Liberty Ships were being turned out 1 per week. That's a pretty awesome rate. since they were 300~400 foot ships. But 1 per day . . . no way.
lingcodnine Yes they actually did. Look them up. They were not only famous for how quickly they were produced, they are also famous for splitting in half and sinking overnight after being loaded up. It gave rise to modern fracture mechanics. Previous ships had riveted hulls, liberty ships were all welded.
Produced from 1941 thru 1945. 5 years = 1826 days (added 1 day for leap year. Take that, yammerheads). 18 shipyards made 2710 of these ships. So...yeah, more than one per day (just not 2 per day.)
1826 days ... 2710 ships... thats very clearly more than 1 ship for every 12 days
yammerhead
it doenst matter how many shipyards were involved...they were still making more than a ship a day (on average)
WE ARE TALKING ABOUT TOTAL NUMBER OF SHIPS BUILT PER DAY
not total ships build per day PER SHIPYARD
*facepalm* yammerhead. nobody thinks a single shipyard can knock out a ship in a day
I have a block and tackle about the same size. I've used it to lift a motorcycle up to remove the rear end.
I've replaced and removed a washer, dryer and water heater tank into my basement of my farmhouse. It's so easy !
I do the pulling and my wife just guides the equipment up or down the stairs.
Pulleys are great, thanks for all you do for us! 👍
