- How strong are jack stands? How much safety pin adds to the strength? We are going to find out today by using our 150 ton hydraulic press and 150 ton force sensor. Not unaccurate pressure meter like on the older video

Make the ultimate fruit juicer. It'll have to be made of something that won't contaminate the juice so you can drink it.
Not gunna lie, watching this made me feel a lot better about jack stands and working under my car while using them. Good stuff!
Yeah, there's no way those would slip... Unless....
@@MightyGimp hear it often enough on local news- it is no accident we hear the phrase "wise old man"
You would think that everyone would use jack stands when working under a car, but I still see some that don’t, ever. Accidents waiting to happen.
@@MightyGimp yeah 2 jack stands, floor jack to take off some load, and tires for worst case scenario - better look stupid than die stupid
yeah, i use two of them and then i load the primary jack a little bit too. as long as nothing tips, i should be a-okay for weight. lol

Harbor Freight jack stand vs Amazon Jack stand
we don't have Harbor Freight in Europe
I wonder it how much it would cost for me to send you some from Texas
Both are from the same line.. Junk..
Brice Hysmith jacks are heavy so probably not cheap to send it
I dont know about the Jack stand but I have a harbor freight Jack that is 10 years old and I use daily on cars and suvs and it still doesn't drop or leak. For 75 bucks I'm impressed.
I'd like to see plastic car ramps vs metal car ramps
Yes
@@michaeldaigle7207 plastic ramps are actually very very strong. A lot of them are completely solid plastic inside. And are made of special compounds. The plastic ramps are like solid blocks.
I just made my own out of some 2x6s, 4x4s, and 2x4s
SPEED EZ man is injured by home made wooden ramps.😂if you trust it they must be good enough
@@tylermartin5560 my car weights less than 2500lbs
Imagine being this guy's neighbor. You see a hunk of a jack stand go hurling past your window and you're just like "Oh, is it 2pm already?"
😣 my aching guts I can’t stop laughing 😂
LOL 😂😂😂
hahahahaha
You can't just put a jack in a box, it's in its nature to jump out.
HAHAHAA THAT'S GOOD OMG
Nice
Hah thats clever
Underrated
Is this from something? My name is jack and this is my favorite thing I’ve seen on the internet sounds like a mad hatter quite or something lol
It's good to see the "Max Rated Capacity" is about 50% of the failure load. Nice margin of safety.
another thing is, most jackstand ratings are in pairs, so the margin of safety is even higher when testing only 1 stand.
it could also be trying to get you to buy the more expensive stand rated at higher load?
Yup these are covered under the ASME PACE standard, which specifies if memory serves a minimum proof load of 200%
@@randomchannel1167 No, its typical to try to design for about twice what the target is, for safety they don't want you putting close to the actual failure load. The higher rated one would have an even higher failure point.
7:22 "Crush everything and don't measure anything" My favorite line! :-D
I'm kinda partial to " Weeeeeee" when the window broke😆
I use a Nokia 3310 to hold my car up. It's overkill but I like to be safe.
Hahahahahah
We both have a black profile pic to
BRUH
😂🤣😂...🙌🙌🙌
I use mine on the side so I can still make calls. God knows the parts store always gives me the wrong parts.
From reading many of the comments this has probably been the most useful and informative video so far as well as being damn entertaining. Im sure many of your viewers like me are very greatful for a real destruction test. Really feel confident lying under a 2.5 tonne truck with 4 axle stands when in reality one will hold the weight. Great public service guys many thanks.
Imagine just walking down the sidewalk and seeing random chunks of twisted metal come flying through the window of some building. You look at the neighbor, who won't let their kids play in the side yard anymore, and he just shrugs like it's another weekday.
Ahh so glad I saw this video! Now I feel better about my four 6 ton jack stands to work under my 1967 VW bus and my wife’s car 😆
Remember this is not shear measurement. So if the car drops it is a different outcome.
@@TheKevo7777 if the car...... drops? I dunno how you usually use jackstands, but all my life with the way i've used em, its a constant load.. lol
That's serious overkill for the VW bus. You could've made do with milk crates (the steel kind that were in use back around 1970.)
(Yes, I am exaggerating slightly, but not nearly as much as the guy who's supporting a 2,700# vehicle with 48,000# of stands. And, yes, the prudent mechanic will prefer his exaggeration to mine. And, further yes, as this defensiveness is meant to advance-intercept UA-cam commenters who only get jokes when they have post-it notes on them)
@@TheKevo7777 I'm no mechanic (I don't even own a car and know basically nothing about car maintenance) but aren't you supposed to rest the car on the jack stands? Correct me if I'm wrong because like I said I know basically nothing about this but if I'm correct then why in the hell is your car falling onto the jack stands?
@@the_undead First you use some type jack to lift the vehicle and lift higher than you want it. Then you stick in a jack stand under the vehicle to support it. At this time, you lower the jack to allow for the vehicle to rest on the jack stand. Now, there are, manual jacks like the one that he tested last (the scissors jack. Note that, unlike the other ones, this is not a jack stand), pneumatic jacks (powered by pressurized air), and hydraulic jacks (powered by pressurized liquids). The last two require that you relieve the pressure by opening the relief valve. Most times is hard to control well how much relief to provide and the jack gets lower too fast, therefore, dropping the vehicle on the jack stands.
The "failure mode" of the jack stands is really important as well. They fail vertically without losing lateral stability, really important for safety.
Also they probably deliberately make it weaker in the vertical so that it's a controlled drop.
Wouldn't it be stronger in the vertical in order to drop slowly? If it was weaker it'd just crumple fast....
@@Jay-we2ek it's weaker vertically than laterally. That doesn't mean it's weak vertically. It just means it goes down when it breaks rather than to the side. The speed of the fall is significantly less important than if it sends shit to the sides uncontrolled
That's a pretty impressive safety margin. I have a set of really nice stands with redundant locks and I still feel nervous sliding under my 2200lbs vehicle. This video assured me that better stands are really goddamn strong compared to their rating. It's also impressive that the two proper stands failed gradually rather than snapping. Engineering has come a long way.
The fact that your wife is there guessing with you and entertained as well I think is awesome.
when she laughs it cracks me up!!
Uh-oh-uh-oh… not good at all. I want to have this as ringtone.
safetypin adds 3 ton, that is a mind blowing moment for me
Find a way to test just the safety pin.
@@sweettooth7124 he literally did in the video did you not watch it??? And it was with the safety pin they already damaged
@@thatguy1919 it appeared that the main catch was in place.
@@sweettooth7124 he cut it out
With the cast stand, yeah, that was encouraging.
The pin in the aluminum stand pushed down through the aluminum pipe like a warm knife in warm butter - the scenario I would be afeared of.
My inner engineer loves watching things go into their failure modes.
I was happily surprised to see the very gentle failure mode of the simple aluminium tube style jack stand.
It seems like the failure mode is at least as important as the failure load - you really want the stand to fail SLOWLY even at max pressure.
Good analysis!

"...but this time it was window next to the window we broke last year, that we haven't fixed..." really hit me in the feels lol
I can't imagine _not fixing_ a window in Finland, even in a shop, before wintertime sets in.
p.s. when I read the title, I thought it was talking about the plexiglass of the protective box on the press. I was surprised they broke a _real_ window!
Duct tape can't fix all problems
Great job! Keep up the good work!
I use jack stands but I have NEVER trusted them. I have always used tires under my car just in case. And Thank God I have always done that! Two years ago I accidentally bumped one of my jack stands and even though I had the safety pin in the jack fell immediately when bumped! If those tires were not under my car I would not be here to comment today!
Love to hear the laughter when you crush things. It makes me smile.
(Jagged metal shrapnel & shards fly out at high velocity, shattering windows, potentially causing serious injuries.)
Lauri: "Wheeeeee!!!!!"
“ you couldn’t see shit from that!” Haha instant sub 🤘🏼
I wonder how the jack stands would stand up against the smashinator? Sounds really dangerous ^_^
OMG the extra content. I love you guys.
The scissor jack really impressed me! 3000lbs rated, held 9000lbs 💪
"...crush everything and measure nothing." I really love the relaxation this channel provides. Thank you!!
That aluminum cylindrical design was surprisingly strong. I'm quite impressed with that thing. The base is a bit small though. Like it might fall over easier.
Timo is going to revoke your Hydraulic Press privileges if you keep breaking his windows.

BTW, thanks for doing this test! I've got a set of the safety-pin jack stands, and it's great to see just how strong they are.
Awesome stuff. I'm glad no one was hurt. It shows how dangerous a press can be even when using shields. But they are still an essential piece equipment and you make great videos
I love that you actually speak during your videos and explain what you are doing. Also you don't have awful music. Great videos! 👍
It’s in the safety box - aaand now it’s out of the safety box.
Thank you uncle dracula, great video! I'm glad I purchased the round pin style stands!!
Just found your channel this morning. Most excellent!
Thank you very much for this video, been waiting for it since last test you made

Thank you for doing this. I was actually wondering about this, while laying under my truck 😳
I love this interesting channel! Thumbs up and subscribed!
I just bought that "2 tons jack stand" yesterday from _Biltema_ here in Sweden. This test makes me feel quite safe it is enough for my Volvo XC40... Great video!
When your harbor freight jack starts making weird noises
Impressive! So each one of those are almost 4 times stronger than what they are rated for, which is great!
It's so awesome that their is a channel dedicated to Hydraulic pressing stuff. Thank you.
Makes me feel more confident about using my jack stand pair, thank you.
Makes me feel a little safer
No joke, good to know if you use 2T jac stands for a car you can throw them under a big truck and still not have to worry about any snapping or crushing you
The main thing with these was that they all withstood at least 2.5x the force before breaking. Not really sure but i'm sensing a trend here, perhaps a government mandated safety margin they can be rated? Also we have to remember that the force rating is for repeated use. Going near the limit once will deform it and shorten it's lifespan. So 2 tons for a 2 ton jack stand. But in a tough spot and no persons under the load........
Side note: this of course only applies if the country has a *functioning* safety standards office that regulates and bans low quality items that do not meet the standards or are outright dangerous.
@@alaric_ No country has a functioning government like that. You really think an army of Gov. boffins in white coats are testing all the products out there? On a side note, I use these types of jack stands to prop my boat trailer up, and they're remarkably easy to activate the unlock thing and have them collapse. The ones locally here don't have that safety pin and I wish they did, to the point I'll now look around and see if I can find some that do.
@@alaric_ yes, it's called a safety factor. and most... well, things produced have such a thing, chain, slings, etc. and to be frank, it's easier for the manufacturer, if they make a jack stand that actually can support 4k-5k, but safely (hence, safety factor) rate it for 2k, they aren't going to be responsible if you load it up with 5k.
6:43 Crazy how you can see the paint flex on the scissor jack almost instantly.
That was just the metal distorting slightly as it got loaded which changed the direction of the light being reflected.
One of your best most relevant (to me) videos.
Thanks for this one.
Excellent video, love to see these test. Allows me to feel comfortable when using a 3/4 ton jack stand knowing that it could stand more than what it is recommended not that I'm going to go over that but is good to know. Liking you channel 😁

You understand the gravity of this situation very well.
Wingnut Stickman do I need to see you out or can you see yourself out...
“It was pretty god damn good”. 🤣 Love it.
Thanks. I was always worried about the first axle stands you tested. The look flimsy, but now I know they will support my truck, I'll get some. Cheers....
Very informative. Again, thank you!
Yeah I wasn’t expecting that much safety margin that’s pretty good
"you couldn't see sheeeeit fdddum dat"
LMAO 😂😂😂🤣😂 I WAS DEAD I DIDNT EVEN FINISH THE VIDEO
Another fantastic video. Thanks for sharing!
Great video! I've never seen your channel before.
I have four of the aluminum stands for my BMWs...gives me confidence.
Your wife's reactions are awesome!
Ciao!
And for todays bonus content, we have 'Ayleyen frohm vehnus' LOVE THE ACCENT XD
The scissor Jack surprised me. They come in a wide range of quality.
The aluminum stand would take more if it had a fatter pin.
Have you seen the half scissor that Volkswagen uses. Those fuckers are terrifying to use just to change a tyre.
What a simple yet awesome channel topic. Genius
You guys have WAAAAY too much fun on this channel! ;-)
For how often I trust my life to these things, this video gives me the warm fuzzies.
Surprising! The press shows how brittle aluminum really is compared to steal. 7:26
steelshade you have “steel” in your name and yet you misspelled it in your comment. ????
@@Wild_Bill57
I'm kinda dumb sometimes. In a hurry, mind wanders, don't double-check, never perfect, on and on, just like everybody else. I typically don't double-check short, quick, comments, opportunity cost, you know? And here I am contradicting what I have just stated. Life's strange that way. Guess I'm only an imperfect human after all. Who would have guessed?
The brittleness was because the aluminum was cast.
steelshade you know that you can fix it, if you want? I usually proofread mine after posting, then just edit them. Just sayin’.
@@Kahsyrbag i think it work hardens too right?
Superb! Thank you for showing the failure points of these jacks. This provides confidence for DIY'ers who rely on these. Just like car crash report, each jack stand should be required to have test report like what you have done.
Thank you! Amazing how strong they are
Thank you for converting the numbers for us non-metric Americans.
1 kilo is 2.2 pounds bro, literally the easiest conversion ever
7:50 Lol,broke window..now use safety shield:):)
Then they added the shield and didn't even bolt it closed.
wow! so good to know that they can actually handle way more than what they are rated for. I often work on my own car and use the ones with the cast iron rod, mine doesn't have the safety pin though.
You guys are fun to watch. Thanks for the laughs from 🇨🇦
Why did this pop up on my recommendations... I'm glad.
very good. love Anni 's laugh
The only thing why i watch these videos...

Very informative and Entertaining!!!

I have owned alot of that first stand. Nice to see that if set properly it will hold at least twice as much 👍thanks for the video my friends !
Very entertaining !!! The hydraulic press is my most favourite workshop tool !
Whenever I jack my car up I put the jack stand underneath it and leave the Jack underneath it for just in case
Same.
I also add some scrap blocks of Parallam engineered wood beams also.
Jack stands always struck me as unstable one trick ponies - buy them, store them, use them once in a blue moon. Bricks and blocks of wood have served me well so far.
@@teaCupkk Jack stands are plenty stable if you position them correctly. It's good practice to shake a car that's on them before getting underneath anyhow
Yep, I use jack stands, then also put my winter wheels underneath the car for added safety. According to this video might not be necessary, but i'd rather have the redundancy and stay alive than trust only one method and have an accident.
@@kw9849 Jack stands assume your car is on level ground, where I live it's not the case. They would also just add to the ever growing inventory of not that useful stuff I have to manage. For the sake of simplicity and stability, I just keep a stack of bricks handy, they cost nothing.
first just want to say it's an interesting video, thank you for sharing. Now, I don't think you are actually measuring the point of failure, even if it's showing 12 tons if you load it with say 5, 6, 7 ... 10 tons and keep it there for 1 minute for each, it might fail sooner than the max you see, going as fast as you do doesn't allow for the metal to deform and fail in time (which is the scenario you have when placing a constant load on it when jacking up the vehicle).
The heaviest vehicle I have is just over two tons, and the vast majority of people will be in that ball park, so a stand failing at five tons could have two and a half vehicles on it, as the sole support, its good to know that even the cheaper ones are more than man enough for the job.
Love this. Thank you for sharing.
Glad everyone was ok, awesome video
I didn't hear you say how much the first jack stand at 1:00 was rated for, unless I missed it.
2000kg
@@oisin3495 Thank you!
BIG Yellow sticker on the jack where it says - MAX 2000-KG... :)
Lol i am subbed to you i think. Its strange i keep seeing comments from folks im subbed to on good channels.
@@bentboybbz as opposed to seeing them on bad channels? 😝😂
"Bump it slightly and it goes down" Sure if by "slightly" you mean 0.5-1.5 tons. It takes about as much force as it is holding up to lift the release lever
Extremely informative.
Good stuff, fun to watch.
So I've grown more respect for Jack Stands after watching this.
6:55 The "widow maker" on full display.
It held almost 10 thousand pounds. Like what are you trying to say
@@YungEagle3k I'm trying to say those jacks are commonly called "widow makers" because they have a bad habit of slipping sideways.
Put one under a sill, jack the car up 6 or 8 inches so the thrust angle changes and you'll probably see for yourself.
Surprising numbers! I figured they would take a bit more but not that much of a difference. Great video.
Great stuff. Thanks!
i am surprise that scissor jack hold that much weight
Harbor freight jack stand gets 40lbs on it: 💥
I wanted to see them use a HF stand and just watch the welds just split.
MAX 2 tonne sur l’étiquette c'est n’importe quoi il va jusque 5,5 tonne max.
I still squint my eyes and flinch on these videos, yet, I'm full well aware these are never going to hit me lmao.
Really impressed to see the aluminium jack stands withstand so much pressure. I’ve the same jack stands and never used them as I thought they’d not be able to hold my Range Rover up.
Never liked them because of their short base
Do a safe box & combination locks 🔒!
Need to know what brand/model these are, with all the recently recalled jack stands, people need to know which ones work.
They are most likely the ones sold by the nordic hardware store called Biltema.
Watching this channel so so cathartic.
I`m happy that you guys tested the 2T axle stand. I feel much safer now under my car, thx guys :)
Make set up like 5:30 try shearing pins made of various materials.
I think the pin just cut through the aluminum
Oh snap!
Epic as always!
Love this channel!
