I have something for you...PARACORD. This is not a main cord in rock climbing, but it's certainly one of the most versatile and useful cordages ever! The problem is that there is no strict regulation so the quality goes from one extreme to another. It would be awesome if you could do tests and explain the differences between military, commercial, and ultra-cheap ones.
As an arborist, I want to see a video testing when various friction hitches start to slip. Also would love to see a thermal image of the rope during testing
Likewise. Hopefully he'll continue to upload more of these videos with arborist equipment. That's a common harness we all know good to see it lives to upto rating.
Hi Ryan. Big wall climber and professional Arborist here. I'd love to see you test more tree gear. There are so many nuances within both disciplines (rock & tree). With your set up and production style you could make a huge impact within the professional & recreational tree climbing communities. I recommend reaching out to some skilled / knowledgeable Arborist's for idea's on specific gear / situations they'd like to see tested. Keep up the great work! Cheers.
I agree. Phillip (Phil) Kelley would be a great name to reach out to here in the states. Used to be a huge production climber, prior North American Training Solutions instructor, current lead safety at Wright tree service who is huge in the states for line clearance, also doing wonders in teaching aerial rescue across the United States to arborists & helping assist fire departments become more familiar with arborist hardware to help assist them with aerial rescue.
What did you do to become an arborist? I'm looking for a career change at 30. I love climbing and I'd love to hear what it takes to become an arborist.
@@jeffreysandone Reach out to local companies around you. You will likely start off as a groundsman. You'll learn the workflow and eventually be able to shadow a climber.... In some area's there are recreational tree climbing meet ups. That is also a great way to meeting people in the scene.
Yes test more arborist gear. As an arborist it’s all super informative. One big thing I’m interested in is side loading a carabiner around a branch or log
To be sure I use a Notch quickie shackle for choking anchors in trees, but there are times when a carabiner could be convenient. I am very curious to know if a carabiner which has an ANSI rated gate is super good enough when used as a choking anchor around a tree/bollard. If aluminum is a no, perhaps a steel ansi biner?
@@asontehunsthanshhl So, I guess a thermal camera would get mostly a post mortem look after a pull...might get a few lucky frames during the pull as well.
Only American is limited. Buy chinese for the same price and get almost double pixels and 3x the framerate. Reccomend infiniRay pro. I have a flir one pro and it is garbage and app totally suck, can't use one phone older than 2 or 3 years old as they remove the compatibility from the app..... And support ain't willing to help at all..
Same! the ratings say one thing, but there's so much dirt and gunk that gets in them, and prolly wears them, I'm super interested to see a very worn, slightly worn, and new swivel break test.
I don't trust swivels and don't use them for life support. Those interested in actual break test info...I wonder how much it would take to request a "pay to test" situation? Then invite climbers to chip in on test cost. X cost divided by 10 or 20 very interested people could make it doable in short order.
Love that you are covering other disciplines. Maybe doing a gofundme to see if a bunch of first responders or other professionals want some specific tests.
Thank you so much for taking the time to test arborist gear! Im a long time fan of you channel, and an Arborist! This is potentially life saving gold for me, and the industry as a whole!
Hell yeah. This was very helpful in showing how used gear breaks down over time & use. As an entertainment climber I would like to see testing on the lifelines & how the 'soft stop' attachments perform.
Arborist here! Love it! break more stuff! try and get hold of a zigzag and. any of the other mechanical climbing devices that are getting more popular in the industry. Also at what point does a toothed ascender e.g pantin of jummar strip a rope !
That ascender one is great. Nugreen store used to have a video up of the second gen zigzag getting pulled against a rock and the swivel yanked out at 9k pounds.
Always wanted to see you test some arborist stuff.. good on you for "branching out" lol looking forward to more in the future. Thanks for all your work testing gear and making videos I know we all appreciate it.
As a former climbing arborist that only climbes every once in a while. It's good to know that the gear does not degrade that hard if you keep it well maintained... Thanks you guys!!
Ryan and extreme gear dude, thanks for including us, super appreciate all your work, as an arborist for 15yrs and a rock climber for 26 yrs, I've found your tests really fun, informative, and cool.... and def gonna shop your site... I've been trying to find those soft shackles on there but no luck, any help?? (i know that stuff is easy to splice, but i barely have time to sharpen my saws... Would much rather buy from you) Also, i could send in an older swivel i use on my bridge, and donate the same one new if you want to do another Arb specific vid
Keep testing arborist gear, it might encourage more regular inspection/replacement of gear. Also it would be interesting to see tower load testing of dropping a 6 foot section of decent diameter trunk to test some of the rigging that is designed to catch it before it hits the ground. Arborists generally do this with bigger than 1/2 inch rope but would 1/2 work and how many times? Is static line better than dynamic for this?
1/2” rope definitely works! We use that diameter most of the time for lowering all but the biggest wood. It’s a lot nicer (easier) to handle than the bigger ropes, (especially for the climber) but it does have its limitations.
I always say keep the to 500 lbs. Yeah I've roped bigger. But it's a rule of thumb. The big factor is letting it run and slowing it down, not slamming it to a stop. It pays to have a guy on the rope that is good. Physics says that the force required to stop an accelerating mass approaches infinite. That is why locking off a large piece or a hard stop breaks things and can get someone hurt or killed.
The sideways bridge plate test was pretty cool, especially considering how it flipped itself around after breaking. The confusion in your voice followed by relief when you figured it out was hilarious!
Nice video. Glad to see some arborist gear tested. Unfortunately some of the arborist and cell tower climbers have worked with sketchy companies where the training on their gear is less than good enough.
Don’t know about tower climbers, but my personal experience as an arborist (and talking to other guys) would lead me to believe that a BIG percentage of arborists receive little to no training before being told to “get up there and get the job done!”
I'm an arborist and I enjoy this channel because it helps me figure out new ways to connect ropes when rigging or tying and more... plus who doesn't like seeing gear destroyed. As for the rope bridges, I believe your results would be higher than real world since the attachment points on a saddle are 2ish feet apart rather than side by side like your quick links. That being said, in my experience most bridges end up retired from abrasion or saw nicks and probably never see much more than 2kn. I can definitely dig up some old gear to send it to see how the years of abuse have affected it.
Wow! you broke my heart breaking a great harness that I will never be able to afford. I am a volunteer as a tree climber with a disaster relief chainsaw team. I buy (or make) all my own gear. I enjoy seeing how well things hold up, it gives me a lot more confidence in the gear.
I'm excited to see this, because I recently bought ultra-sling made from the exact TenexTec rope you shown. My is rated for 69 kN, so glad to see 77 kN in your test.
Yes, more arborist style testing please! I’m hunt from a saddle and there is tons of gear that is sold to hang from a tree but isn’t tested and has no standards! We’d love your help learning what is “super good enough” and what isn’t.
Love the arborist material. That’s my focus, but I’m always looking for other fields to see what can cross over to tree climbing, and that’s how i came across your material. I’d like to see cross loading of snaps. They get used all the time instead of knots during rigging. That’s where the big loads are in tree work, so when I hear you say 4kn is good enough, I have to always come back to just the climber is good. It would also be interesting if you could work with TCIA or another group to gather used tree ropes from rigging and climbing. I’ve seen ropes break that look almost new and it would be interesting to see how much is on the failure side of the curve because of repetitive shock loading. You generally test max strength, but the manufacturers also have failure plots that I’ve wondered about. For example, would a rope really break at 50% load after 20 pulls?
Love the tree motion harness break test! I’ve seen more tie in / rigging points on trees fail rather than the gear itself. Would be interesting to break test branches / crotches of trees since they seem to be the weakest link in many scenarios.
Love it, thanks for getting some arborist gear it there. I use everything you broke on a daily basis. Also thanks for adding arborist gear to the store.
This is great! I just spliced myself a rigging sling with 5/8 tenex last week. Thanks for showing me that my gear is super good in a direct pull. But I'd love some tests with rigging on the drop tower.
I love that you branched out. I would totally buy three of the top selling arborist mechanical devices from your dude so he can send them to you unscathed to break. Mainly because a lot of them are not mbs rated. And if he doesn’t stock them I can have them mailed wherever you like. Climbing minds want to know 🧐
Thanks for doing this. I have a Petal swivel on the bridge of my harness... I'd be curious to see how hardware like that and that Notch rook pulley/ rigging plate hold up. I know these are all expensive pieces of gear so, again, I really appreciate you taking the time and spending the money to do this. I've used bee-line eye and eye cords in the past (currently using HRC by Teufelberger) and always wondered if they're super good enough... this is really helpful and gives some good peace of mind!
BeeLine is awesome stuff. The vectran core is self-abrading tough so it is wise to replace it at regular intervals, not just when the protective jacket starts to signs of wear. Obviously even used it is super good enough, but for $20 a hitch cord it really is easy to just chuck the old one and use a new one. Besides, there's nothing really as nice as a new fiction cord.
Definitely like the idea I read a few times of setting up a go fund me to get some popular arborist gear tests done. I know A TON of the community will throw in what they can for it. I also know manufacturers have in the past been more than happy to throw in donation gear to informational things like this. I’d definitely reach out (if your already a supplier then you’ve already got a contact). If a go fund me is set up then start up a pull to find what the arborists out there would like to see tested with the funds we have donated. I know a HUGE cation right now is swivels with the DMM recall recently. My favorite thing to see in this video specifically is used gear. I don’t think people get the importance of replacing gear in a timely manner till they see the difference between a new piece of gear & a well used/moderately used piece of gear.
I also liked that the used gear was still breaking at pretty high kN, i prob replace my gear TOO often considering how bad some of that looked but was still pretty strong... Rigging gear that's worked and worn on the other hand, or ppe that's been subjected to shock loads, YES even if it doesn't look bad... Destroy and replace.
2:09 I didn’t know they made rope out of dynema. I just kind of learned about the stuff a couple months ago because of a company using it for ballistic armor. It seems like some cool stuff. I’ve recently become interested in learning more about some of the products and chemicals that get used to make stuff that we use (ex: rope)
I gave up arborist work many years ago here in the UK. we used Prusik loops tied with a double fishamans knot. we tested these at 20KN and had no slippage. we found that rock climbing techniques didn't relay work for tree climbing and work positioning. We found the Prusik not you used could become loose and the climber fall from the tree. Our safety margin on ropes was 5x stated for climbing ( 1 tone stated would fail at or above 5 tone) and 10 times stated for lowing roped ( 5 tone would fail 50 tone or above)
such a cool video! just today i spliced that same tenex material into a rigging sling. seeing what it actually takes to break it fills me with confidence! have an upcoming Fir removal and will be negative rigging out chunks that will weigh up to 1500 ish pounds
This is great. Thanks! I'd love to see some videos of ropes and/or other soft stuff being strained multiple times and then tested. One of the things they teach in certification classes is "cycles to failure". i.e. if you load a line past its WLL multiple times it will weaken significantly. I've seen rigging ropes put under a *lot* of force...as in crunching through the bark of a tree the rope was wrapped around and denting the wood underneath. Or hooking up a bobcat to a 3:1 advantage to barely pull over a very large tree. What is the breaking strength after a 46kN rope is loaded to 35kN 10 times or 20 times? Those ropes continued to be used heavily. I don't work there anymore. Many tree companies abuse the crap out of their rigging equipment and this would be useful information.
The rings are meant to used 2 per attachment for life support, hence why the bridge goes through two lower d rings. The rings you broke individually are meant to be used together.
Please do more prusik eye to eye, but please double it over. As an Arborist, we never use an eye to eye without a bend. Also, to test the friction pull, use a heavy 5/8 static rope, and spiral the prusik 4+ times at the top. More coil=more friction.
That break when settling reminds me of a time I was pulling a dock out on a braided rope. It was pulled out and when the truck went into park and rolled back a few inches the rope disintegrated. Three feet of rope that had pulled the dock out turned to dust.
You guys should go back and do some more tests with those GM Climbing rappel rings. There actually to setup a rope retrieval cambium saver/friction saver and id love to know what they and other friction savers and flip lines break at.
You guys should get a lazer thermometer and then you could record how hot the ropes and prusiks get, as they are slipping and after they break. Great content, thanks friends!
Biggest thing I see most pros ignore is the log weight chart. Every crew must have one on the truck by law. Every log you estimate the weight based on species length and diameter. After a while you get a feeling for it and you can stop checking the chart for common tree types. This simple knowledge can prevent so many stupid accidents you will never see coming otherwise
It's kind of crazy, a 5/8" sling isn't really considered big gear for tree work. 3/4" rope is normally the big stuff for rigging, and your sling needs to be a lot stronger, unless you're using a double whip configuration or something like that. I would love to see some testing of arborist rigging configurations under dynamic loads. It's amazing how scarce hard data is for this sort of thing.
I appreciate this content. I just spliced my own pocket rigging sling from this same rope. My sling relies on triple? Locking Brummel splicing and chokes through itself.
I couldn't tell for sure, because it went by quick in the video, but the Brummel Splice looked odd to me. A mobius brummel should lay out smoothly instead of having that lump on the start of the bury. Break out your copy of Brion Toss's book and double check that the locking brummels were on the correct part. Also, I'm told that the MBS on rope is actually measured/tested with an eye splice on both ends, so if you're seeing less than the rope rated strength, your splices are bad. You should not be losing 10% due to a splice. Keep up the testing it's always interesting to watch!
The way that the bridge plate breaks at 13:50 is super cool! Pretty unique compared to most other stuff breaking on this channel?! Like usually steel deforms a lot before it eventually tears and aluminum usually seems to break different from what we see in this first bridge plate test as well, right? IIRC aluminum also usually breaks in two spots... In this breaking test here it looks like the ring splits open in only one spot and then bends just enough for the carabiner to come out... I'm wondering if that's what happened or if the narrow gap is actually a piece of the metal that went flying somewhere? Since normally aluminum almost doesn't deform at all before it breaks. On the 2nd bridge plate test the way in which it broke was much more reminiscent of the usual breaking of aluminum gear I've seen from all your other tests.
I'll be honest.. I started going down the climbing gear knowkedge rabbit hole maybe a year ago. While I've been on some indoor walls I'm NOT a rock climber (maybe low grade stuff in the future, just not my bag) But I DO intend on "sport" homeowner side tree climbing (and tree work) a. because of the fun/exercise factor and because I have a decent size property with some farm stuff on it. While I have some rocks and outcrops none are over 25 feet tall. Thank you for talking arborist gear. When stuff gets bought, some WILL be coming from your vector. Thanks. Did I also mention thanks?
So, I know this is costly, and probably has already been suggested a few times, but having a thermal camera recording the gear stretch and heat up would be really cool. Not sure what data it could bring, maybe parts heating that do not break but would be next in line?
Man, your work makes my work less stressful. Thankyou. I have enough to think about in front of me, I don't need to worry about my kilonewtons exceeding my kilo threads.
Hi, it would be great to see how ropes & notes perform when wet. I appreciate the kN (& lbf) values, but may not make the kN to kg link (10kN = 1019kg). It may be helpful to also include the kg value. I'm neither a climber or arborist, but use ropes for truck & trailer load tie-down, so I'm finding these videos facinating. Keep up the good work.

Love the arborist work gear! The other gear tests are great but work is work and playing is playing
As someone who has snapped tenex. That stuff sound like a shotgun when it lets loose. Interesting to see how it broke after you stopped pulling.

Obviously even used it is super good enough, but for $20 a hitch cord it really is easy to just chuck the old one and use a new one. Besides, there's nothing really as nice as a new fiction cord.
The arborist gear is much more informative for me but I’ll watch you break anything and hit the like.
Awesome seeing all the different tests being done, keep it up Ryan!!
Awesome...! I use all that stuff every day, I've an arborist for 40 years. I definitely will be purchasing gear
Curious to see how meny views you get on this compared to regular break tests... I have a feeling you will gain a whole new sub set of subscribers 😉
Definitely like the idea I read a few times of setting up a go fund me to get some popular arborist gear tests done. I know A TON of the community will throw in what they can for it. I also know manufacturers have in the past been more than happy to throw in donation gear to informational things like this. I’d definitely reach out (if your already a supplier then you’ve already got a contact). If a go fund me is set up then start up a pull to find what the arborists out there would like to see tested with the funds we have donated. I know a HUGE cation right now is swivels with the DMM recall recently.
My favorite thing to see in this video specifically is used gear. I don’t think people get the importance of replacing gear in a timely manner till they see the difference between a new piece of gear & a well used/moderately used piece of gear.
I also liked that the used gear was still breaking at pretty high kN, i prob replace my gear TOO often considering how bad some of that looked but was still pretty strong... Rigging gear that's worked and worn on the other hand, or ppe that's been subjected to shock loads, YES even if it doesn't look bad... Destroy and replace.
The video where you tested those rings was one of the first ever videos I watched of yours. Now I'm hooked and want to climb one day.
Yesssss! More arborist gear testing, please!
So Dope! Thank you for this one! Wanted to see those Cobra buckles get tested for a while.STOKED!
quickdraws! the differnt types and alll that good stuff, was surprised i could not find anything about them
Wooohoooo! Arborist gear!!!!! Love it. Love the arborist vids
2:09 I didn’t know they made rope out of dynema. I just kind of learned about the stuff a couple months ago because of a company using it for ballistic armor. It seems like some cool stuff. I’ve recently become interested in learning more about some of the products and chemicals that get used to make stuff that we use (ex: rope)
Really glad you broke the buckle. I have them on my hunting saddle. Never trusted them until now.
I gave up arborist work many years ago here in the UK. we used Prusik loops tied with a double fishamans knot. we tested these at 20KN and had no slippage. we found that rock climbing techniques didn't relay work for tree climbing and work positioning. We found the Prusik not you used could become loose and the climber fall from the tree.
Our safety margin on ropes was 5x stated for climbing ( 1 tone stated would fail at or above 5 tone) and 10 times stated for lowing roped ( 5 tone would fail 50 tone or above)
such a cool video! just today i spliced that same tenex material into a rigging sling. seeing what it actually takes to break it fills me with confidence! have an upcoming Fir removal and will be negative rigging out chunks that will weigh up to 1500 ish pounds
Props to Arbsession for the stitching on the hitchcord!
Really like the Arb tests 👍 Thanks from UK
As rec tree guy because I have more access to that than rock - I love the idea that you’ve crossed over here.
"it's hot" "feel the tip" I feel like I heard that somewhere else :P
This is great. Thanks! I'd love to see some videos of ropes and/or other soft stuff being strained multiple times and then tested. One of the things they teach in certification classes is "cycles to failure". i.e. if you load a line past its WLL multiple times it will weaken significantly. I've seen rigging ropes put under a *lot* of force...as in crunching through the bark of a tree the rope was wrapped around and denting the wood underneath. Or hooking up a bobcat to a 3:1 advantage to barely pull over a very large tree. What is the breaking strength after a 46kN rope is loaded to 35kN 10 times or 20 times? Those ropes continued to be used heavily. I don't work there anymore. Many tree companies abuse the crap out of their rigging equipment and this would be useful information.
Love knowing the stuff I have used would have held if I had taken an air step. Love watching yall break gear in the name of science!
The rings are meant to used 2 per attachment for life support, hence why the bridge goes through two lower d rings. The rings you broke individually are meant to be used together.
You should try to film this stuff with a thermal imaging camera to see the heat from start to finish! That would be super interesting
Like the arborist gear. Eagerly awaiting rescue gear.
As part of your branching out in the arborist gear you should really try some of these hunting saddles
Please do more prusik eye to eye, but please double it over. As an Arborist, we never use an eye to eye without a bend. Also, to test the friction pull, use a heavy 5/8 static rope, and spiral the prusik 4+ times at the top. More coil=more friction.
That break when settling reminds me of a time I was pulling a dock out on a braided rope. It was pulled out and when the truck went into park and rolled back a few inches the rope disintegrated. Three feet of rope that had pulled the dock out turned to dust.
You guys should go back and do some more tests with those GM Climbing rappel rings. There actually to setup a rope retrieval cambium saver/friction saver and id love to know what they and other friction savers and flip lines break at.
You guys should get a lazer thermometer and then you could record how hot the ropes and prusiks get, as they are slipping and after they break. Great content, thanks friends!
Biggest thing I see most pros ignore is the log weight chart. Every crew must have one on the truck by law. Every log you estimate the weight based on species length and diameter. After a while you get a feeling for it and you can stop checking the chart for common tree types. This simple knowledge can prevent so many stupid accidents you will never see coming otherwise
This was sick. I use that same harness for work. Solid work
It's kind of crazy, a 5/8" sling isn't really considered big gear for tree work. 3/4" rope is normally the big stuff for rigging, and your sling needs to be a lot stronger, unless you're using a double whip configuration or something like that.
I would love to see some testing of arborist rigging configurations under dynamic loads. It's amazing how scarce hard data is for this sort of thing.
I appreciate this content. I just spliced my own pocket rigging sling from this same rope. My sling relies on triple? Locking Brummel splicing and chokes through itself.
I couldn't tell for sure, because it went by quick in the video, but the Brummel Splice looked odd to me. A mobius brummel should lay out smoothly instead of having that lump on the start of the bury. Break out your copy of Brion Toss's book and double check that the locking brummels were on the correct part.
Also, I'm told that the MBS on rope is actually measured/tested with an eye splice on both ends, so if you're seeing less than the rope rated strength, your splices are bad. You should not be losing 10% due to a splice. Keep up the testing it's always interesting to watch!
The way that the bridge plate breaks at 13:50 is super cool! Pretty unique compared to most other stuff breaking on this channel?!
Like usually steel deforms a lot before it eventually tears and aluminum usually seems to break different from what we see in this first bridge plate test as well, right? IIRC aluminum also usually breaks in two spots... In this breaking test here it looks like the ring splits open in only one spot and then bends just enough for the carabiner to come out...
I'm wondering if that's what happened or if the narrow gap is actually a piece of the metal that went flying somewhere? Since normally aluminum almost doesn't deform at all before it breaks.
On the 2nd bridge plate test the way in which it broke was much more reminiscent of the usual breaking of aluminum gear I've seen from all your other tests.
Love it! Thanks guys, I'll check out the arborist gear you've added ✌️
The French VT had me cringing!! I’m a climbing arborist and appreciate this. Give me a peace of mind knowing my prusik is safe with my weight.
I'll be honest.. I started going down the climbing gear knowkedge rabbit hole maybe a year ago. While I've been on some indoor walls I'm NOT a rock climber (maybe low grade stuff in the future, just not my bag)
But I DO intend on "sport" homeowner side tree climbing (and tree work) a. because of the fun/exercise factor and because I have a decent size property with some farm stuff on it. While I have some rocks and outcrops none are over 25 feet tall.
Thank you for talking arborist gear. When stuff gets bought, some WILL be coming from your vector.
Thanks.
Did I also mention thanks?
I am not an arborist, but I do use some spliced tenex for other things, so this was very interesting.
So, I know this is costly, and probably has already been suggested a few times, but having a thermal camera recording the gear stretch and heat up would be really cool. Not sure what data it could bring, maybe parts heating that do not break but would be next in line?
Feeling pretty confident about Teufelburger rope bridges after seeing that old ass one breaking at 22kn. 🙌
Man, your work makes my work less stressful. Thankyou. I have enough to think about in front of me, I don't need to worry about my kilonewtons exceeding my kilo threads.
I climb with the same treemotion saddle. Love seeing this.
Hi, it would be great to see how ropes & notes perform when wet. I appreciate the kN (& lbf) values, but may not make the kN to kg link (10kN = 1019kg). It may be helpful to also include the kg value. I'm neither a climber or arborist, but use ropes for truck & trailer load tie-down, so I'm finding these videos facinating. Keep up the good work.
