@@MadMatt4WD Hey Matt, I saw a video of someone using a length of reasonably heavy chain, around 1.5m long, as a damper. It was clipped to the winch rope with carabiners. Are you willing to test this method of damping? For my mind it seems like a good idea, they had it at the mid-point, I'd like to see it at the heaviest point ie. At hook or shackle/failure point like a snatch fuse

[@MadMatt4WD]

@@Duke-le6vy I’ve heard of that idea but never tested it. I could look into it. The drawback is the chains weight.

[@motorvatorv888]

Me too. I still think MattUSA should be using dampers, especially when recovering cross overs and rental vehicles. I have a suspicion that a few of them have gone back with slightly bent suspension. That said, many of his recoveries would not approach a wood filled big hole for anchor effect.

[@jimclark6978]

Matt, real interesting concept, if you look at the free fall on a safety lanyard for working at heights this is folded and stitched in a concertina this allows for a longer length of safety strap and more likely control of the recoil

[@johnlatsch9720]

Exactly what I was thinking

[@RaggedsEdge]

The stitching isn’t just to shorten the tether, the stitches act as energy sinks as they blow apart when it’s stretched.

[@darrenbradbury8667]

Hi, great video. I love watching other people break stuff. I thought that tether looked a little short. I’m wondering if you or the manufacturers have discussed using a suppressor similar to that used in a lanyard for fall suppression when working at height. Picture this, the tether is 3m long, 1.5m of the tether is folded upon its self until the length is only 1.5m. The bundled tether is then stitched together in a fashion that is weaker than that of the anchor stitching and placed in a protective cover. The idea being that the tether is long enough that the snatch strap has returned to its static length before the tether loads up. Then if there is still enough energy, it will be dissipated when the suppressor stitching fails, leaving the tether intact. Keep up the good work!

[@MadMatt4WD]

I’ve discussed that concept with manufacturers and they couldn’t care less. Very disappointing.

I Had never heard of the tether, however i love the idea, as an Engineer, its totally the better approach, im pleased to see you guys working with who ever produced it to refine same, its far better than any ballast hung over the snatch strap, which could easily be misused, the tether just needs to ba a bit longer and slightly elastic, the idea being when the snatch fails, its long enough that no serious pulling load transfers to the tether only the load of the failed snatch strap, great work guys, John Gurney

[@budget4wheeling641]

Hi Matt, good to see someone doing shock load test instead of bench test. How come you used soft shackle instead of bow shackle ? 4wd "SAFETY" is a large can of worms. Doesn't matter how safe the equipment is there will be those that don't use it correctly. There's a video of people snatch/towing a newish Prado out of water with hooked on the bull bar not tow/recovery point. If tow balls are so prone to breaking when used in recoveries, why did Ronny Dahl have to cut them and still took several attempts to break them off ? Also what's the point of "RATED" recovery points when what they bolt to isn't that strong ?

[@MadMatt4WD]

No real reason to use soft over bow. Both are good and safe. Yes it is a can of worms and yes I saw the prado vid and just shook my head. Towballs are a single shear item rather than double shear this is the reason they're dangerous. Just because it took a few goes to get one to fail doesn't meant they don't fail. There are numerous vids of towballs failing. Totally agree with you. This whole rated recovery thing is not that helpful and provides a false sense of safety IMO. Unless the complete recovery solution is tested it's just one item thats rated. IMO to call it a rated recovery point it needs to be tested as fitted to a chassis. I'm sure some are but not all. I prefer to use the term suitable which is more vague but removes the false safety element.

[@budget4wheeling641]

As for improving these tethered straps, first should the tether be of the same rating as the strap and maybe a Joey pouch to hold a few metres of the tether so the driver has time to react.

[@budget4wheeling641]

@Low Range 4wd WA I have my moments. The problem is the end user, will they use it correctly ?

[@budget4wheeling641]

@Low Range 4wd WA IMO there is to much focus on numbers IE how many KG's something can hold pull extra. What's the point of a 5000kg "recovery point" when what it's bolted to isn't rated. How many 4wd have a tow rating of 5000kg on the front ? How people actually know what swl or wll means or what the percentage factor means or what the difference is between them and breaking point. When I learnt, I don't remember hearing about people being hurt, but back then we also learnt from doing it with our elders and it was a privilege to do it due to the cost. Unlike today, most items are a lot cheaper and people just do it without any form of training or knowledge.

[@JohnSluderPhoto]

Suggestion, have the tethers sewn up with a "zipper" style the treads are designed to "peel" apart in layers to absorb the energy

[@MadMatt4WD]

yes

[@rusty78yak]

Agree, same concept as a shock absorber in fall arrest systems.

[@dachet10]

Or do it like fall arresters so they break in stages, each absorbing part of the force.

[@davidnorthrup3674]

Hello, I found your channel through a link in Matt's Off Road Recovery which I watch a lot. Thank you for the video, I did learn a bit from it which is why I watch these videos of course. One thing that I have always done which may or may not help some of your viewers. When I am pulling something out it tends to be a small tree or a fence post and I am using a basic tow strap. What I have always done is to put the rope through the canter of my spare tire fairly close to the end where my target is. This way if the rope comes loose from the tree or post, it tends to get wrapped around the tire instead of flying at my truck. By the way my truck does have a dual coil spring mount for the hitch which absorbs the sudden impact of a tow. Thanks again!

[@MadMatt4WD]

Thats an interesting idea.

[@shanevonharten3100]

The tether is a great idea it just wasn't thought out properly. With hindsight it needs to be stronger to withstand the forces stored in the recovery strap and much longer to allow ample room to be affective. Look forward to seeing the updated version.👍

[@anthonylongdon1649]

Hi watching this in my view & I'm sure you must have taken this into account the fuse link should be on the tether with the weighted air bags attached to that so when it does fail it's ground to the weight reducing it's energy

[@MadMatt4WD]

I can't see the tether having enough weight to cause a problem.

[@georgesimmons2946]

Well, the moral of this test for me is the 9000kg snatch strap is far to light. I know you guys said use items rated for your vehicle, but after watching this test 9000kg strap is not up to the loads. My snatch strap kit is rated to 13,000kg and I only have done 3 recoveries, my heavy recovery took 2 goes, so still good for another 6 recoveries. I had to snatch out a heavy 79 series LC and first go hit it very hard, and it just sprung my back, not damage to the strap, second go out it came, so higher rated snatch strap is for me the way to go.

[@MadMatt4WD]

Interesting but you have not understood how a snatch strap works when doing a Kinetic energy recovery. Also the purpose of this video is not to teach the finer points of a snatch recovery but to highlight the dangers.

[@willierule3744]

It looks to me that by the time the strap fails it has already stretched to the point where when it does fail you don't have to travel any further to make that other safety strap snap my thought would be if you add another 5 or 6 ft to the little safety strap then your big strap isn't stretch far enough for it to run right through that little safety strap I think a good 8 to 10 ft would be sufficient amount of length to stop the strap from coiling off the vehicle and smashing into a vehicle being pulled

That's what we're thinking as well.

As a design engineer the tether missed the 30% factor... The max stretch of the snatch strap +30% more (~1.5meters + 30%+ 1.94 meters roughly) so the tether should be around 1.9meters. Keep in mind this is not accounting for the power of the recoil. Over all good idea of the tether but falls short in design. Good video. You got me from Matts Offroad recovery channel

[@MadMatt4WD]

Thanks and welcome. I agree it’s a poor design

[@ppx4243]

Be worth testing a longer very elastic tether

[@MadMatt4WD]

I think the tether would perform far better if it was elastic.. if your main snatch strap has a stretch of 2m, I think you need a tether that stretches to at least that, and probably double that would make it most effective

[@JeffZaiham]

Great video Matt, I'm a 4x4 enthusiast and trainer I'm Malaysia and I'm constantly searching for better methods of safe recovery. My comment on the test itself relates back to the product being tested. Yes the tether failed due to flaws in design and the loads overlooked. In retrospect, the test due load the products beyond the limits of the ratings, but that is often try with every recovery scenario. Looking at the weakest point along the whole chain, the strap itself proved to be that as per intended and designed. I was looking for methods to secure the recovery points and accessories attached as they are the potential missiles that can hurt someone. Would you have any ideas on that, like using a briddle to halve the loads of recovery points, bridle line as fuse etc. Great job on this BTW.

[@MadMatt4WD]

Hi Jeff. i like bridles for sure and i also like suitable recovery points. I'm a little cautious around the idea of rated recovery points in that the can provide a false sense of security. It comes down to a rated point has to be fitted to a non rated chassis so my question is what is rated? Is the the complete recovery system or just the bit of steel that gets bolted to the chassis. Search my playlists for other work I've done that you may find helpful and interesting. I'm happy for you to use this content in your training if it's helpful.

[@dezzad1998]

Hi Matt and Jeff. Firstly great vid very informative I'm new to off roading however I'm owner operator of a tilt tray aassisted with installing wire rope barriers on the freeways in Perth. Which gives me an idea for a tether on the wire rope system they feed the 20mm wire through a swaged loop in 10mm wire which is anchored the concrete footing. The theory is that the larger wire gets tangled by the looped wire slowing and sometimes stopping the highly tensioned larger from being missile. So I wonder if attaching a spare strap either snatch or tow of a shorter length or double through shackle, giving us 2 loops to work with 1 close and 2nd towards the middle and still use a damper or 2. I hope this helps.

[@neitzsche5150]

Excellent video, Matt. Your test confirms why it is vitally important to load the KERR slowly, allowing the rope to gradually absorb the high levels of kinetic energy associated with this procedure. Also, you did a great job detailing the proper tow hitches to use. Many people are unaware of the dangers of using tow hooks or even attaching ropes to their bumpers!

I also agree the tether should be shock absorbing. ? If it should be tied or anchored separate from the two anchor points as a better catch (since you can't stop fast enough to keep from breaking it). Climbers use it (second anchor) for static climbs. With a moving vehicle that energy has to absorbed somewhere (when strap fails). Appreciate the demo. Has me thinking more on it.

[@craigquann]

Thats an idea. Basically built in sand bags....

[@dachet10]

The big risk is usually bits coming adrift during snatch strap recovery. I have had a recovery point come off a vehicle and hit bull bar then plough through the grille and radiator. The safest recovery is not winching as the steel rope is also elastic and can cut legs, arms or even bodies in half. Safest is chain as no stretch. If it breaks it will just fall to the ground. Best thing to happen in this arena in many years is the soft shackle!

[@MadMatt4WD]

Bang on but rather than chain we use synthetic rope. It light strong and falls to the ground as well.

[@Bread996]

I’ve never seen any evidence of anybody being “cut in half” by a steel winch rope. It will bruise, but not cut flesh. It’s a myth.

[@CurmudgeonExtraordinaire]

MANY years ago, we did not have tow straps (much less *snatch straps*) and we used chains for towing a disabled vehicle or for pulling it out of the mud if it was stuck. As such, if you took up the slack too abruptly, you ended up with quite a bit of jerk, possibly damaging both vehicles. I've seen an old tire used as a shock absorber of sorts, kind of like how they use one between the cable of a crane and a wrecking ball during building demolition. Chain has no give to it, so if you are towing someone and they don't constantly keep up the slack in the chain, you end up with a lot of jerking every time the slack gets taken up. With a tire added to it, you don't get jerked as much. Of course, the tires that were being used were a lot narrower than what you see on most off-road vehicles these days.

[@MadMatt4WD]

I have seen that. But yes there is a big difference between a tow and a kinetic recovery

[@CurmudgeonExtraordinaire]

@@MadMatt4WD -- Yeah, back then we didn't even have the concept of kinetic recovery straps / ropes. Vehicles that had winches tended to be ones that had PTOs instead of electric winches. Of course, there was always plenty of trees that you could use as an anchor point along with a farm jack and sufficient length of chain. Things have changed a lot over the last 50+ years...

[@MadMatt4WD]

That they have

[@seankelly353]

My 2 cents on kinetic straps and safely using them . Now commen sense IS Required! At times of sketchy recoverys I have attached a second strap looped a bit loosely around the center of snatch strap being used and anchored to a tree/ other vehicle what have you that way you can catch any failed strap or flying vehicle parts. Anyhow great video awsome information!! Stay safe out there and enjoy!!!

[@MeetingManagement]

They need to sow the tether to the snatch strap the other direction when sowing it to the body side of the snatch strap. That way when the snatch strap breaks, the part of the snatch strap that is flying backwords will work against the stitching. And also, you are correct. The tether needs to be a little longer.

[@SarasotaTim]

At the end of the video talking about walking around in the big hole hahaha In a situation where your stuck you just do what you can. But try and be calm and think logically. Then go slow even if you have to snatch 4-5 times. NEVER floor it on the first time. Great information in the video 🤙 😎 Cheers from south Florida USA 🇺🇸

[@MadMatt4WD]

Yep. :)

[@radracer4011]

My suggestion, combine the 2. Use the weighted bag, but tether it to the vehicle. One at each end at about the 3rd points, with some weight to help absorb the recoil. It'll weigh down the strap, and, being tethered to the vehicle, won't go flying back to the other end as a projectile. And since it isn't "fixed" it'll hopefully slide along the strap some if you reach the end of the tether.

[@MadMatt4WD]

Thats an interesting idea.

Safety tether should be 1/3 the length of the snatch strap, with folded loops held together with zip ties. -Lessons learned from high power rocket recovery. You want that energy dissipation stretched out over time through the series of zip ties snapping, before loading what's left into the tether.

[@MadMatt4WD]

Very cool idea

[@Birdgyver]

Hi. I'm not an engineer and I don't have a degree or anything, and I have never done a recovery, but I am a safety freak. When I first seen this video and what you wanted to accomplish, I immediately knew what was going to happened. I think that the safety strap sould be ?x more than the recovery rope/strap. The same concept that you had when you connected the strap to your vehicle. So if the rope/strap fails at 9,000 units, then the safety should fail at 11,000 units, and for it to be long enough for you/the driver, knows when it fails so that they can stop in time. This is just my own opinion.

[@MadMatt4WD]

Yeah when I first saw the design I didn’t think it would work either. I think a fall arrest type design is what’s needed.

[@russellwolter5153]

My opinion is slightly different than yours of the tether. I think the tether is there to reduce to slingshot effect upon failure. If you do the experiment with and without the tether and focus your results on the speed of snap back. Great content Matt.

fold the tether and sew it together, like a shok cord for climbing, it takes so much force to break the threads, that would absorb energy, then the strap taking the load and breaking would absorb the rest

[@MadMatt4WD]

I agree

[@thomaskiger6960]

I was a test engineer in the forklift industry. Have experience using load cell.. it takes expensive equipment to do that kind of testing. I agree they should have a three meter tether with folds sown in to make it about a meter long. Wonder if some kind of parachute attached after fuse would slow down strap.

[@wirebrush]

My thought exactly. Tether should be just like the tethers used for fall arresting harnesses. It should be engineered to absorb a lot of energy quickly.

[@garyp.7501]

Wow! Way cool! Thank you for doing this!... Nice to see that the bow shackle held and that I should use more than one air drag and weight it. If they really wanted that strap to stop the end from hitting the other end, you'd length it. As the strap breaks at the hitch, you'd want enough strap that the broken piece can get almost back to the anchor (the tree) at which point the catch strap would start to pull it back forward. But when you continue driving forward, it breaks, but this time the amount of energy is way less. You'd only need enough strength to survive the pull forward as the main strap changes direction, but not as much as the original strap because we are going to load it back up, and we want the catch strap to break without a huge load on it. Still though that would be a lot of lose strap hanging around as you would need this amount of strap on both ends. And in a successful recovery you are going to be dragging the strap along the ground. The solution is probably to sew the catch strap to the main strap really lightly. With these stitches expected to fail as the truck moves forward and the main strap moves back to the tree. PS I just ordered a second ARB recovery damper. While 3 may be perfect, two seemed to do close enough to what I need.

@@MadMatt4WD oh yeah, you'd want to sew loops of the catch strap to the main strap so under normal stretch, the stitching wouldn't be stressed.

[@josephburkhalter5105]

everyone commenting seems to think it’ OK to destroy a tether strap. it’d additional cost. probably requires replacing the rope. why not think in terms of using a much higher rated strap or rope in the first place and not use a pulling item at the top limit of it’s capacity rating. A recovery pro probably does not want to destroy his equipment on a single recovery. how about putting about 20 ft of chain behind the pulling vehicle, then your snatch rope. you already have a few feet of chain attaching the rope to the stuck vehicle. put your tether strap between the chain and snatch rope with a lot of slack. the tether fails, saves the very expensive stretch rope. The tether could be just 8-10;ft of 5/8 3 strand nylon and it’s being asked to stop a piece of flying rope and not a flying shackle. nylon is quire strong and quite inexpensive. Jerk ropes and straps are quite expensive. Great videos. Great subjects. JoeB

[@MadMatt4WD]

I think you may have misunderstood the purpose of this video. We wanted to see if this tether idea would work as per it’s supposed design. It obviously did not.

[@r1chardarcher]

The need is to dissipate the energy of the strap. The tether will have done a little bit of that as it tore through the stitching, but obviously not enough. Your talk about the free length of the tether is definitely true, where the strap has extended 1.5m, there needs to be an ability to capture that 1.5m, as well as the number of metres the vehicle will have travelled once the strap has failed. My thoughts are that the energy dissipation could be achieved by something a bit like a fall arrest strap used for working at heights. Quite a number of folds of the tether material stitched together so that the tearing of the stitching assists in dissipating the energy. As we are generally talking of attachment points failing rather than the strap itself as per these tests, the tether can be through the eye of the strap rather than stitched to the strap, as that stitching is what failed. The folded and stitched part of the energy dissipation pack also allows for more tether length in a compact package. Hmmm

[@MadMatt4WD]

good thoughts there

[@tano1747]

Another challenge for the tether is that the load is applied to it SUDDENLY. At minimum this doubles the applied load. The tether would need to be 1) longer, sufficient to very generously cover vehicle stopping distance, stretch in the main strap, and safety factor, and it would need to be 2) very elastic, so it can decelerate the fast moving failed end of the strap gently ... this means it has to decelerate it over a long distance. Something like an elastic bungee rope would be a better tether than a rigid strap, i would think.

[@MadMatt4WD]

Good thoughts. I think the elasticity would just keep bouncing it. I think a fall arrest system type design would work.

[@bobgrauer]

Almost 50 years ago we didn't have the ropes you have today, but we did do something quite similar. We used 2 chains and a car tire. We could pullout farm tractors and combines with a standard 4 wheel drive P/U.

Welcome. In your case you are not performing a kinetic recovery but rather a tow recovery, 2 very different proceedures.

[@ridermak4111]

Another idea for a safety tether that would need testing. This could be added to any snatch strap or even maybe to a winch cable. A length of rope or strap that is about 40’ longer than the snatch strap, that is, 20’ extra length for each end that is held in a Z-folded bunch by a Velcro loop, the end secured to a different spot on the vehicle than the snatch strap. After one end is attached, the rest is spiraled around the snatch strap 8 or 10 or 12 times along the full length and then secured to the other vehicle. Granted, it would not be super quick to set up, but being wrapped around many times I believe would entangle and arrest the speed and distance of a broken strap/hard parts. The extra 20’ (or maybe just 10’) would deploy from the Velcro loop with enough slack to not get broken itself but short enough to catch the flying parts. ........ I hope this description isn’t totally confusing but I think the spiral entanglement has merit. PS I don’t think the recoil of the broken snatch strap broke the tether of the original design/video. I think the rapidly moving vehicle reached the end of the short tether.

[@MadMatt4WD]

I think Ditch Hitch has a system as you describe. We didn't have great slow mo but it wasn't the vehicle speed that broke it when we watched it back frame by frame. kzbin.info/www/bejne/fqbSmZxjbsipbpI

[@donhappel9928]

late to the party, but aside from the fall arresting set-ups many have suggested, perhaps using something akin to a rappelling brake rack? Secure it to the vehicle and run the tether through it with a free end. In a failure the drag of the broken strap pulling the tether through the rack would slow it over time and you don't have to worry about the vehicle running on and breaking the tether. Not sure if this would work based on the energy involved or how practical it would be in actual use but could potentially work.

[@MadMatt4WD]

could you please link a video with this system.

[@donhappel9928]

@@MadMatt4WD kzbin.info/www/bejne/gaTPZ4ibZ8uKjdk You wouldn't need all the features of a rappelling rack, but as you can see the friction to slow the rope is simply caused by weaving through the bars. As they slide they get tighter and bind, bringing the rope to a full stop. For a tether strap I'd picture it more as a non-sliding set of bars that still open to make it easy to insert the tether through them. The rack is anchored to the truck and the loose end of the tether fed through it with only enough slack to allow for the stretch of the recovery strap and the remainder left free. In a failure the strap snaps back but has to pull the free end of the tether through the rack where the friction slows it. Would take some testing to ensure the tether was sewn well enough to the strap that it didn't just tear off and that there was enough length to the tether to slow the strap before it pulled all the way through. You would still get some snap back from the strap from the drag of the rack on the tether but substantially less than it simply parting. And having the free end pull out of the rack means you don't have to worry about trying to stop the vehicle in a short distance as the tether would simple pull through at a fixed resistance. Could it be designed to provide enough resistance to slow a broken strap without being too cumbersome or expensive to use? Not sure. Just an idea that would need more exploring to really verify.

[@MadMatt4WD]

Thanks Don, That's interesting. I wonder if heat would be an issue?

[@hitchpost5822]

I guess you make some good points, the tether need to be redesigned but I have never seen anyone use a strap with that much vehicle acceleration seems like operator error to me.

[@jvalentine8376]

The thing that strikes me with many 4x4 owners is you see someone ripping away with a snatch strap until it breaks putting a lot of stress on their vehicle and the other vehicle also , when all along they had a big fat winch under the bull bar . Yeah , "it's quick an easy until it fails quickly and easily ". To make the strap safer add air brakes . Small parachutes attached along the strap .

[@MadMatt4WD]

I totally agree. Way to fast to grab the snatchy.

[@contemporaryprimitiveman3469]

Years ago I saw a farmer try to pull a stick combine with a 1 ton ranch truck. He couldn’t reach the truck with strap alone so he used a chain against everyone’s advice. The chain failed at full load and rocketed to the truck, split the tailgate like an axe, took the top off a diesel tender pump tank and went through the back cab glass and out the front. Nobody injured but some nerves were jangled!

[@MadMatt4WD]

Yeah wow.

[@EronIler]

Try a tether 15’ long with a loop that slides over the snatch line and secures to the vehicle at a second point, a nearby tree, dirt bag or water anchor. When it fails the snatch line will fly around the loop to stop it but not directly back through it. It will then drag the loop with the vehicle. The tether could be made from a winch rope with a couple bolin knots. This will give it plenty of strength for a low investment. You could make a few from old winch ropes.

[@motorvatorv888]

Fascinating stuff. I also have seen enough pictures of pierced 4x4s to find snatch recoveries scary. Much of the military forbids them unless the vehicles are armoured. Even then, winching is always preferred. Back to the tether; it’s only going to work if it’s a similar strength to the original strap. My thinking: kinetic energy from vehicle->potential energy in strap as vehicle extends strap. Fuse fails. The potential energy is released becoming kinetic energy of the free end strap. It’s the same amount of energy. So to capture free end and store its energy, you need another 9T strap. And you’ve got a tow vehicle that’s still moving to deal with too. The only way to get out of this bind is to create big losses, ie create a good damper/s that dissipates as much energy as possible from the flying strap. And we’re back at the first part of the video.

[@MadMatt4WD]

Great comment. I’ve thought some type of fall arrest design with layered stitching. But yes kinetic recovery is my last resort.

[@Governor_William_J_Lepetomane]

Great video. The safety tethers would perform much better if they were kinetic in design like a kinetic recovery rope. All they need to do is reduce the amount of force in the tow strap before the tether fails, and that would be enough to ensure that the tow strap doesn't kill anyone.

[@MadMatt4WD]

Maybe that would work. It might just make the strap bounce as such.

[@biggs8729]

The tether strap, not completely pointless. If you really did a slow-motion view of that I would imagine the tether decelerated the strap a bit before it broke. It did return with quite a bit of force, but if you did the test again without the tether I think it would be a lot more violent. Hard to tell without a true high-speed camera. Absolutely love the overall testing. I think it’s awesome that you guys are working with the strap company to make it better. Thank you.

[@MadMatt4WD]

Glad to help Dan. Make sure you use the correctly rated strap for the job

[@timgilbert3051]

My ideas would be: 1) To make the tether quite a bit longer so that by the time it engages, the broken snatch strap is already rebounded to its initial length and all the tether has to do is arrest the mass of the tether in flight instead of the tensile force of the stretched strap. 2) To make the tether part elastic too so it absorbs the energy in the tether instead of just ripping out the stitching. 3) to make the tether be a bit stronger (maybe 1/4 to 1/3 of the breaking force of the main strap). Because of the fuse, we know that the force the tether is faced with is the full breaking limit of the strap, which is considerable. And to be safe, we need turn that energy into heat rather than momentum. A weak tether can't convert much energy into heat before it breaks.

[@MadMatt4WD]

Totally agree

[@scotttaylor3872]

The tether needs to come into play AFTER the snatch has mostly returned to its unstretched/unloaded condition. That means the tether needs to be much longer. If the tether is now not trying to arrest the recoiling snatch strap forces, the tether can then be designed to absorb the inertial forces of the flying snatch strap. That's what air dampers do, much less energy to deal with. To manage the longer tether straps, I suggest that the tether be coiled with some sacrificial ties (e.g. light duty zip ties) that break away during deployment. The original concept is good, just needs a tweek.

[@lovemypajero]

Very informative video. With the recovery strap with the tether I think it would be better that the tether is the same size as the main strap 3m in length but folded in the last meter and a little stitch or something similar to keep it there. If your strap breaks at the fuse and recoils you have the 3m extra with 9t load to pull up in. You will either feel or hear it break so you have the length to stop saving a lot of damage.

[@MadMatt4WD]

I think this sort of idea is the solution. It’s how a fall arrest system works

[@jimfrancis]

I fully believe that you'd have a completely different reaction to the strap, if the tether were attached to the strap at the 1/3rd mark. It seems that the danger spot is at the fuse point, when it breaks, and the original tether didn't change that spot. Moving the tether attach point back to the 1/3rd mark would add much more stopping power to the tether, rather than being so close to the initial break point inertia. Use a whip for example, the shorter the whip, the less inertia at the tip, lengthen the tether to shorten the whip length from 9meters to 3meters, the failed strap should have less inertia (and danger).

[@MadMatt4WD]

thats an idea worth exploring

[@bmd1825]

@ Jim Francis - Ditto....failure repeatedly occurs at the fused/ stitched point. Great point to move down 1/3 of the distance and see the results.

[@gold5th]

Downside to that is typically stitching doesn't stretch.. so you'd have a 4-5" section that has no stretch in the mid working section of the strap and after repeated hits you might start popping stitches.

[@dc85337]

Here's one for you to try. Use a standard strap then put a rope with an eye just big enough to go around the strap and is 75% the length of the strap. The rope is put on 50% of the length to the vehicle. The rope eye can be braded or just an knot. Type of eye is un-important. When the tether fails, the vehicle is going forward for a bit and drag the rope that has an eye around the middle of the strap and will drag along the rope and prevent the end of the broken tether from going back and "hitting the tree".

[@MadMatt4WD]

I can’t see that working but it’s an interesting idea.

[@ericperry5998]

First off great video lots of useful info. Secondly I’ve seen these bow shackles fail mostly due to the fact they improperly used or have just been mistreated. (Another video idea if not already done.) I no longer leave bow shackles on the exterior of my vehicle to get abused on rocks and so forth after seeing some of these issues. Actually I leave none except for the winch line and hook outside of the vehicle. As far as the tethered strap goes I like the idea another viewer had on using the idea of a shock absorber from a safety lanyard. Those things are designed for up to 5k lbs or 2267 kgs.

[@marceld6061]

This is an older video at this point but my thought is this: The tether should be elastic. 1) When the strap breaks, the elastic will stretch to absorb the energy from the broken strap. 2) it should have enough stretch to allow the tow vehicle to come to a stop before breaking. Your thoughts?

[@MadMatt4WD]

I’ve wondered the same and would love to see it tested out. I don’t have the ability to do that.

[@rthinds]

The breaking of the snatch strap is shock-loading the tether. None of the tether joints (sewing) were made for shock-loading, especially with the forces depicted in the video. Listen to the sound of that thing breaking at 10:30. Wow!

[@MadMatt4WD]

Yeah the tether never had a chance.

[@JuskoLord247]

The tether is a very great idea but if it is stretchable like the kinetic rope, it wouldn't snap because it will stretch further and absorb the energy before the time you stop pulling.

[@MadMatt4WD]

That’s an interesting idea but I’m not sure it would work.

[@josephbelaj3660]

Great job you are doing out there. My observations are...1. The tree is stationary and not going to move within the design perimeters of the strap. 2. The vehicle can apply more force / stretch to the snatch strap because the load [tree] is not moving and the design perimeters were exceeded. 3. If the recovery included two vehicles, one stuck in muck and one pulling, the design of the equipment would most likely work as designed. 4. The experiment with the tree took the straps past their designed capability... 5. Yes if you had a load cell to measure the force involved, it would show that the recovery equipment held up way beyond its loading design. Thank you for your site. 2011 AEV RUBICON

[@MadMatt4WD]

Thanks mate greatly appreciated. I disagree with your assessment because I’ve done recovery where the stick vehicle didn’t move when hit. What I’m doing it providing a consistent anchor. Also I had a fuse on the vehicle end to ensure I had a controlled fail to see if the tether worked.
