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!

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 ?
@MadMatt4WD5 жыл бұрын
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.

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.

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!

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.

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

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.
@MadMatt4WD5 жыл бұрын
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.

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.

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!

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.

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.

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.

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.

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

@r1chardarcher5 жыл бұрын
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
@MadMatt4WD5 жыл бұрын

@tano17477 ай бұрын
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.

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.

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 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.

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.

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.

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.

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.
@MadMatt4WD4 жыл бұрын

@scotttaylor38728 ай бұрын
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.

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.

@jimfrancis4 жыл бұрын
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).

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".

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.
