Back in the 80's I was in the airborne infantry and a few of us were offered a chance to cross train in vehicle recovery. It was a three week class and I learned a lot about recovering every type of vehicle you can imagine, and in every type of situation you can imagine. The one thing that stuck out that I will NEVER forget, was seeing the damage done to an M88 tank retriever when it's main winch line broke. The main winch is a 70 TON single line pull, and I believe the cable was 1.5 inches and I think there was 300 or maybe 400 feet of it. When the line snapped, it came right back and hit the M88 head on like a punch, and it knocked a hole RIGHT THROUGH SEVERAL INCHES OF STEEL BULK HEAD. You could see where it actually melted the steel as it forced its way through. No one was hurt, but it scared the crap out of every man there. The instructor said this is what happens when you don't do the math when figuring mire factors, block and tackle friction factors, knowing real vehicle weight, and enough pulling power to winch every sick whore in the world off her piss pot at the same time. Seeing that made me even nervous to pull too hard on my boot laces when tying them up. When we winch now, my pucker factor is always so tight you couldn't pound a pin up my ass with a jackhammer. I really know what can happen and it's scary. Whether or not these tests are real world, the damage a broke wire rope will do, is real world. Keep up the great work.

WELL DONE LADS! No joke this is the kind of thing that makes a difference and will help many people. There's no way to know all the people who will avoid injury but we can confidently say it will be more than a few. I know I've changed the way I think about metal cables now.

@@hardrockuniversity7283 i agree the results would be different but not so much from the elasticity of the strap but the fact there is almost no weight to the strap therefore less resistance to aide in slowing down the cable as they look to be winch extension straps and they are designed to have minimal to no stretch. if they replaced the strap with heavy cable the initial speed and force of the recoiling cable would be much the same but it would have more of a wiping motion as the heavier cable would not have as much energy stored causing it to act as a dampener so it is unlikely that it would recoil as far and bunch up as much at the end.

One trick I learned was that when dredging to undermine a boulder, you keep contact with it (usually with your head) while keeping your legs and arms as far away as possible.

Hi Ronny, I witnessed a guy in a Unimog try to pull out a tree stump once with a winch and steel cable, the bloody thing broke and sliced though the passenger side of the cab. This shit is very real. Stay safe peeps.

Thanks for a great and informative video. I had been using a steel cable to help drop large tree's with my tractor. I knew about the risk of possible snap-back if some thing broke, but had never witnessed it first hand or on video. Very scary! Glad I'm done with that job.

Great documentary. Thank you for the information.

Love these videos!!! Being an x tow truck operator I know what can happen when operators don't listen to the cable. You can hear the tension rise and if you ignore it people can get hurt. Great series of videos beginning with the puling on the trailer balls. great to see the dangers and knowing will keep more people safe. Keep them coming!!!!!

1985 I was in the hospital and met a bloke on the ward who cleared forests. He was a partner in the company that removed the stumps. They were using a ww2 tank recovery vehicle to deliver the dozer and also as an anchor in an elaborate multi pull set up delivering close on 100 tonnes of pull. One of the lines caught him in the thigh and shattered his femur. Luckily he was close to the end of the lines reach and it was only a minor line. Though it also took the cab door apart and ripped the seat open. He said it was a miracle because he was standing up leaning out the window waiting for it to get exciting, then the door glass shattered and he shouted: "that was lucky". Then he realised he'd been hit. His journey to the ambulance was on a digger bucket full of loose soil and branches. They tried it empty but the ride was to rough for him. A fantastic storyteller, very descriptive, it was like being there.

Steel is the industry standard for people who know how to use it & look after it under working conditions whereas dyneema is more suited to the variable conditions seen whilst offroad & general public use where there's probably no idea of how to even do a cable safety inspection or routine maintenance. Think about how many powdery dry cables with visible rust you see hanging out of bullbars & that's an idea of where cable safety standards are at.

@gaj5701

To clarify, as you basically agree with my point, steel cable is used throughout industry for heavy rigging & is subject, in most cases to safety checks & maintenance schedules which unquestionably has an impact on the safety of it's use. Winches fitted to private vehicles aren't subject to this kind of scrutiny, & whilst you may have been on top of checking the condition of your steel cable I can almost guarantee the average offroader doesn't look at them from one year to the next despite having bashed it through rivers, deserts & beaches. For that reason alone dyneema is a safer option for offroaders as it doesn't require any specialist knowledge beyond knowing how to fill a bucket with soapy water every now & then. Yes, it's lighter & easy to splice etc. but I was talking purely from a safety point of view. Hope thats clearer now 👍

Great work Mr. Dahl. I agree with the posts that your overall point was to demonstrate the dangers of failed cable & rope. I just installed my first winch about a month ago and honestly, I'm going to afraid to use it when I need to!

After many years of rigging on cranes, bull rigging never broke a cable. But broke chains, deformed shackles, ever broke a sling, (nylon) but stretched them enough to expose red thread. Shreded a few eyes on slings (nylon). We always found what we hoped were safe locations to stand. Haha knowing a snapped cable could go any where, which in lifts and pulls a broken cable was least of issues.

oops I gave a thumb down, as you know crane systems use block purchase in their systems. there are heavier loads through more blocks with better results. weight is weight so why is it that a 5K cable will break @say 7K with direct pull, but when the same cable is run through a 4 block purchase it will not break the same cable?

you also have the elasticity of the purple strap adding to the winch line

Despite the contradicting comments (and they may be right), the value of this video is, I think, priceless. Good on ya.

Hi, the elephant in the video is that on cable and straps (excluding ropes), a single standard correctly weighted winch dampener / blankets do not work. I reviewed 6 years of testing videos online and not one was able to show any safety effect on cables or straps. In some they made it worse by adding to the missile. The 4wd industry needs to stop advising that a winch dampener makes cable or straps safe. The only safe step is to stand well clear of the danger zone with cable or straps.

@@teamidris In the operation of a winch there are videos by Ronny Dahl on here that explain all the steps to use a winch safely. I agree 100% with him. We hold classes every summer teaching people. Not just using them but all the different ways you can use them. No offense to you sir but I must disagree with you 100% In these classes and on our overlanding trip with our group my girlfriend is a very good person to have. She is an emergency room physician. She teaches short courses on First Aid. As part of that she shows injuries that came in from winching accidents from people who allowed her to photograph them for her classes. There is NO more important part than to have winching blankets on AND proper places to stand while doing it. How much weight you put in the bags is up to you. At the beginning of the class we show winches snapping without a winch bag. You can EASILY bust your windshield without a winch bag or worse, hurt someone else! It doesn't have to be the line itself. It can hit something and cause injury by the shrapnel coming off it. I have a line snap with a winch blanket. The tension causes it to go straight back to the winch. Lets say my winch bag is 5 feet from the tie off point. Once that winch travels that distance the slack in that line is gone. It had 5 feet non impeded room. Once that slack is gone it hits the drag of the winch blanket and stops it. Now does it stop it at five feet on the inch? No. But it does the job. That broken line takes on the weight of that winch bag and stops it. BUT that is only half the safety you get from it. The winch bag holds the line down. It is weighing that line down. You see it sag when you put the bag on it. This is key because it holds the line down low to the ground. Lets say you have a bag on the line and it snaps. 1. The weight of the bag instantly begins pulling the line to the ground. That keeps the line down low to limit places that line can go when it takes off. 2. This is the second reason why you use more than one winch blanket on a long winch pull. It decreases the danger area by a LARGE margin. 3. Most people or a big percentage of people use "line" and not cable. Line is much safer to use. Why? Momentum is weight times speed. The line weighs much less per foot than cable does. That makes it MUCH easier for a winch bag to stop it. This is where you get into the debate of how much weight you put in your winch bag. 4. For ANYBODY who wants a good clear demonstration on proper use can pull up Ronny Dahl video on here "Winching Techniques Beginners To Advanced." It's only 15 minutes long BUT EVERYBODY should watch it! He will show you the PROPER way to use a winch. I have thought about taking her photographs and making a video of them on here. She has three photographs of legs that were amputated. The worst accident struck an 11 year old boy in the head and killed him! He died instantly! PLEASE watch his video!!

It's not that simple... You're failing to differentiate between kinetic energy and momentum... Momentum is conserved, kinetic energy is not... The movies might make you think that when a person is hit with a .45 round (or even a .44 mag), it knocks the person back a good ways... The fact of the matter is that it doesn't... The momentum that the person gets hit experiences is the same momentum that the shooter experiences... But if people got hit in the movies and just dropped / slumped down like is more likely to occur in real life, it would make for a boring movie and the special effects people wouldn't be making as much money... :)

I own and operate a tilt slide tow truck. I used to run steel winch cable on my 15,000Lb winch until one day during a bogged vehicle recovery the winch cable snapped and almost took my head off as it flew past as I was operating the winch control from the side of the truck. The cable smashed into the steel head board smashing it up requiring a new one to be made and fitted. That was about 5 years ago. I switched to Dyneema rope after that now I'd never ever go back to wire cable ever again. I have been using rope ever since and had 2 failures and can say just as you demonstrated that it will still recoil but no where near as much as steel cable. Both times the ope hit the head board and there was no damage to even the painted surface.

Ronny and the gang just used the winch stuff as a exuse to dozer the car XD

Respect for your team and may those dummies rest in pieces 👍

This is awesome content for safety purposes, Thankyou for doing this!

The common dynema sk75 rope has a 3% stretch according to specs. That combined with its lighter weight means less stored energy. Less energy stored in the system is always better. It would be intersting to hear the testers opinion on if the dynema rope was easier to break then the steel cable. Was it more sensitive to being cut where it touches an edge. It would have been interesting to see if adding a thimble in the ends of the winch rope would have make it significantly stronger. Dynema rope for the win in my books.

Make sure you're not sitting in your truck, while it is run over by a bulldozer. Stand to the side.

Great video, a reminder to all about the dangers of winching and what can happen if the wire or rope break.

We didn't have time to recover the cables & anchors & cut the cables which flew faster than the eye could follow well over 100 meters. A large water spout touched down and moved parallel to us as the last cable was cut. It was quite exciting... But the energy is stored in the steel as it twists & stretches.

We are always making sure people stand back anyway, but this really hits home how lethal steel can be. Im not going to let anyone use steel cable in our group after seeing this. Not unless its for some really simple gentle winch. Ive shared the video on our facebook group too as a reminder. Thanks for taking the time to create this, it mustve been great fun to make.

Great test and demonstration! My only issue is the amount of straps that were used, this adds a tremendous amount of elasticity. Yes steel cables have some elasticity and there is snap back when it breaks, but I feel that the amount of purple straps used doesn't depict a more common winching situation. Great video tho!

the belts stores much less energy than a steel cable, I used to work on the replacement of steel elevator cables, when replacing, we used huge brakes that turned red hot to slowly discharge the energy accumulated in these cables

You are absolutely right. That purple nylon strap can elongate massively before failure, meaning that it can store huge amounts of energy. I expect the vast majority of energy released in this demonstration came from the nylon rather than the steel.

If not careful it don't matter cable,rope,or strap it will kill. I have an uncle living with that memory for the last 25 to 35 years now

😱! Very educational with a brilliant end! Thank you lads 🙌🥇

I'd like to thank you so much for all your hard work and testing to show all of us using winches just how dangerous it can really be from Oklahoma thanks again.

That hit so hard it moved the steering wheel to wrong side of the car! You should see what 1.5 inch cable does when it snaps.

The SES had us winching with the bonnet open. Bad for vis, good for your face. Either way, I duck under the dash and have a bo peep every now and then.

This has to be the best proof ever filmed on the dangers of Winches, The most important point here is never run your cable over any object as it will cut the cable, And it also ends the myth about rope falling to the ground, at the end of the day, Always inspect your ropes wire or Rope they both travel at about 800 feet per second and both will kill if a person stands any where near the danger zone, Well done Ronnie this must be your best public information film yet, Big thumbs up.

What a rad video! Thanks guys!

About the synthetic winch cable.... I would love to see the same test again but with only similar synthetic connectors and cables. If you watch you can see the tree strap strech (15:50) and alone could have made the cable fly back at the dozer and I'm guessing that there was a lot of other materials (like straps) in between the tree and bulldozer. I'm not saying I think it would just drop to the ground but I would love to see the test without any variables. Even the heaviest chain connecting the dozer to the cable will introduce an incredible amount of energy into the recoil even if its not the weak point or the part that breaks. Love your videos! I watched again and you do specify that it would be more recoil than normal due to the connectors.

Yes finally someone who also sees that this video is proving only that straps stretch. That is where most of the energy in recoil is coming from that 80 meters of stretchable strap. Using the cable and only the cable is the only scientific method of testing cables or other lines. BUT VERY BIG BUTT!! this is GREAT GREAT demonstration of the dangers involved in winching, pulling and having fun off-road Despite my criticism, this is a great video and is well worth your time to watch! Well done!!

the guy on the dozer as got some nerve...I didn't see any protection except that cage.

I noticed at one point he ducks as it starts to stretch!

Back in about 1990 (not exactly sure) when I was working construction on the Gold Coast a pre-cast panel was being tensioned on a high rise in Bundall. A cable snapped, ripped up through the concrete and took a worker's foot off at the ankle. I had a mate on that job. He said it was not a pretty picture seeing all the blood, flesh, bits of smashed bone and the general panic of the workers. I was a rigger, working with cable all the time. It was a wake up call for me to always be mindful never to overload steel cable.

I was on a hotel job a couple of years ago and they had some dodgy mob post-tensioning the slabs. All their gear looked old and shit and the strands had been sitting under water for weeks because the builder was a complete numpty. They had blokes standing around all over the place. My mate and I took one look and went home for the day. Neither of us wanted to be around because if something went wrong, it was definitely going to be the messy kind of wrong.

Thanks Ronny yet another top quality video

this is the best video on the subject i've seen yet. Mythbusters did one too, but didn't load the cable to the breaking point, but rather cut the line at a strain far below the breaking rating. that video was a total dud. they tried their level best to make the subject look harmless. there have been many fatalities in high lead logging where someone caught the whip end of a broken cable and got killed. some have been cut in two. mythbusters again tried to show this wasn't possible when in fact it's highly likely. good work guys!!

Sirs, Your presentation is an essential requisite for any person using cable systems for home, recreation or commercially. The physics apply equally for nylon and other types of rope. My occupation in the logging industry deals with the dynamics you have covered on an near to constant exposure through out every day. We push the limits with cable systems that will break 1 inch and greater diameters at ease if not respected. This is a contributing factor that keeps the logging industry as the number 1 most dangerous occupation in the U.S. The load crack heard is in fact a supersonic report, not a subsonic report., as a projectile rather a bullet or a fighter jet exceeds the speed of sound @ approximately 780 ft/sec, it will make a sonic crack or boom depending on its mass. A human body has little resistance to shredded steel, resulting in gastly wounds Cable will give an advance warning of pending danger most of the time, with warning signs of audible pinging sounds , at such time one should hit the ground or hole taking cover as if under an artillery attack. You have done an excellent production in showing the dangers of tensioning cables, ropes and related rigging. Hopefully you will prevent many people from the deadly effects of said systems, not only for the implication but also as nearby observers. Keep up the good work Logger/ Timber cutter Mark

Mark Harris you are right on except the speed of sound is 1, 100 ft/sec at sea level, that's even more energy...... Good luck sir!

Great video Ronny! Very educational. I was very hesitant which winch to buy and in the end I got a synth rope given you can re-splice them. When you are 1000kms from nowhere, you want to be able to fix things easily, but the slice factor of a wire cable is toooooo crazy.

Welol done Ronny, this should be compusory viewing for off-roaders! Thanks.

My take on all of this is buy a cordless winch control. And operate it outside the arc of the cable, as there is realistically no safe place, for using either cable.

Ideally you would never put a winch line in these situations. Know the limits of the line and what you are winching. Learn how to rig properly and safely. 15 years of heavy recovery. I used a lot bigger lines than those used here. Did I have a catastrophic failure? Yes, however, it wasn't as nearly as dramatic as all this. If you rig it right and operate within safety margins, these types of things don't happen. I don't know where anyone got the idea that synthetic winch line doesn't recoil. That's simply ridiculous. Also, it should be noted that when recovering or salvaging ships, they will cut the ship in pieces using wire rope. like a band saw.

@@BamaShinesDistillery ya that's about 3:1 ratio on the winch rating which in my opinion is where it should be. Keep in mind that things that cause more resistance such as inclines and deep mud add the load weight of the vehicle being winched. The more resistance that you can remove, the better it is for ease of recovery. Having a snatch block and 50-100 foot cable to attach to anchor point can be a day saver. Let's just say that I've done this a lot and I've had some extreme recoveries under my belt. Stay safe.

I believe ALL. the male mannequins were de-nutted.

That video was worth watching if only to see the slow-motion (and the analysis) of what happens to destroy the steel cable as it passes over metal. I've always known that it can happen, but the physics of the thing slowed down like that (and good camera placement and editing) made it abundantly clear.

Thanks Ronny. Sure some of the pulls were not realistic situations BUT this video really hits home on how dangerous a winch recovery can be. I always make sure there is a safe zone. For good measure I might us go ahead a lift the hood up on my truck next time for a bit of extra safety. Those failures happen so quickly you can't react. And the line weights help but they are no guarantee.

That's one tough tree!

Awesome vid mate. Very comprehensive, I only wonder if a fourby would have the strength of the drott dozer to replicate those tests. I would be interested as well to see what the breaking strain actually was on the steel and the nylon. Cheers

I learned a lot. The rope was much safer. But definitely dangerous. I was aware that cables were dangerous, but I wasn't aware of how much. Those things can cut a person in half. I just bought a 12000 lb badlands winch. Im glad I watched this video. Thanks for sharing.

Guys used to just laugh at me when I warned them to get back away from cables. I wish they could see your video. Very good safety training vid.

Well done! However would like to have seen more attempts with the synthetic cable, to observe the potential for damage from recoil.

Even though the synthetic rope has recoil, it is in a strait line. It doesn't seem to have any whip in it.

Fantastic video Ronny! Really highlights the danger of built up energy in a cable or rope under stress. Very entertaining too! Had a good laugh!

Absolutely scary and a great reminder. Thank you. -Pidge
