So I watched the other video where Ronny intentionally makes the tow ball fail and my take away was that the tow ball is incredibly strong. He took a 10 meter snatch rope and got a full speed run at the tow ball with as much speed as he could and that tow ball held over and over again. He did eventually get the ball to fail, but I think it took about 4 or 5 tries hitting it with as much speed as he could. For subsequent tests, he ended up having to cut half way through the shank on the balls and they still were very strong. I’ve never subjected a vehicle to that kind of torture while trying to make a recovery, but if I did, Yes, I would use a better recovery point. Now I’m not saying that tow ball is the best place to hook to, but for the average stuck vehicle, it’s more that adequate for a recovering. Like all things, it requires a measure of common sense and if you don’t have it, I guess follow the advice in this video.

Not really, I like my truck enough that I'm never going to smash the throttle like that. Maybe somebody else will, but not me. If Ronnie would have put a forged receiver, a 2-in ball with a 1 inch shank in the back of his rig, he would have ripped the back of that Toyota off before breaking that ball. He purposely got light duty tow balls to try to prove his point. Not saying it's a bad point, just don't condemn everybody out there that drops the strap on their tow ball for a simple recovery. Not everyone is driving a dedicated off-road vehicle and sometimes you have to help the next guy with what you have.

Thanks Matt, yes I had a front tow ball on a bumper and I just needed a small tug off a flat spot to get out of the way on a busy trail when my jeep died. I had a guy freak out on me that you never use the ball. There are a few times that it is okay. If it's a simple tug where there is barely any load on it then you can go ahead and do it. In my case the tow ball was attached to the front bumper, the previous owner would use it to position an RV. But if it's in a receiver, then just pull the ball assembly and put the strap trough the pin.

Recovery points are usually for more suspect and un-rated when it comes to shock loadings. Ronny Dahl had to partially cut the towball shanks to get the towballs to fail. Effective dampeners on the ends of the strap go a long way to dissipate energy but you can remove the tow tongue, poke the snatch loop into the receiver & put the pin through it rather than over the tow ball.

So considering the dangers and such you then make a considered plan that is as safe as you can make it for the situation you’re in. Part of the process if you know you will be performing recoveries is to prepare the vehicle as best you can. There can be lots challenges at that point with the modern vehicle. So you decide whether you hook on that way. If you do I suggest you keep the recovery energy as low as you can.

I'm delighted to see you going through the details of the safety parameters involved in a pull, but I have to say, I think you missed the most critical thing: the difference between the load applied to the attachment point is orders of magnitude higher if you are pulling with a chain rather than a kinetic recovery rope or strap and you don't snug it up before starting the pull. Shock loading breaks things. Any time a pull is being done is an engineering exercise: there is a series of connections and each one must be within the safe Working Load Limit (WLL) NOT the Minimum Breaking Strength (MBS) of each of those connections. For example, not all tow balls are created equal. The ball on my truck is rated for 40,000 lbs/18,000 Kg and the hitch is stronger than that (I move house trailers). The tow ball used to pull a small utility trailer would commonly be rated for 10% of that, and wouldn't be nearly as strong as typical recovery equipment, and therefore not safe to pull from. Finally, Inspect your equipment! If it's rusty or frayed or worn or cracked, retire it before it breaks!

If you must use the towball you can wrap the end of the strap under then around the towbar and hook the loop over the towball. If the towball should by some fluke break, it will be propelled a small amount into the rear of the tow vehicle. A modern 3500kg rated 50mm towball has a shear strength well over the usual snatch strap rating. This is far stronger than using the hitch pin, because using the hitch pin this way it becomes a single shear point and is already way under towball shear strength.

If you added a grade 8 pin and solid bar insert, eventually the bolt will slice through the outer receiver, fracturing it. 13,000 single shear of a grade 2 pin, 26k double. That's a doozey of a pull.

Really appriciate your concern for safety. From a technical point of view it is not so much about single or double shear. It is about shear surface and shear strength of te material. I think that the real danger is the use of kinetic rpoes. They will introduce verry high peak loads on the recovery points. This is especially true if the vehicle doing the recovery gets some speed before the kinetic rope tightens. Land Rover recons that loads in excess of 13 metric tons may occurre in some of the recovery procedures.

A more precise way to put it wouldn't be to say that the double shear is *stronger* because it isn't, what it is, is the force being divided between the two shear points, so nominally half the force is applied over a single shear. This is important because if things aren't set up correctly, or in sub-optimal situations, such as if one hole is worn out larger than the other, it can go back to acting like a single shear joint.

Hi Matt, Its just occurred to me that you potentially have the same problem if you try and snatch recover a vehicle and trailer combination backwards using the recovery point on the back of the trailer. About the only difference I can see is that when either the towball or part of the hitch fails as you describe, it is less likely to become a projectile as it will hopefully stay locked onto the coupling on the trailer (not a risk I'm willing to take though)....

There's another reason you don't recover from a trailer though... The trailer's chassis isn't at all suitable to do a recovery from.

What you can do with your tow ball is directly tied to it's rating. But in the case of recovery you do not want your ball to be anywhere near the weakest link. On the other hand you could have a sold hitch and ball rated for 20,000lb. Unlikely that is what most people would have on their small 4x4 though.

The problem is the towball hitch you are using is a two tonne limit. The potential for a tow is in excess of two tons. The Jerk component is way higher, you need to highlight this point. The ball breaking is caused by not being tightened properly or has been badly abused. it is way stronger than you are suggesting, human error is probably the primary failure in most cases.

I had heard about this issue before and told him it ain’t made for winching out you need a D shackle type for that use. He was surprised and had not heard that before. I think people commonly make this mistake as we see the rating and think it is plenty.

@@MadMatt4WD I should state that I do not drive a small offroad vehicle. I drive a heavy duty diesel truck. My hitch receiver is rated at 20k lbs and is mounted to my chassis with 3-4" welds and 3 1/2" diameter bolts on each side. My chassis is reinforced for towing and is incredibly strong. Most offroad vehicles do not have a hitch receiver anywhere near that strong and honestly should not pull on it as it can bend their chassis. If you are having to yank on a stuck vehicle, it would be best to use something that is directly inline with either side of the frame of your chassis because as you said, force travels in a straight line. I should also state that in most situations, there are safer options than using a hitch and ball. Using a d-ring or even a pintle hook is safer because it does not allow the strap to come off in any direction. The slightest bit of slack and a bump can cause that strap to move from the shaft of the ball and can become dangerous if the strap slips off. If you have a truck that is strong enough to pull most vehicles including 18 wheelers out of the mud without having to yank on them, the hitch is fine. You just have to use the right tool for the job and some common sense. If you have to back up and yank on a vehicle, an attachment point that keeps the strap attached is obviously the right choice. If you just have to pull forward and can keep tension on the strap and you have a strong enough hitch, you can use that.
@chrisbeatty7434 жыл бұрын
Last point: when dealing with force, most people know the equation Force=mass*acceleration. This equation is really only theoretical because it doesnt contain all of the information. The real equation is the impulse equation. Impulse is the amount of force applied over time which is what you will feel when pulling someone out. When you just pull on someone, you are applying force over a long period of time until you reach your maximum force. If it takes too long to reach the maximum force, you will lose traction and not move anywhere. To combat this, you increase your velocity at the time of impact and by doing so, you reduce the time by a significant number. If you reduce the impact time by too much, you will begin damaging your vehicle because nothing on a car is designed for that sort of force without taking damage to protect the occupants. To give you some random numbers as an example, let's say you are 100 kg and your acceleration is 1 m/s^2 and your impact time is .5 seconds. You are exerting 200 newton's of force. If you back up and accelerate at 2 m/s^2 and reduce your impact time to .1 seconds, you are exerting 2000 newton's of force. If you use that same principle with the weight of cars, it will show you just how dangerous recovery can be If you don't know what you are doing or have the right tools.

What you are describing was kinetic energy not potential energy and it is not the same in the two pieces of equipment. The formula for calculating kinetic energy is ½ mass times velocity squared. The velocity is going to be very close however the mass of the two objects is radically different. The amount of kinetic energy in the bow shackle is going to be significantly higher than in the soft shackle.

The ball is not in " shear" as you put it. When the ball retaining nut is at the correct torque, the flat mounting surface of the tow ball against the flat tongue surface is what creates the clamping force which creates a frictional resistance to loadings. Its a similar thing to how a flanged drive shaft loading works. The bolts holding the flanges together are NOT in shear they are in tension. This tension clamps the surfaces of the flanges to create friction and it is the friction that delivers drive from one flange to the other . If the bolts are not tight enough then yes... they are then in shear and they can/ will indeed shear. When using a ball to recover of course any rope/ strap could slip off the ball so use a restraining loop to make sure this cant happen or use some other way.. Now to the second point where a hitch is located in the hollow receiver with a loose fitting cross pin. This is indeed " double sheer" but I would wager that this will fail before the ball fails[ unless the ball is damaged etc.] Now imagine if the hitch [ square tube] was clamped between two flat bars by tightening a high tensile through bolt, Now, friction will provide all of the load bearing and the through bolt will not be in shear, and I think you will appreciate the analogy with the flange drive. So to summarize, it is the clamping force that provided the frictional resistance and the threaded element that provided the tension to create the clamping force. With regard to Ronny Dahl... he is an idiot!!

Eventually the vehicle will rust and fall apart due to gravity. Matt, your going to have to do better . Now of course, lets not forget that " road wheels have been known to fall off vehicles and kill people " and the reasons they come off are not dissimilar to the reasons why towballs may fail, The roadwheel is held in place by the clamping force [ creating friction] between the wheel mounting flange and the axle. To maintain this clamp force the wheel studs must be torqued to the correct value so that the studs are never in shear... only tension. Again it is the friction created by the clamp force that is important. So by all means make more video' pointing out that a tow ball stud mounting nut MUST be torqued to the proper value so to prevent this part ever coming into shear. When the stud is prevented from being in shear the next point to fail will be at the " waist" of the ball. Well good luck snapping the ball at the waist.

Did the towed vehicle take all of the slack before moving off slowly or did it do a " ronny dahl " charge in the false hope that this would help ?. Matt, you must do better than this.

@@tiltingvehicle1844 You are defending poor practice here. Yes we don't know the full circumstances but at the end of the day to defend the use of a tow ball as a recovery device is foolish. You must do better than that. It is so easy to use correct gear that for the most part is better than a tow ball. So stop defending poor prcatice.

What’s your thoughts on just using the snatch strap and the pin (in case you don’t have the recovery receiver)? (I do have the proper receiver hitch) but just throwing another scenario out there.

Thanks for the good vid Matt. Any thoughts on why a tow ball can tow a trailer thats 15,000 plus pounds no problem? a truck that needs to be recovered is far less than half the weight of most trailer towed. It holds all this fine and never breaks while towing. How is recovering different from daily towing especially up and down high mountain passes in Canada? Thanks
@MadMatt4WD4 жыл бұрын
Sure. The amount of traction required to move 15000 lbs is not 15000 lbs. you can push a car but you can’t lift one. Also we’re factoring for fatigue over time.

Its because he doesnt know what he is talking about. In canada with full sized trucks your towing ball should be 1 1/4. Think its rated for 30,000 pds. Your slings or chains will break long before the ball will shear. I've pulled bumpers off trucks ripped tow hooks from frames. Never broken a ball.

@@MadMatt4WD 1 of 9 in 20 years with a mention of a tow ball and I'd put money on it that it had part of the tow bar with it. If it was the ball that snapped I'd put money on it that a chain was being used. I mean seriously Mat, surely you're smarter that Dickhead Dahl and can see from his video that tow balls don't snap from use with a snatch strap. You need to do better. I'm sure you have good intentions, well I hope. But by adding to the towball scare, you're endangering more people who will opt for something of questionable strength that is more likely to fly at people, because they believe blindly that a tow ball is a straight up no go. Most of the vehicles out there the strongest thing on their car is a towball, and unless they have hundreds of hp and massive tyresm there's no way they can possibly get enough momentum to break telstra rope, let alone a towball. But if they're scared of the ball and desperately find something else to connect to, there's a good chance they'll hook to something that will fly off and kill, like a bull bar or rear bumper. Warn people to take extreme caution and to educate themselves, because as evident in the link you provided yourself, people are hooking to all sorts of things that are clearly not up to the task. One of the things that people connect to that also fly off at fatal speeds are those cute "rated" recovery points that all the big brands sell. Don't be a suck hoping the big brands might give you freebies or help promote you. Don't be scared to tell the truth about their rip off, selling priorities. They don't care about people. At least the people should be able to trust people like you to tell them the truth. Don't mislead them!!!!!

Scotty You obviously know way more than the rest of us so who am I to question your infinite wisdom. Why come here to insult me and make assumptions about what i know and do? Have a mature debate by all means, we do not have to agree thats fine with me. I'm only too happy to be wrong. But the way you're approaching this is with arrogance. Now I will respond in good faith that you will stop with the attack and begin to have a helpful conversation. You may notice I'm one of the few channels that actually responds to nearly all the comments. Thats because I'm serious about what I do and serious about helping people. Did you know it is mandated in Australian standards that you must not recover of a towball? It is one the label of every snatch strap sold. So why am I wrong to repeat that warning? At the start of the video I say towballs and hitches for very good reason. That is because the hitch is known to fail. Do you know what the Hierarchy of recovery is? I don't like the rated recovery business either and prefer to use the terms of suitable recovery point. Unfortunately everything gets attached to a thin piece of chassis in some way which is hardly a good solution but if a Kinetic recovery is done right we know that it can work. I personally hardly ever do a kinetic recovery prefering one of the many other methods available to us. Lots more I could say but it's late and I'm off to bed. Oh and I don't like swearing and calling people names on my channel so let’s try and keep some level of professionalism. I found this comment in the junk pile and approved it to have this conversation.

You're talking about weakpoints and such so I'd like to point out that the bow shackle your holding is rated for 4 3/4 tons, or 10,471 lbs. it's a cheap one too so it's likely rated at a 2:1 ratio (Their website gives absolutely no specs beyond a 10$ price and a good shackle rated 5:1 or 6:1 would be around 30 bucks) but that gives it a max limit of 20,942 lbs. Now that's fine in quite a few situations because you can expect to introduce forces to it of about 3 times the weight of whatever vehicle you're attempting to yank out of a hole. but only if it's being pulled straight, if that pressure is introduced off center than it reduces it's over all limit considerably... granted I'm just reiterating what someone else has already written on some other website. But the point here is that for someone focusing on safety I feel like you should be using higher quality tools.
