Recovery Gone Wrong

Wow, gone wrong indeed. Still doesn't make sense to me. Is the tug producing that much more force?

Tugging/jerking always applies more force.

Myra run, I had a fear of this.. I threw the jeep one end of the tow rope, I was hooking up mine using my shackle, I didnt noticed till in the truck that was just a hitch pin holding the rope.

Wow, I would not have thought it would break that easily either! But as James says, it is where the force is applied. Normally the strain on a hitch pin is right against both sides/ends on the inside of the receiver, creating a force trying to shear the pin on both sides. And they're really designed for relatively steady loads, not jerking loads.

If the strap happened to pull right in the centre of the pin, it creates a 'bending moment', which is a different force altogether.

Anyway you look at it, it is testament to using the right equipment for the job, and standing clear! I've often wondered about the difference when using a tow strap as a recovery strap, a tow strap isn't designed for shock loads either. And maybe there are different grades of hitch pins, Grade II, Grade III etc?

LOL. I just read the Jan Club Run thread and it was said much easier there:

""Because you're putting stress in the center of the pin, where the draw bar distrubtes the weight across.""

Its very true, since wheeling with this club I have learned a lot about recoveries, mainly cause ive been the one being recovered lol, but in all seriousness there is a lot I didnt know that I am glad to know now!

Is that synthetic winch rope? The elasticity is the difference between a recovery strap and a tow strap.

no its not like the stuff used on winches... i do keep a piece of that with me too but its like 3/4 or 7/8th bigger then the winch stuff thats like using wire its just as strong wire but it comes snug like wire..... hard on the gear lol

the 7/9ths nylon samson braid will strech like crazy i pulled a 3/4ton 4door long box chev out of soft spot at work once... rear end was sunk to bumpers front was not as bad.... i was in 3rd gear when she come snug out comes the heavy chev.
