I do question the value of having passengers with the danger zone of any recovery like that.....

The pin is rated to the bar. It will however bend with only a strap attached. I just had some tested for a project as follows.
I have made some sample 4140 receiver hitches for 6.5T 1"pin shackles and 4140 pins to go with them. Having the parts destruction tested as an assy and individually but had the std pins tested already. As part of the bar where it's loaded at a smaller area (just around the holes) it passed 4T without deformation or any visible damage or NDT test damage.
The receiver hitched I made are solid and only drilled for pin and shackle and have only 6/5mm off each side to allow the shackle to pass over. Initial test of the pin material as a bare length 250mm long, with a shackle in the center and one each side to pull elastic deformation (given 400,000psi tensile strength) was over 8T and plastic deformation over 10T.
Next is destruction test of same material and method then assy testing for both elastic, plastic and destruction.
I know you can buy them and they average $40- or so but I can make for less incl test cert and much stronger.
I wholeheartedly agree with you.
Maybe instead of calling it an accident, I should have said "death and destruction"......
I find it utterly ridiculous that people still play with their and other people's lives by taking a shortcut and just looping the snatch over the towball instead of spending a few minutes to secure it properly - those few minutes saved will haunt them for the rest of their lives!
Hi Clubagreenie
Sorry I haven't looked yet, but do you have a add in the market section for these yet? as I am interested in buying a couple.
I already have two new shackles, and did intended to make a couple of hitches for my self (no! I meant for the vehicles) .
As you have already made some, why should I reinvent the wheel?
My recovery hitch was stolen a month ago, when I was sitting in the drivers seat of my wife's discovery! Having a sleep while waiting for her to come out of the shopping centre, I was in the advanced stages of the flu and feeling pretty crook as well. I woke, thinking I heard a rattle noise at the back of the car, had a look in the mirrors saw nothing and dismissed it. Unpacking the next morning I noticed it gone! b****r, I now wish I had taken it off after the weekends trip!
I hope that whoever took my recovery hitch, now uses it on his vehicle and puts the end of the snatch strap on a weak tow ball to test its strength, and nobody else gets hurt whilst sporting a new bit of character on his moron mobile!![]()
The thing I am tempted to do now, is to weld a link on the inside end of the hitch, connecting that to a device that squirts ink when pulled.
Cheers Arthur
