Thank you very much for sharing your wisdom on this stuff and the data regarding your testing.
You make a very strong point abbout removing as many as possible heavy metalic objects, which could have incredibly huge potential energies when line tension is high. You seem to have swayed me in this direction. For whatever reason, the slightly better bend radius of your solution just feels better than putting the soft shackly directly on the pin as I've seem some advocating for.
There is a lot to think about with this stuff it seems.
When I enterred this thread I was wondering about biggest baddest metal that will never break. Maybbe the better approach is limiting negative side effects when it does happen. Hmmm
.....If the hitch pin is the limiting factor, it makes me wonder about: why not use 2...ie a redundant pin in parallel. Maybe that really would be overkill for most people and probably only makes sense in a couple products on the market such as this Buldog reciever shank.
Good to hear. I'm not saying you have to use my device, but the device you posted is a pretty poor example of the wrong direction to go in my opinion.
My SSRA device provides a LOT of other bonuses over going directly to the pin. The hitch pins are designed to be supported in double shear. If you just put something around the middle of them, they can and will bend. If you are lucky they only bend and get stuck. If you are unlucky, the bending can pull in the short side and cause a catastrophic release. So yes, the increased bend radius is one bonus, but the proper pin support is also very important. The soft shackle is also directly loading the pin and does not require an additional connection point to worry about. The mouth of the SSRA is also radiused in every direction so that the sharp edge of the receiver hitch isn't cutting into your soft shackle reducing its life or strength. You an also change direction up to 90 degree in any direction without having to worry about loading the device wrong of creating weird side loads. While I never suggest leaving the device in the hitch full time ( take care of your gear and your gear will take care of you! ), none of the aluminum bits are exposed to repetitive damage on the trail.
I could make a strong argument that the industry should be looking at making a 'fuse' somewhere vs just making everything bigger and stronger all the time.
The double hitch pin might solve one issue, but honestly, I doubt anyone could actually break a decent quality 5/8" pin with any commercially available hitch assembly on a vehicle. I have seen hitch devices fail because the pin was not properly seated....or something like a cheap bolt was used to replace the pin. 30-60k lbs is a ridiculously large amount of force and we shouldn't be anywhere near that doing recovery work. That much force has the potential to do all kinds of damage to other things on the vehicle. When in doubt, use more shovel!
