Sorry no he's still in the field
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
No, now he is stuck in the hole left by Phil's 5 ton.I stand corrected. I went back and reread that post, he did say the shaft twisted, likely due to an improper weld. Understood. So.... to clarify, was a snatch block (or 2) in use at the time? Based on how badly you mentioned it was stuck, sounds like there is no question at least 1 should have been in use..
So.. the big question, you said, "How badly stuck he was stuck", does that mean the truck is now back to sleeping at his house rather in the field?
I went out in my civy pick up a week or so ago to "look" and see how bad a friend's SUV was stuck. A couple people were telling me it was IMPOSSIBLE to get out with my deuce. We checked everything out in the pouring rain and went to get the deuce. We were having FUN. Then due to some bad advice backing up my civy truck slide off the side of the road. Fun was OVER.Wow, I wouldn't want to be that stuck in my M38 let alone a Deuce. On the other hand, it might be fun to help if it was someone else's truck.
Best of luck.
Thanks for your concern, it is appreciated. As for the physics aspect of it I have a reasonably good working knowledge of how to use blocks, tackle, levers, and ramps to gain mechanical advantage. The driveline failure was a freak thing or possibly due to the pin not meeting spec. Back in the 80's their was a major problem with counterfeit hardware from china making its way into the aerospace and defense market. Who knows if it was heat treated correctly or that they used the correct alloy. Their is a **** of a difference in strength between 7575T6 and 6061T6 .375 dia pin in double shear. The thing that has had me stumped was how to anchor to basicly goo to pull a load. 1 to 1.5 foot below the surface and you hit water. A dead anchor will work assuming I can sink enough surface area into the ground over a very wide area.You know..... not being a smart a$$ at all but...
This is the second time in less than a week that the PTO pin sheered. Notice I did not say "Failed". It did not fail. It did it's job and committed suicide to save the winch from destroying itself in an overloaded situation.
Why did the pin have to shear in the first place? Simple, operator error.
What error?
Failure to use the proper equipment and technique for the job.
What equipment? What technique?
In both cases (This one and the one earlier in the week) it was clearly the failure to use one or more snatch blocks to double, triple or more the pulling force of the winch. In both cases, there was plenty of anchoring for the winching truck, just not enough available safe winch power to do the task in a straight line pull.
Yes!I never thought of using the pulling truck and two snatch blocks. Does this method still multiply the pulling force or does it simply spread the load over more cable?
I was digging around on youtube to find some winchouts and ran across a disturbing video. No doubt you'll have a few unhealthy thoughts about this one.

Them guys must be related to jeep boy from the GA rally!I never thought of using the pulling truck and two snatch blocks. Does this method still multiply the pulling force or does it simply spread the load over more cable?

The only benefit of a doubt on this one is that maybe they didn't realize how catastrophically dangerous their position was until they saw it from a different angle.I was digging around on youtube to find some winchouts and ran across a disturbing video.
