Re: Rigging a chain, a cable, a tow strap, winches, and more...
1. I think the pin would go in the loop, and the moving part would go through the U of the clevis...you'd want the nice flat area to hook to, right???
2. Ok, so let's say farmjeep gets really buried, and I want to pull it out. What sort of "equalizing" chain do I need? The clevises are about 3' apart...so make a 5' chain with a hook on each end to grab the clevises and then what? How would I hook onto that chain? What is the equalizing roller you mentioned? How does it get rigged? If I'm only pulling a short distance, then hooking through one clevis, to the pulling vehicle, and then back to the other clevis (in a big U) works great...but what if I don't want to get anything quite that close to me and I don't have enough chain for a double run? How do I make the little U with the short chain at the clevises equalize the stress?
3. When the elastic section of the rigging (be it rope or yank strap) stretches, it stores energy. When it contracts, it releases that energy...as I understood it, the contraction and resulting release of energy makes a lot of force because the contracting happens quickly, compared to the stretching happening slowly. So would the peak force of a elastic section contracting be more than the peak force of a solid link? Or does the elasticity work differently than I understand it?
4. How do you turn with your cable rigging running under the dozers? If the turn wasn't entirely coordinated, you would run over cable, wouldn't you? And when you turn, if the cable is running under the middle dozer to the front dozer, aren't you putting a lot of torsional (side) stress on that middle feller?
5. Any ideas on how to transmit that stress through something other than the frame? Maybe run a cable alongside the frame on both sides and then bolt it to the rear bumper??? Or just have two loops hanging out under the rear bumper to hook to? Or something else???
6. We've never used cables for anything here in the farm...Perhaps you could provide a tutorial on the proper selection of cables...as I understand it there are a number of different types of cables (just as there are different grades of chain)...What should a fellow use?
