    So you've been working on the tug's too ! Don't they use that synthetic rope now? I remember watching "How it's Made" and all the tugs seemed to be using that Purple synthetic rope.

    The 230 foot fuel barge had a rope hawser and the Tug had steel cable. I was offshore towing late 1970's Louisiana. Its was funny first day on the job and I figured that when we let out maybe 400 feet of the cable it would pull tight and we would be towing. No the line has a big belly and almost seems like the tug pulls the belly and the belly pulls the barge. Ruff water you wanted a big belly in the cable. Good job, good food, great people.

    And a circuit breaker between the winch and batteries. I use my winch on my dodge cummins pulling firewood in the woods a lot. Im buying a Deuce now to replace the dodge and will add a 18-24K winch. I have snatch blocks, shackles and pull cables with extra crosby cable clamps. Remember to gets some good (from a rigging supply, not HF, in this case) 20k "basket" rated eyed straps to wrap around trees and set your block for either doubling up your pulling power, or angle pulling to keep you from going someplace you don't want to be.

    The Sherpa Stallion has synthetic rope option. 1100$ is a very good price.

    Yeah I think I'm definitely going electric winch and then hoping to never get stuck!

    when I was young (decades ago) you could pick up old WW2/Korean war landing panels real cheap. they were approx 2'x8', 14 guage steel with 1 1/2" holes punched through them with a little 1/8th inch lip to grip the soil. Id like to find about 4 of them for traction mats when I do something stupid. I bet they cost a bundle now if you could actually find some. Seabees would know what they were called.

    he snatch block is your friend. The issue for a WW truck is one but I would carry more if I was going someplace where I expected to get stuck. A block can do 3 things but one at a time: develop mechanical advantage, change the direction of the pull or serve as a trolley block. The ratio of sheave size to the cable is 12:1. 1.5" cable = 6" block. If the sheave is appropriate for the cable then the hook and sideplates should match too.

    Is that a M60 or M48 tank ? Looks like a M48 but it has been a while since I last saw one .
    I like the way they used the snatch blocks here. Basically it is a "Quad" pull (doubled and then doubled again) with a third less line used. When I went through Tank school they taught us all kinds of rigging technics to basically "unstick" a Tank.
    I still find it quite fascinating how a single line from a single winch can be configured to pull such tremendous loads by just using a few snatch blocks and anchor points.
    Those ancient Greeks where pretty smart ! At least I think it was the ancient Greeks. Maybe they stole the idea from some other ancient race that got wiped out. At any rate it was some ancient man who came up with the original idea.
