For all you engineering types. There is a offroad webpage,
http://www.landroverclub.net/Club/HTML/Winch_choice.htm
that talks a little about different winch types and at the end of the page goes into a little detail about a DIY project. Let me quote part of the article.
Go visit junkyards on a search for any winch of reasonable size up to a mechanical Braden, 5-tons, which is about the heaviest you can carry. This is the same winch found on WW II GMC and Dodge trucks. Anything else will do too but keep it cheap and it is not important whether it has a drive or not. Once you found something, the next thing you do is to fabricate a mounting for placing it on the front of your Landy if it will fit in between the wings, or somewhere in the back or under the chassis if it happens to be too wide. It does not really matter if your winch is in the front or in the back of your vehicle and I have often seen Swiss and German show-offs with two winches.
Ok. now that you got a winch, what comes next ? Get a drive for it. Best drive you can find is a NEW hydromotor in the 8-10 HP range and capable of some 1500 / 2000 revs. ( These sell from industrial outlets for around EUR 370.-- ). The pump you need is an ordinary second-hand power steering pump. Furthermore you will need an adaptor shaft for coupling the motor to the winch and a fabricated mounting for the motor, high-pressure hydraulic fluid lines, an oil reservoir and a forward/reverse valve that you can mount anywhere in the oil lines. Estimated cost: (in EUR) 80 for the second hand winch with a shot motor, 370 for the hydromotor, 100 for the lines and the valve, 50 for the servo pump and maybe 100 for the shaft, which will set you back some EUR 700.-- This is very cheap for a good hydraulic winch that will keep going long after all the others have burnt their electric motors or exhausted their batteries.
So my questions to you real and closet engineers are, “ does this make sense? Would a regular duce winch be a suitable candidate? Will it work? Are the rpm and motor size recommendations in the ballpark. “Inquiring minds want to know.
