I just (last December) bought a 12V winch on ebay that has 1500 lbs dead
weight capacity and is fully reversible.|
It has a 1/2 HP motor and will pull 500 lbs at 12 ft/mn (35A current at that load) when the cable is on the first layer.
I use it with my folding tower. The only problem was that it came with 30' of cable, where I needed about 36'. I was able to transfer the cable from my old manual winch to this one. It is a little larger, but still fits nicely on the spool. In my case, the maximum load occurs when the cable is completely out to 1/2 reeled in. When the spool is almost full, the load goes down to zero.
Beside a kind of grinding noise when it runs, it seems to be doing fine. Time will tell.
I paid $65 plus shipping for the winch. I power it from a 12V AGM battery located inside the house, with about 50' of #8 wires. There is appreciable power loss through the wires, but acceptable for my purpose.
By the way, the winch IS made in China (how did you know? :-)

As a practical matter, 12V winches are going to be pretty expensive and inefficient compared to a 110V, except for possibilities of economies of scale. (i.e. if you are making zillions of them in China, compared to just a few in the US). Wiring is a big issue...
