You can use the small ATV winches from Warn.
Brawn also make a small one that works on the Firetruck.
Might even be able to use a boat trailer winch.
A pulley is probably a good idea to use as well, especially on the smaller winches. It is relatively easy to break a single steel cable. Not sure on plasma (yet).
If you are really keen I know someone that is cutting down Warn 9000 and 9500's to make them similar to the little specialist Warn rockcrawling winches.
Very cool
cheers
