[RE-wrenches] tower lifting winches

[Dan Fink]

Hi Nik -- We shop around locally and on Ebay for slow, large-ratio 
worm-drive winch bodies that are power in/power out. We give them a 
safety check, lube them up, and then they are usually mounted 
permanently near the customer's tower. We usually then power the winch 
with a cordless drill and a couple battery packs. The limit on that 
depends on the gear ratio of the winch, but it's been fine for 60-80ft 
towers made of 6 inch steel tubing. If the tower is larger or higher, or 
if your cordless is wimpy, look for an AC gear motor to power the winch.
