Guys-
I'm confused...I see this thread about Fulton winches, which is type I have
on my US Tower HDX-589 to tilt over the tower. But then I see comments
about winches that will be used to raise the tower. Are you all talking
about tilt-over winches or winches to raise and lower an already vertical
crank-up tower?

Subject: Re: [TowerTalk] Anyone using the Fulton KW3000 worm drive?
I replaced a K2550 with a W3000. When cranking up, there is a considerable
increase in effort due to the friction of the worm drive. The additional
2:1 gear reduction of the W3000 approximately cancels this out. Cranking
down is probably less effort than the K2550, since there is no break to fool
with. I found it necessary to heavily lubricate the winch, smothering the
moving parts in grease. Unfortunately, it is difficult to get the grease to
really penetrate. The last time I used the W3000, it started squeeking on
the way up. This is apparently due to the worm bushing spinning. The winch
gets fairly hot in use; I don't think it is designed for the kind of duty
cycle involved with raising a tower. I plan on replacing it with a boat
lift winch (see:
http://www.w4abc.com/drive.html). These winches make the W3000 look like a
toy. In your case, the W3000 may be oversize for your tower (since it came
with a K1550) and it may work out for you better than it has for me.
