Hi Steve,
I'm not familiar with your model of crank up tower, but I have a
Tashjian WT-51. I replaced the factory winches with Dutton-Lainson worm
drive winches with hex drives. The winches come with a detachable crank
handle that uses a 5/8 inch socket. Instead of the crank handle I use a
heavy duty electric hand drill with a 1/2 drive 5/8 inch socket. The
other advantage to this winch is the worm drive design that under
tension holds the tower at whatever level I stop cranking. No brake or
ratchet assembly required.

Hi everyone,
I own an ALM-31 tower that I've got permanently mounted in my back yard on the US
Tower rotator base assembly. The Stepp-IR Urban beam and 2/70 yagis I have on
top puts me right at the 50-lb maximum loading recommended by US Tower when it is at
full height so whenever we get wind forecasts of 25+ MPH, I lower the array just to
be on the safe side.
Now, after two plus years of flawless use, I've become annoyed with the need to
raise and lower it by hand and was wondering whether anyone has figured out a
way to add an electric motor and gear box to the winch to replace the cranking
handle.
Thanx in advance for the help.
73,
