Take a look at www.ky6la.com
We did this for the raising fixture.. but it also works for the tower..
We used a Socket and 1/2 Power drill to power the Hand winch...
It helps to get someone to weld the Winch Nut to the shaft.
Bought a Socket at Sears that fit the Winch Nut. $8
Cut a Socket Extension Shaft ($5) and ground it to fit a 1/2" Drill Chuck
Borrowed a 1/2" variable speed reversible drill .. low RPM mode (350 RPM)
Works great

Subject: [TowerTalk] motorizing the hand winch on a US Tower MARB550
I am thinking about motorizing the hand winch on this tower. In other words,
just putting a belt or chain drive. Seems like this ought to be a lot
cheaper than putting a motorwinch on it. The hand winch has a good friction
brake that prevents runaway.
Thoughts?
I have to decide on the drive ratio details, how fast would you drive it?
