[TowerTalk] ALM-31 Tower question

[Bob Richards]

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.

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.
