Here's a question for the ME's.  Can a worm gear drive winch without a brake 
system safely be used on a telescoping tower - which tower does not have a 
latching mechanism to support the tower in the extended position?

In other words, can a worm gear drive winch be reverse driven such that the 
tower can fall in the absence of a braking mechanism?

I have a TriEx W-51 tower that came from the factory equipped with a worm gear 
drive winch.  When I received the tower, the winch handle was missing.  If I do 
not replace the handle, I can likely drive the tower up and down using a 1/2" 
low speed rt angle electric drill.  If, however, the handle needs to be there 
and if said handle needs to be locked in place to prevent self-unspooling of 
the cable, then I had best find a handle...
