Hi Brad,
That's the beauty of worm drive winches...they don't require a brake!
I have an electric winch on mine, and I drilled a hole through the drum and
into the case so I can pin it with a bolt to take the load off the winch's
brake mechanism and provide a degree of failsafe to the system. When I
slide the bolt in, I reverse the winch so the weight is on the bolt, no the
winch's brake.

Subject: [TowerTalk] Regarding Worm Gear Drive Winches
> 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?

the tower can fall in the absence of a braking mechanism?

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...
