[TowerTalk] multi-sheave pulley

[K9MA]

I would want a fail-safe to cut the power, in case that Northern Tool 
switch shorts out.

When I first heard that W0AIH was riding a winch up towers, I almost had 
nightmares about what would happen if the winch wouldn't stop. Alas, 
that wasn't the cause of Paul's demise.

73,
