I am helping a ham with a TX472 that has a new Raising Fixture, TRX 80HD.  It 
is attached and ready to use, lowering the nested tower for maintenance and 
antenna work.  The raising fixture has never been used and I am looking at 
the gear box wondering what keeps the tower from "taking off" when you start 
to let it down. There appears to be a clutch mechanism in the gear box that 
will prevent the tower from lowering itself at a high rate of speed.  Has 
anyone used one of these? and is the clutch mechanism the "safety" device 
during lowering, or is there something I am missing.

Thanks es 73 Bill  K3SV
