Bob,
I have a 72 foot tri-ex tower . Have never user the motor control for it.
I have cranked it up and down manually many times. You are correct it takes
a lot of cranking. Once I counted the turns. It took about 1000 revs to
lower each section ( also 1000/sect. back up UGHHH).
Good luck,
73 Joe K2UF

Subject: [TowerTalk] Manually crank down a motorized tower
I have a US Tower HDX589MDPL with the motorized drum. I was wondering what
I would do in the event that something failed in the control box and I
needed to crank it down.
The gearbox has a worm gear and I believe I could temporarily take off the
chain and turn the gear box sprocket by hand. I would have to turn it until
the cows come home but I think I could crank it down. Am I correct about
this ? Have any of you had to crank down your motorized tower by hand ?
