I am not a mechanical engineer, wouldn't the pull on the cable be
significantly more than the weight of the tower when tilting it? Then you
plan on running a 55 amp motor with a 20 amp power supply?

I picked up a 2500 lb. rated 12V. winch from Harbor Freight intending to
use it
for tilting my HG-70HD tower. Weight with antennae and rotor etc. is between
1200 and 1300 lbs. I was hoping to run it from a 20A power supply.
I plan on a pulley arrangement that will give me a 2:1 advantage. I could
go to
3:1.
If I read the specs right, the winch draws 55 amps when the load is 1000 lbs.
The duty cycle is 45 seconds on, 14 MINUTES off. Mounting is 2 bolts,
M8-1.25x35 mm.
Seems a tad sketchy. Your opinion?
73, Mike NF4L
