That 2500 lbs isn't torque. It is line pull without multiple layers of
cable on the drum.

Hi,
Just want to share my experience with a " cheap" 2500lb Electric Winch.
Tried to use one ( actually even tried a second one) to lift a Hazer type
device up 40 feet of 45G. My load was about 300 lbs total. What I found,
is that before I had a chance to even try to lock the Hazer device in
place, the winch would begin to creep down, once I took my finger off the
up button. A winch is not designed to lift.
Also, 2500lb of torque is a powerful beast and I learned that if
something goes wrong, in a split second that 2500lbs of torque can rip
apart cables and aluminum, before you even realize there is a problem,
because there is no feedback. I learned that the hard way.
Based on the advice of John, W2GD, Antenna and Tower Installer
extraordinaire, I switched to a Fulton K1550 manual winch and had a local
welder make a custom mount for the tower. I have complete control and can
stop it on a dime. My recommend is to go with a Fulton Manual Winch.
By the way, to power my electric winch, I used a Sear car 12V battery
boosters (500 peak amps/400 cranking amp) , just left it trickle charging
until I wanted to raise or lower the antenna.
