The tower will have its mass concentrated at the 20' level, and the 50
lbs 'at the top' will have its mass concentrated at the 40'+ level.
if the 'hinge' is at ground level and your winch is at the 10' level,
the total force of those two loads will be:
2x the tower load PLUS
4x the 'top' load.
that's quite a bit for the position of the winch .. AND .. if the
winch is connected to the garage, it just might pull the garage wall
down.

Quoting Dave Tipton <dave@w5dmt.com>:
I have a 40 foot Rohn 25, with a tilt base section. It will be
sitting next to a detached framed (not block) garage with siding.
I can attach a winch to an extra guy bracket I have at the ten foot level.
There will be roughly 50 lbs at the top of the tower. (Rotator, Hex
Beam, GP3)
How much is the maximum force required to raise this from a cable at
the 10 foot level?
Thanks,
Dave, W5DMT
