[TowerTalk] TowerTalk Digest, Vol 91, Issue 38

[Dale M. Schwartz]

I use an inexpensive winch to TILT OVER my US Tower 55' flagpole. The tower weighs about 800 pounds and the winch works great. They warn that it was not designed for anything but pulling a boat on to a trailer, but it is rated at 1500 pounds.  I'm sure the engineers will tell you reasons why you shouldn't use this winch to LIFT heavy loads, but I can tell you it works just fine.  In fact the one US Tower provided with the $8,000 tower failed and we had to replace it.  I'm sure I would not want to use it to lift this tower up and down, as the big electric motor does that smoothly, but for lighter duty they work just fine.

Heh - How RF rich are some of these sites?  I saw one where the guy had a 2m band antenna, and he hooked up his bird watt meter to the antenna (and NOTHING else - no rig etc) - he was reading 5 WATTS inbound on the antenna - Not uV - not uWatts - WATTS

I would like to know too as I bought the Harbor Freight several years ago
and have just never gotten around to installing it as high up on house and
as close to the nested height (25 ft) of a 50 foot small footprint aluma
tower with an A3S, 15 element 215WB 2 meter boomer, and Yaesu G800DX rotor
on the very top of the tower (inside section of tower not large enough to
allow mounting in tower.  I do not have the specs in front of me, but I
recall it was rated quite adequately for weight it was able to pull, and had
a brake that would not allow it to free wheel down when lowering the tower,
although there is a free wheel lever than can be activated, I was
considering safety affixing it off so it could not be engaged except in a
very deliberate attempt.  It is the model T1500 now that I went and looked.
Max lbs. 1,500; speed ft/min max 5.2; min 1.6 ft/min; current draw 12VDC
0.67 hp 90 amps at 1,500 lbs; 60 amps @ 1,000 lbs, 30 amps at 500 lbs, 20
amps at 250 lbs.  Must be mounted in the under wind position.  It has a
winch control cable that hangs from the winch with a rocker switch.

Any thoughts on using a Harbor Freight winch for a U.S. Tower 55 ft
crankup??

I think the one sold by U.S. Towe is around $1200 versus $150 for the Harbor
Freight model.

Is there a duty cycle spec?  Consider that 12V at 90A = 1.08 kW.
At 0.67 hp, that's 50% efficiency.  Gonna heat up in a hurry.
