You have it right. The weight of the tower section causes it to come down
when you crank it down. However, if the wind is blowing hard, the weight may
not overcome the sliding friction and you might get sticking and slack cable
with sudden release. Some towers have a cable attached to the bottom of the
top section and this is reeled into the winch drum for power pull down. I
have a cable attached to the bottom of the top section hanging free down the
inside of the tower to the ground. If the tower sticks I run the cable over
a floor pulley chained to the base and can pull on it with my tractor or a
car to help free it. This has happened only once to me in 12 years. A little
hammer work on the angle guides to loosen them cured the problem. Good luck
with your tower.

Hello All,
I just completed putting the rotator on the tower.
The tower is in a horizontal position and I cranked the inner tower out
approx 4ft for easy access to install the rotator per the instructions.
When I go to crank (retract) the 4ft all I get is loose cable off the crank
reel. I can push the 4ft back into the tower just fine
and it tightens up the loose cable.
( Tower cranks out(up) just fine).
My question is if I crank the tower all the way up(with antenna mounted)
once I get it into the vertical position and I go to crank
it back down am I going to get loose cable and the tower starts to
"freefall" back down?
The instructions indicate you should be able to retract (the 4ft) tower
without cranking it to 55ft first then crank backdown.
But it appears that comment is if the tower was already in the vertical
position and you mounted the rotator with it in the vertical position.
Nothing in the instructions on trouble shooting to much.
Is it a gravity thing when you start cranking(retracting) the tower to it's
nested position.
US Tower is closed today.
I would appreciate it if you could reply direct also. For some reason I
don't get all the list posted messages on the various list servers.
Thanks
Charles
