Oops!
I now see that the question about the Tailtwister not fitting was the TX
model. Don't know if the top section is different dimensions than that
of the HDX model.

This thread just refers to a UST 72 crank up. Specifically, what
model will not accept the Tailtwister? I have the HDX 572 and the
Tailtwister fits fine.
I am now using the Orion 2800.

To be more specific . . . my former Ham IV motors (too weak for my 4
EL Stepir) and my current Yaesu G-2800 both fit the TX-472 rotor
mounting area w/o interference in crank-up/down. However, for
example, a Hy Gain Tail Twister will not fit and allow full
crankup/down of the tower. So, what rotator are you using? - Alan K9MBQ

Sounds like something is jammed and preventing the tower from
extending . . . so block the sections and suggest climb up an look.
Verify that the rotor cable and/or rotor body is not protruding such
that it fouls the next tower section, and also check the cut-out
switches to be sure they are clear.

Subject: [TowerTalk] US Tower 72 ft crank up grinds to a standstill
Hey guys,
I have a US Tower 72 ft crank up. I just put a Steppir DB36 with
NN4ZZ's
Tilt Plate on it. I cranked it up to vertical & turned on the motor
to raise
it to 72 ft. The motor turns a few times with the tower not moving
up & then
grinds to a stop. I haven't climbed up to see if I left anything
stuck in
the tower to keep it from moving. I feel like the problem of that
is pretty
slim.
Let me add a few more details that my give a hint to the more
knowledgeable.
The tower has been tilted over on its side for abt a year. A couple
weeks
ago, after I had the Tilt Plate & Steppir connected, I discovered I
had put
the rotor (located inside the tower) on, turned so the cable
connection wud
not clear the tower when it telescoped up. I had to run the tower
out abt 6
ft with the Steppir on it so I cud get to the rotor & turn in.
Any thoughts, suggestions wud be most appreciated.
73,
Fritz K4OAQ
