I have the same tower.
I block it with the largest wooden pieces I can jam through so there is
as little play as possible.
You must make sure every section is blocked and can't move.
Then I lower it until the wood is slightly compressed and the tower
can't move at all.

Me again,
How do you guys with the motorized towers block your towers ? I am thinking of
using 1 inch water pipe.
And where do you block it ? Since it telescopes, do you you put blocking
through every section ?

Following this thread made me realize I will now block my motorized tower
before climbing.
I have a US Tower HDX-589MDPL and I have been lowering it down till it stops
then climbing.
But as pointed out, it is supported by the lift cable even when all the way
retracted.
Thanks for the info guys !

In my situation I have no zoning concerns, no inspections, no home owners association, or
such. I am subject to FAA concerns if the tower is tall enough (red and white alternating
paint and lights.) I do have neighbors but the nearest are 1/4 mile away and not in the
“kill zone” of anything I would put up. I have a small black Angus cattle ranch
(cow-calf operation) on 160 acres so I can get pretty wild with sky wire and such if I want.

Patrick,
Yes and yes. I installed a 3-section 72 foot tower (US Tower TX472)
last July with the optional tiltover fixture. The tower manufacturer
clearly states that thou shalt not climb ye olde tower. In fact, with
motorized drive, I can have the tower up/down a lot faster than
I can climb it. Having it down and tilted over also means not having
to be concerned that I have all the parts and tools before climbing it.
My concern is the condition of your tower (mine came to me in perfect
shape) and the modifications to it. If you are required to have a permit,
your zoning and permitting agency may require wet-stamped plans for
your particular installation, from a Professional Structural Engineer who
is licensed in your state. My county building department required it for
any tower structure over 35 feet tall that is not part of an existing structure.
I hired Hank, KR7X and he supplied me with everything I needed. I
suggest you look into the permitting requirements BEFORE investing
a lot of time/effort/money into your tower.
vy 73,

Wouldn't you ordinarily lower a crank-up tower before climbing? If it were a
tilt over as well wouldn't you tilt it over instead of climbing it?

Well, if the tower should telescope while you are on it, the shearing off of
fingers and the front of your feet might be considered an undesirable
possibility.
If you are on an upper section when the collapse occurs, you might get by
with just some foot damage and being thrown to the ground as the section you
are on drops into the next one down...
Your plan is much like the old EZWay towers. There's a book for the two
section 40 footer on BAMA. http://bama.edebris.com/manuals/ezway/rbs40
