I had a Crank up tower(54 ft) for a while and I did not trust the thing for
climbing. I put the blocks in that you guys are talking about but just the
smallest slip can be disastrous to your fingers and hands. So I decided that I
would crank the tower down and then rent scaffolding up the side. I felt much
safer and I had a nice platform to work with. If the tower slipped then I was
not in harm's way unless it fell all the way down.

Thanks for your response.
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
