Ken,
Crankups are notorious (or at least used to be) for settling to their own
weight when cranked down, then settling just a little more with added weight
of someone climbing on them. Tends to chop off fingers! A ham friend once
described to be how he carefully inserted well-cured 2x4's between each gap
through the tower as he climbed, to protect his fingers from crushing.
Sounded too scary to me. I'm happy to tilt over my crank-up. Besides, when
fully nested, the antenna is around 23 feet off the ground, so I'd need to
either climb the bracing or use a ladder, neither of which appeal to me. I
used to climb my 120' Doug fir tree here where I mounted a Rohn 25 tower top
to install my cubical quad and rotor. But I was 30 years younger then, and
just a bit more cautious now. Maybe newer crankup designs have built-in
stops or brakes for safety. In that case you should be fine.
73,
Steve

Why would you never climb a crank-up when nested? I'm considering putting
up a tower, and your comment made me curious.
Thanks,
Ken
