searching the web, the guys putting up wind turbines have done
some seriously big tiltups. They tiltup 100' 6" tubular poles with a wind
turbine on
top. (with a lot of care and detail to how to do it)
they fix the gin pole at right angles to the tower, and use a lot of
guys/lifting
wires.

or with almost nothing on top (wind monitoring for instance)
