IMO, and I know its not what you are asking, but I'd crank it back vertical and
with the tower extened that small amount for rotor access, use a mast winch to
lift it off the rotor and a scissors jack or bucket truck along side (Not
recommending climbing it) for the human access.
Good luck with it.

Tower current tilted over at about 30 deg via the layover fixture. Mast has a
TH7DXX and A3WS on it restricting the ability to lower the tower any further.
Need to pull the mast up enough to do a swap out of the rotator (which is
simple). Want if possible to avoid dismounting the beams from the mast. Those
with this tower know that there is only a short (very short) mast piece between
the rotator shelf, the first bearing and mast tube. and the upper bearing. I’ve
envisioned what I think I need to do but was wondering if some simple method
exists that I’ve overlooked.
Any ‘been there done that’s’ out there who have done the latter in the
tilt-over position?
