This is a job for professionals. The sections probably weigh 300-400+
pounds each. You need all the necessary tools and experience to do it safely.
By your questions, I would surmise that you lack both. This is a moderately
BIG job.

There are dozens of tower manufacturers.
Worth? To who?
Do not add 45G or 55G sections without employing a Professional Engineer
to do the calcs and design the tower interface. No "hip-pocket" engneering
allowed.

Windlass? Cable winch? Again, please leave this to the pros.
