I wouldn't do anything to stress that hinge, nor would I want one that 
had been "dumped over".
Dropping one even 30 feet can put a lot of stress on it that may not 
even show.

Generally you can rent a bucket truck for far less than the value of 
that hinge even if you have to pay for being trained or hire someone to 
operate it.
Working off the back of the truck (not the side) it should easily handle 
the weight of the what you have, particularly after removing the antenna 
and top two sections.

Another approach might be to put up a guyed raising fixture and use it 
either as a straight raising fixture as I do my 40 footer with AV640 , 
or as a falling derrick.
With just the raising fixture and 2:1 mechanical advantage I can raise 
and lower the 40 footer by myself.

I say this as I'd hate to see that hinge ruined. OTOH never compromise 
safety to save equipment no mater how valuable.

It only starts at 45 degrees <:-)) and grows from there.

At my age (68) I can still lift 3 sections of 25G by my self.
