Brings up the "lower it a "smidge", oops, raise it a "half smidge"

I have  only used a crane to assemble Rohn 65G and it was pretty easy to
align the  bolt holes with just a large screwdriver. I would think with
Rohn 55G you  would need really good communication with the crane operator
to drop it in  place while you align the tubing. Gravity will easily push
it down to the  stop and you should be able to align the bolt holes with an
alignment punch  or screwdriver.

I do not have crane experience, but I am curious about one aspect  by those
that do.



If you have a top assembly of a few tower  sections, mast and long yagis all
being hoisted as one assembly by a crane  to top off the install, how hard 
is
it to get the legs of the section to  drop in and not bind and get the bolts
through?  It seems like the  moment arm pivot would make that highly
problematic.



Curious  by those who have done that - on the tower - and slid the  bolts
through.
