[TowerTalk] questions on the use of a man-bucket and guy tensioning

[john at kk9a.com]

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.
