[TowerTalk] Lifting 45G?

[Pete Smith]

Surely there is a rigger's trick for doing the initial pick as you describe 
and then transferring the lifting point to the top of the stick as it 
approaches vertical

At K4JA, he had a crane put up 2 X 100 feet of super heavy duty AB-105 for 
a 40M stack.  The crane had no clearance above the top of the second piece, 
so the connection had to be just below the top,  and because it was not 
vertical, the climbers had a very hard time getting the bolts in at the 
joint. It would be worth trying to find a way.
