[TowerTalk] Crane release from tower?

[Richard Thorne]

I put up an 80' tower recently and used a crane.  After we secured the 
guys the rigger went up the tower and detached the lift strap. We had 
the tower up, and antennas installed (C31XR and D240) in just over 4 
hours.  Some of the best $$'s I've spent in the hobby.  I ought to sell 
my gin pole because the 2nd tower will be put up by a crane as well.

How does the crane normally release from the section to which it's attached? That point will now be 50 feet high and I know taller towers are raised this way.
