Whoa! I once tried to draw a sketch of the crankup winch, cabling, and
pulleys on a LM472. It didn't turn out very readable. I think that I learned
that the only thing keeping the tower cranked up is the tension on the winch
from the cabling.
If that is loosened to attach a replacement cable, wouldn't the tower come
crashing down?
