Would a Fulton KW3000 worm drive winch turned by an
electric drill work for you? See:
http://www.n6rk.com/drill_adapter_for_winch/drill_adapter_for_winch.html
The KW3000 holds 50 feet of 5/16" cable. It will have no trouble with
70 feet of your small cable.
Also, consider mounting a pulley at the base of the tower and running
the cable out to the winch mounted outside the tower on the ground.
It doesn't have to be inside the tower like GM does it.
