McMaster-Carr sells hand winches with auto brakes so they will not free wheel.
Might be a solution.

There's still another side to the power winch and safety. A neighbor has a
crank up tower that got away from him,
using the factory crank, and a broken hand was the result. A power winch
would have eliminated this safety issue.
Murphy's law also comes into play with the hand crank...
There've been others in the group that have advocated using the power winch.
It depends on the design of the tower and
the winch, whether it will handle the torque and how you design the
installation for safety.
