It sounds like a clutch friction type winch with one
of two problems:
1. If there is no tension on the cable, the clutch
will not work, and the handle will unscrew.
2. The clutch plates may be corroded, and stuck together.
In that case, you will have to find a way to secure
the lifting cable, while you disassemble the winch,
whack the plates apart with a hammer, clean it all up
(without using oil or any other lubricant on the plates)
Somewhere in my pile of manuals I have an exploded
diagram of such a winch. I can scan it to .pdf and
send it to you if you want. Even if it's not the
same mfr, it will give you an idea of how they go
