The one part I can't seem to find is a hand crank for the ropes
with a safety ratchet so the hoist can't accidentally fall to the floor.

I've been looking for the same for a couple of years now - I rigged the

lift it easily. All the one's I've seen are quite expensive; if you find
something affordable, post here so we'll all know.
