I thought my first post defined some of my ideas. I'm thinking that a 8000 pound electric winch (like the one on my 4X4) would provide plenty of lifting power. They have built in brake systems for no slip response. It need to lift to a third floor, say, twenty feet. Possibly use a double cable system on the drum (for safety in case one cable shoud break, which I doubt with a 1/2 inch braided cable. Hoist could fit in the attic. Some kind of stop switch mechanism to stop at the top and bottom floor. Dave, I'm gonna keep you in mind when I get a little farther along with my ideas.
