I've finished building a 21'x36' wood framed room within my shop. I've designed the ceiling joists and beams to have a flush top and accept a 40 lb/sq. ft. loading for storage. Not wanting to carry things up a ladder, nor wanting a stairway, I was thinking about some sort of hoist/elevator setup. I own two H.F. 880 lb. capacity electric hoists (often on sale for $74, and they worked wonderfully for unloading things from the back of the moving vans to the shop floor). Preferably, I would like to hoist up a loading platform upon which I could also stand and get a free ride. Now, if I simply use a single cable, the platform is going to rotate and sway. Is there a way to rig cable so I can lift by all four corners and therefore eliminate the sway etc. I was thinking something along the way the old drafting table parallels were wired. I suppose a four post car lift is also wired (cabled) off of one power source with the cables running all over the place.
Any ideas? Should I simply build a vertical shaft and use rollers against the sides? Some of you must have already solved this or have some thinking that goes beyond my imagination.
All thoughts welcome and appreciated.
