I have a punching bag that normally hangs vertically, but I want to lift it up out of the way when not in use. The bottom of the bag has a strap that I can attach a rope to, and I have set an eye-hook off to the side so I can lift the bottom up to be level with the top so the bag is horizontal and overhead.
The bag is pretty heavy so I need some type way to easily pull on the rope to lift it and not have it fall back, yet also be able to easily lower it when needed. Because it's quite a bit over my head and is about 200 lb (90 kg), it's pretty difficult to try and push it up while also trying to rig something with a knot(it might be easier with a ladder but I don't want to have to haul one in every time I want to lower it or not nor do I want a pulley system with a bunch of extra stuff). Clearly it should not slip since I might be walking under it some times. (just in case).
