I need to transport many hundreds of hefty buckets to the top of a boom lift platform from ground level. A Harbor Freight wall outlet winch hauls at a glacial pace, which is far too slow. Any other type of winch I've seen needs a 12v connection, and even if I knew how to get that to work at the height of a boom lift's reach, I haven't found one yet that isn't also slow (~25f/m at most).
I'm contemplating a hand-operated pulley, but I'm still figuring a design that will work without burning out any human operators. I am open to new ideas.
