I’ve always seen them on TV, and in professional garages and factories. I know they allow you to lift things far heavier than you normally could. But, how do they actually do that? I have seen that you pull one chain alot and it lifts it a little, so I’m sure that has something to do with it.

You pull the rope a foot but the weight moves only an inch. So it feels like it’s 1/12 the weight. Or it could be 5:1 or 100:1 or whatever, depending on how you set it up.
