On a winch? That’s an intriguing idea.

   How many scissors are there in your lift? On the real ones I’ve seen they often have a hydraulic cylinder going from the bottom scissor to the top one, you gain some mechanical adveantage doing it that way, but it may be difficult to emulate in LEGO.

Just one scissor.

Update: I ended up using string and it worked beautifully! Well, it has weight distribution issues (one side goes up before the other) but I’ll work on that later...
