Re: Elevator Design Help

Wire rope? Does it wrap around the worm, or is it simply attached to a pulley?
If it's the latter, reducing the diameter of the pulley should act as a way to reduce weight and speed. We are using a 1.08"-ish pitch diameter timing belt pulley for ours.
IMO ditch the worm gear entirely and just make it a two-stage versaplanetary. We were running fine on a 28:1 reduction on an RS-775 (at least for a few totes) so a cim with a two-stage versaplanetary could suit you well.
Best of luck!
