Re: Elevator counterweight / constant spring and ability to lift different number of

Instead of trying to counterbalance, think instead of applying a friction brake of some sort. Try thinking about how you brake a bicycle tire, and see if you can do something like that with your spool that lifts the elevator. Pneumatic would be a great way to generate that braking force without burning out a motor!
