Elevator Lift

[farmersvilleRob]

Well your looking at linear motion. You want linear motion. There are seperate ways of doing this:

Actuators! Some actuators are actually designed for linear motion such as pneumatics and linear servo actuators. Now, if your lifting off the floor, linear wouldn't work because it would get in the way of anything in the elevator or the elevators path.

Motors: motors, though circular motion, can be converted to linear with common things like a rack and pinion. All have their downsides, but when doing an elevator with a power source that's out of the way, a circular to linear conversion is the best considering if you engineer it right, it could scale the whole 5 feet maximum (or 84 inches depending on your side of the field). I don't know how to do this, we trashed the elevator details for other details, lol try googling rotational to linear.

Speed, RPM is what you need, but for strength (countering gravity), torque is the best. I would stay away from Igus because their parts are known to be flimsy and break easy. I wouldn't do conveyor either because it can jam easy. It's a true engineering problem which I stay away from, lol but there are LOADS of options.
