You’re in a difficult spot there. DON’T JUMP! We’ll send in a special team to rescue you.
Hunker down, smoke ‘em if you got ‘em.
I've ridden one. It was a fun and interesting experience. The belt, with handles and step platforms, came up at a constant speed from a hole in the floor of the factory.
Grab the handle, step on the platform, and up you go! When you get to the appropriate floor, step off.
Hint: Don't try for the round trip. On the way down, you're supposed to stand on the other side of the platform.
