Thanks for your comments. I was referring to skyscraper elevators only, but rndpndp and peter are right, there are other types of elevators, depending on the high of the building and the waits they must carry.
And no, I don;t work with elevators but with science museums, where we explain these physics to curious people.
I like this, but it's not entirely true. Elevator motors are really good at moving ropes great distances, and complex pulleys are often used in short rise buildings, so that, given a longer elevator cable, a smaller motor can be used. Of course, extra ropes is cheaper than a great big traction motor.
Elevators have many different roping, 1:1 which is car to counterweight is your example, there are many other 2:1, 4:1, underslung, doublewrap... and the counterweight is also heavier than the car by aprox 10%
