Abstract
The suspension system for an elevator car provides ropes that converge on the car close to a vertical line containing the center of gravity of the car. The ropes thus impart very little lateral or torsional movement to the car whereby a smoother ride results. The ropes are mounted on a set of sheaves which are arranged in a V-shaped array. The ropes thus fed to the counterweight are spread farther apart than those fed from the sheaves to the car.
