Abstract
A drive arrangement for an elevator car and a machine roomless elevator incorporates a machine (26) having a drive sheave (27) extending along an axis parallel to the axes of the deflection sheaves (23, 25) associated with both the counter-weight (24) and the elevator car (22). In this manner, the twisting which has occurred in the prior art is reduced or eliminated. The machine is mounted on a bedplate (18) between the guide rails. The elevator car is preferably cantilever mounted, and mounted on laterally outer surfaces of said guide rails. In this manner, the elevator car can travel vertically upwardly beyond the machine.
