ABSTRACT:
Movement of the elevator is derived from a linear motor forming a part of the counterweight assembly of the elevator. Overhead guide sheaves carry the ropes which connect the counterweight with the cab. The guide sheaves are mounted laterally of the cab on both sides thereof whereby there are no sheaves directly above and in line with the cab. The cab mount beam connects to the center of gravity of the cab but lies skew to the lateral vertical plane of symmetry of the cab so that the ropes will be offset fore and aft of the guide rails of the cab.
