ABSTRACT:
Movement of the cab of an elevator is guided along hoistway guide rails by a guide assembly that shares loads imposed by the cab between guide shoes and guide rollers. There is one guide shoe/guide roller sub-assembly mounted above and below the cab for engagement with each guide rail. In each sub-assembly, the guide shoe and guide roller are mounted on opposite ends of a pivoting arm. The guide rollers engage opposite sides of the guide rail blade, and the geometry of the system is such that loads are proportionally shared by the guide shoes and guide rollers.
