ABSTRACT:
The escalator handrail is provided with increased lateral flexibility by forming it with a guide rail spanning web which is elliptical in cross-section. Adjacent internal reinforcement cables are positioned in slightly vertically offset horiozntal planes so as not to unduly hinder lateral flexure of the handrail. The handrail's increased flexibility results in less frictional drag on the guide rail, and adapts the handrail for use with helical escalator assemblies and provides improved performance in conventional rectilinear escalators as well.
