Abstract: An automatic handrail tensioning system and a method for adjusting the tension degree of a handrail, and belongs to the technical field of escalators. The automatic handrail tensioning system of the present invention comprises: a sensor for detecting information that can reflect a tension degree of the handrail; a controller for determining the tension degree information of the handrail according to the information detected by the sensor, and generating a corresponding control instruction for adjusting the tension degree of the handrail based on the tension degree information; and an actuator for driving a tensioning device to adjust the tension degree of the handrail based on the control instruction.

Abstract: A load bearing tension member for an elevator system includes a plurality of tension elements arrayed across a tension member width. The tension elements are offset from a tension member central axis, the central axis bisecting a tension member thickness and extending across the tension member width. The tension elements include a plurality of fibers extending along a length of the tension element, and a matrix material in which the plurality of fibers are embedded. A jacket at least partially encapsulates the plurality of tension elements.

Abstract: A belted elevator system (10) includes a hoistway (14) and an elevator car (12) suspended in the hoistway (14) via a suspension member (16) and drivable along the hoistway (14). The suspension member (16) is routed over a plurality of sheaves (18). A sheave (18) of the plurality of sheaves includes a shaft (36) defining a central axis of the sheave (18), the sheave (18) rotatable about the central axis. A sheave outer member (38) is operably connected to the shaft (36) and rotatable about the central axis. The sheave outer member (38) includes a sheave outer surface (44) interactive with the suspension member (16). The sheave outer member (38) is formed from a molded plastic material.

Abstract: A unitized segmented sheave assembly is provided. The unitized segmented sleeve assembly includes sheaves arrayed in a side-to-side formation and respectively comprising bearings and an exterior running surface and spacers interleaved between neighboring sheaves. Respective inner races of the bearings of each sheave and respective interior portions of each spacer cooperatively form an interior annular surface. The unitized segmented sheave assembly further includes a sleeve disposable in abutment with the interior annular surface.

Abstract: A termination device for a suspension member of an elevator system includes a housing including a socket defined by two face plates and two side plates. At least one of the face plates and at least one of the side plates are integrally formed. A wedge is receivable within the socket with the suspension member. The wedge is configured to cooperate with the housing to apply a clamping force to the suspension member in response to an axial load acting on the suspension member.
