Abstract: A suspension member for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members extending along a length of the suspension member including a plurality of fibers extending along the length of the suspension member bonded into a polymer matrix. A jacket substantially retains the plurality of tension members. The suspension member is configured to be deformed at a suspension member end to allow for installation of the suspension member end into a termination assembly of the elevator system. A method of installing a suspension member of an elevator system into a termination assembly includes deforming a suspension member end and reforming it to a selected shape, inserting the suspension member end into the termination assembly and curing and/or hardening it, and applying a load thereto or to the socket or the wedge to secure the suspension member end in the termination assembly.

Abstract: A method of forming a belt for suspending and/or driving an elevator car includes arraying a plurality of tension elements longitudinally along a belt and interlacing a plurality of warp fibers and a plurality of weft fibers with the plurality of tension elements to form a composite belt structure. A coating is applied to at least partially encapsulate the composite belt structure. The coating includes a base coating material and at least one additive mixed with the base coating material to improve an operational characteristic of the belt.

Abstract: An illustrative example embodiment of an elevator load bearing member includes a plurality of load bearing cords and a woven fabric including a plurality of warp yarns along a length of the load bearing member and a plurality of weft yarns transverse to the length of the load bearing member. The woven fabric includes a central portion and lateral edge portions extending along the length of the load bearing member. The central portion includes the load bearing cords interlaced with the woven fabric. The lateral edge portions each include terminal ends of the weft yarns. The central portion has a first plurality of warp yarns situated between laterally outermost ones of the cords. The lateral edge portions have a second plurality of warp yarns between the laterally outermost ones of the cords and the terminal ends of the weft yarns.
