Abstract: An elevator brake wedge is provided and includes an elongate body having first and second generally opposed major surfaces and first and second generally opposed minor surfaces. The second minor surface has a greater length than the first minor surface. Each of the first and second major surfaces extends between corresponding first and second ends of the first and second minor surfaces, respectively. The second major surface defines low-friction film securing grooves extending from a plane of the second major surface into the elongate body.

Abstract: A tension member for a lifting and/or hoisting system includes a core including a plurality of load carrying fibers arranged in a matrix material, and an outer layer secured to the core including a plurality of outer fibers arranged around a perimeter of the core. The outer layer includes one or more outer fibers arranged off-axis relative to the load carrying fibers of the core. A method of forming a tension member for an elevator system includes arranging a plurality of load carrying fibers along a length of the tension member, retaining the plurality of load carrying fibers in a matrix material to define a core, and enclosing the core in an outer layer including a plurality of outer fibers arranged around a perimeter of the core. The outer layer includes one or more outer fibers arranged off-axis relative to the load carrying fibers of the core.

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.

Abstract: A belt for suspending and/or driving an elevator car includes a plurality of tension elements extending longitudinally along a length of the belt, and a jacket at least partially encapsulating the plurality of tension elements. The jacket defines a traction surface of the belt configured to be interactive with a drive sheave and a back surface opposite the traction surface. The jacket is formed from a first material. One or more material strips are located at one or more of the traction surface or the back surface to improve one or more operational characteristics of the belt. The one or more material strips formed from a second material different from the first material.
