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: 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 belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt. Each tension member includes a plurality of first fibers, and a plurality of second fibers different from the first fibers dispersed into the first fibers. A jacket material at least partially encapsulates the plurality of tension members. An elevator system includes a hoistway, an elevator car located in the hoistway and movable therein, and a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt. Each tension member includes a plurality of first fibers and a plurality of second fibers different from the first fibers dispersed into the first fibers.

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: A belt and sheave assembly for an elevator system includes a sheave having a plurality of tracking grooves laterally spaced across a sheave width, and a debris channel located in a tracking groove of the plurality of tracking grooves defining a radially inwardmost extent of the tracking groove. The assembly further includes a belt having a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, a jacket at least partially enclosing the tension members, the jacket defining a side of the belt configured to interface with the sheave, and a plurality of tracking features extending from the side of the belt. The tracking features are laterally spaced across the belt width. Each tracking feature is configured to be received in a tracking groove, and each tension member is laterally offset from each of the tracking features.
