    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.

    Abstract: An elevator system includes a hoistway, an elevator car movable along the hoistway, and one or more belts operably connected to the elevator car to propel the elevator car along the hoistway. A belt of the one or more belts includes one or more tension elements extending along a belt length, and a jacket at least partially encapsulating the one or more tension elements. The jacket includes a jacket base formed from a first material and one or more insert layers embedded in the jacket base material. The one or more insert layers have a corrugated shape along the belt length, and are formed from a second material different from the first material.

    Abstract: A load bearing member (30) for a lifting and/or hoisting system includes a plurality of tension members (32) arranged along a width of the load bearing member. Each tension member includes a plurality of load carrying fibers (34) arranged to extend in a direction parallel to a length of the load bearing member and a matrix material (36) in which the plurality of load carrying fibers are arranged. The load bearing member further includes a lateral layer (40, 42) and a jacket material (50) at least partially encapsulating the plurality of tension members.

    Abstract: A belt for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members arranged in a lengthwise direction and a jacket substantially retaining the plurality of tension members. The jacket includes a traction portion, a back portion, and an inner portion between the traction portion and the back portion. The traction portion is formed from a first material and the inner portion is formed from a second material having an increased fire resistance compared to the first material. A method of forming an elevator system belt includes arranging a plurality of tension members in a lengthwise direction and securing the plurality of tension members in a jacket by at least partially enclosing the plurality of tension members in the jacket. The jacket includes a traction portion, a back portion, and an inner portion having a greater fire resistance than the traction portion.

    Abstract: A method of fault detection of a belt or rope includes connecting a fault detection unit to at least a portion of a belt or rope including a plurality of wires arranged in a plurality of strands and/or cords. At least the portion of the belt or rope is subjected to an AC voltage of high frequency range and an electrical impedance of the portion of the belt or rope is measured via the fault detection unit. Using at least the measured electrical impedance of the portion of the belt or rope, a fault condition of the belt or rope is determined.
