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 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 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 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.
