    摘要： A belt for suspending and/or driving an elevator car includes a plurality of tension elements extending longitudinally along a length of the belt, at least one tension element of the plurality of tension elements having one or more tension element coating layers applied thereto. A plurality of fibers are interlaced with the plurality of tension elements forming a composite belt structure. A belt coating at least partially encapsulates the composite belt structure. A method of forming a belt for suspending and/or driving an elevator car includes forming a plurality of tension elements and applying one or more coating layers to at least one tension element of the plurality of tension elements. A plurality of fibers are interlaced with the plurality of tension elements to form a composite belt structure. A belt coating is applied to the composite belt structure to at least partially encapsulate the composite belt structure.

    摘要： 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 basalt fibers to enhance temperature resistance of the tension member. 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 basalt fibers to enhance temperature resistance of the tension member. A jacket material at least partially encapsulates the plurality of tension members.

    摘要： A hybrid rope constructed of a plurality of strands, wherein each strand is constructed of a fiber center, a jacket surrounding the fiber center, and a plurality of wires surrounding the jacket. The fiber center can be constructed of one or more high-strength synthetic fibers or yarns. The jacket can be constructed of polypropylene, thermoplastic polyurethane, high-density polyethylene, linear low-density polyethylene, nylon or other similar materials. The jacket can have a braided or woven design and adds a protective layer between the fiber center and the wires. The wires can be constructed of high-strength steel wires, galvanized steel or stainless steel. The fibers or yarns that make of the fiber center are twisted to lay right and then covered with the jacket. The wires then surround the jacket and are twisted to lay to the left. This creates a torque-balanced condition of the hybrid rope.
