A belt for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members spaced from each other along a width of the belt and extending longitudinally along a length of the belt. A jacket at least partially envelopes the plurality of tension members and forms at least one outer belt surface along a width of the belt. A groove is located in the at least one outer belt surface extending longitudinally along the length of the belt.

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 plurality of fibers interlaced with the plurality of tension elements forming a composite belt structure. A coating at least partially encapsulates the composite belt structure to improve two or more operational characteristics of the belt. A method of forming a belt for suspending and/or driving an elevator car includes forming a plurality of tension elements and arraying the plurality of tension elements longitudinally along a belt. A plurality of fibers are interlaced 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 to improve at least two operational characteristics of the belt.

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.

The present invention relates to an engineered fiber bundle for reinforcement of composite materials. Specifically, the engineered fiber bundles of the present invention enhance the tensile behavior of the composites reinforced with the fiber bundles. Methods of making the same are further provided.

A belt for an elevator system including a plurality of tension members arranged along a belt width and a jacket material at least partially encapsulating the plurality of tension members defining a traction surface interactive with a traction sheave of an elevator system and a back surface opposite the traction surface. The back surface includes a belt guide feature extending along a belt length and interactive with a complimentary guide sheave feature of a guide sheave of the elevator system to orient the belt to a selected location during operation of the elevator system.

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.

A method of surface treating a load-bearing member comprising a tension member and a polymer jacket around the tension member is disclosed. According to the method, a liquid composition including water, a water-soluble organic polyol or a water-soluble organic polymer, and a surfactant is applied to a surface of the polymer jacket.

A belt-shaped rope of a hoisting device, the rope being substantially larger in its width-direction than thickness-direction, and comprising two or more load bearing members; a coating forming an outer surface of the rope, in which coating the two or more load bearing members are embedded, wherein the two or more load bearing members are oriented to extend parallel with longitudinal direction of the rope adjacent each other in width direction of the rope such that a gap is formed in width direction between load bearing members next to each other, the coating extending into the gap. The coating comprises a first coating portion between load bearing members next to each other, and a second coating portion forming an outer side of the rope facing in thickness direction of the rope, and in that the material of the first coating portion is substantially harder than the material of the second coating portion.

A wire including a wire body that is made of metal, and a protector that is made of resin, that covers an outer periphery of the wire body, and that is integrally molded with the wire body.

Draw tape for cables including an elongated flexible element made of a helical multifilament rope composed of three filaments or strands helically wound about a common longitudinal axis. According to an additional feature, the rope is hammered. Still according to an improvement, the rope is externally covered by a jacket.
