Abstract: A belt for suspending and/or driving an elevator car includes a plurality of cords. Each cord includes a plurality of wires and at least one yarn thread disposed at an outer periphery of the plurality of wires. An elastomeric jacket substantially retains the plurality of cords. The at least one yarn thread is configured to promote adhesion of the elastomeric jacket to the plurality of cords and reduce fretting of the plurality of wires. A method of forming a belt includes arranging a plurality of wires into a cord, arranging one or more yarn threads at an outer periphery of the plurality of wires, arranging a plurality of cords into a selected arrangement and applying an elastomeric jacket to the cords to retain the cords. The one or more yarn threads are configured to promote adhesion of the elastomeric jacket to the cords and reduce fretting of the wires.

Abstract: An exemplary assembly includes at least one elongated tension member. A jacket covers at least some of the tension member. The polymer jacket comprises a polymer material including a melamine based geometry stabilizer that facilitates maintaining the jacket material near the tension member if the assembly is subjected to a high temperature condition.

Abstract: An illustrative method of making an elevator load bearing member having at least one elongated tension member at least partially covered by a jacket includes mixing a flame retardant with a polymer material. The flame retardant is selected from a group consisting of (i) a halogen-free melamine based intumescent comprising melamine cyanurate, melamine-phosphate, melamine pyrophosphate or melamine polyphosphate in an amount up to about 20% by weight of the thermoplastic polymer or (ii) a filled polymer having a nanoscale filler chemically bonded to a matrix phase. Applying the mixed flame retardant and polymer material to the tension member forms a jacket of a desired shape.

Abstract: An exemplary elongated elevator load bearing member includes a plurality of tension elements that extend along a length of the load bearing member. A plurality of weave fibers transverse to the tension elements are woven with the tension elements such that the weave fibers maintain a desired spacing and alignment of the tension elements relative to each other. The weave fibers at least partially cover the tension elements. The weave fibers are exposed and establish an exterior, traction surface of the load bearing member.

Abstract: 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.

Abstract: An illustrative example method of making an elongated load bearing member includes providing a plurality of tension elements. A plurality of weave fibers are woven together with the tension elements to thereby establish a weave. A traction surface is established on at least one side of the load bearing member. The traction surface is defined by the weave fibers. Coating the weave fibers with a compressible coating provides an exterior surface texture defined at least in part by the weave fibers.
