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.

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 braided rope includes a plurality of braided strands comprising twisted yarns. Each of the twisted yarns includes a blend of first fibers and second fibers. The first fibers are high modulus polyethylene (HMPE) fibers and the second fibers may be lyotropic polymer filaments, thermotropic polymer filaments, or polyphenylene benzobisoxazole fibers. The first fibers can have a creep rate of no more than 3.0×10.sup.−8 percent per second at 20° C. while subjected to a stress of 5.0 grams/dtex. The first fibers can have a creep rate of no more than 1.0×10.sup.−7 percent per second at 20° C. while subjected to a stress of 7.5 grams/dtex.

A belt for an elevator system is provided having a core and an elastomeric sheath positioned over the core. An elastomer and phosphonate blended bonding agent adheres the core to the sheath.

A belt includes one or more tension members extending along a length of the belt, and a jacket at least partially enclosing the plurality of tension members. The jacket includes an elastomeric material and a plurality of reinforcing elements located in the elastomeric material to improve fatigue cracking performance of the belt. An elevator system includes a hoistway, an elevator car located in the hoistway, and an elevator belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The elevator belt includes one or more tension members extending along a length of the belt and a jacket at least partially enclosing the plurality of tension members. The jacket includes an elastomeric material and a plurality of reinforcing elements located in the elastomeric material to improve fatigue cracking performance of the belt.

An elevator tension member is presented that has one or more steel cords as strength members that are encased in a jacket of thermoplastic polyurethane elastomer. The thermoplastic polyurethane elastomer is selected on the basis of its thermal properties in that the glass transition temperature of the hard phase (Tg HS) is above 90° C. In preferential embodiments that thermoplastic polyurethane elastomer has a crystallisation temperature (Tg) that is at least 20° C. higher than Tg HS. In other preferential embodiments the sum of Tg HS and Tc is higher than 200° C. Such thermoplastic polyurethane elastomers exhibit an unexpected increase in useful lifetime when compared to conventionally used polyurethanes. Moreover the invention provides a simple method to select an appropriate thermoplastic polyurethane elastomer.

A belt (30) for suspending and/or driving an elevator car (14) includes a plurality of tension elements (32) 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 (46) applied thereto. A plurality of fibers are interlaced with the plurality of tension elements forming a composite belt structure. A belt coating (44) at least partially encapsulates the composite belt structure.

The disclosure provides a sling including a sleeve, a first eye formed by a first splice, and a second eye formed by a second splice. The sleeve includes braided strands and has a first end portion, a second end portion, and an intermediate portion between. The sleeve also defines a hollow inner volume. The first splice is made by the first end portion extending into and along part of the hollow inner volume proximate the first eye. The second splice is made by the second end portion extending into and along part of the hollow inner volume proximate the second eye. A hollow load bearing portion is defined in the intermediate portion between the first splice and the second splice.

The invention relates to a rope (1) made of textile fibre material, which is characterized by the combination of features whereby

a) the load-bearing fibre material of the rope (1) consists of high-strength synthetic fibres

b) the rope (1) is in the form of a spiral strand rope

c) the rope (1) has at least two, preferably at least three concentric load-bearing strand layers (3,4,5)

d) the individual strands (7,8,9,10,11,12) of the strand layers (3,4,5) are movable with respect to one another

e) the degree of filling of the rope (1) with textile fibre material is ≧75%, preferably ≧85%

f) the outermost ply (5,6) of the rope has a coefficient of frictionμ with respect to steel of μ<0.15.

A belt for an elevator system includes 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, a back surface opposite the traction surface together with the traction surface defining a belt thickness, and two end surfaces extending between the traction surface and the back surface defining the belt width. A metallic coating layer is applied via deposition of solid particles over at least one end surface of the two end surfaces.
