A suspension and transmission device for use with an elevator system comprises one or more strips that provide load carrying, transmission or traction, and load carrying redundancy or safety functions for the elevator system. In one version a single strip comprised of polymer and composite materials provides these functions. In another version multiple strips comprised of polymer and composite materials provide these functions. In another version, a strip comprises a hollow interior portion. In another version one or more strips incorporate materials that can be detected when using the strip to monitor the condition of the one or more strips.

A travelling cable of an elevator, more particularly of a passenger transport elevator and/or freight transport elevator, includes a protective envelope, conductors for transmitting electrical energy and data between the elevator car and the elevator hoistway, and one or more load-bearing bearer parts of essentially the length of the travelling cable for fixing the travelling cable at its first end to the elevator car and at its second end to the elevator hoistway, and which bearer part includes glass-fiber reinforcements and/or aramid-fiber reinforcements and/or carbon-fiber reinforcements and/or polybenzoxazole-fiber reinforcements and/or polyethylene-fiber reinforcements and/or nylon-fiber reinforcements in a polymer matrix material. An elevator includes the travelling cable.

A cobalt-free steel cord-rubber composite article includes, in sequence, a steel cord core, a steel cord coating, and a rubber layer. The steel cord coating contains from about 61 wt % to about 66 wt % copper, from about 3.5 wt % to about 6.5 wt % iron, and a balance of zinc and unavoidable impurities. The rubber layer is formed from a rubber compound including 100 phr of at least one elastomer; sulfur; about 20 phr to about 100 phr of at least one filler; about 2 phr to about 15 phr of zinc oxide; and about 0.5 phr to about 3.0 phr of at least one accelerator, containing no cobalt and no resin.

A method for producing a rope, wherein fiber bundles are applied with a liquefied matrix material upstream of and/or at a twisting point to form fiber strands, and are embedded into the liquefied matrix material during stranding, by which fiber strands a fiber core of the rope is formed and wires or wire strands are wound about the fiber core. The matrix material of the fiber strands is hardened after the stranding, and the fiber strands are subsequently stranded directly with one another without further application to form the fiber core. Preferably the fiber strands are heated, during or after the stranding thereof to form the fiber core, so that the matrix material softens at least individual fiber strands, preferably all the fiber strands, another of the fiber strands is connected with the matrix material, and is subsequently hardened, forming an integral bond with one another.

A product comprising a plurality of interlaced yarns wherein at least a first yarn having a tensile strength, having a value TS in N/tex, said first yarn containing a plurality of UHMWPE fibers having a titer, having a value T in den, wherein the ratio T/TS is at least 5 den.tex/N. The tensile strength is obtained by adjusting the drawing ratio or the UHMWPE filaments/fibers accordingly. The product shows resistance to abrasion. The product can be a rope or round slings, comprising a sheath/jacket comprising said first yarn.
