A supporting and drive belt including a belt body or sheathing which encloses tensile carriers. The running surface of the belt can be flat and parallel to the belt back or have trapezium-shaped or semicircular ribs and grooves, wherein the profile of a drive pulley or of a deflecting pulley is approximately complementary to the running surface of the belt. One or more tensile carriers are provided for each rib, wherein the tensile carriers are laid or stranded alternately in the 'Z' direction and the 'S' direction.

Flat-belt-like supporting and drive means with tensile carriers

A synthetic fiber cable has the strands of a strand layer mutually spaced apart. With the mutual spacing, the strands of the outer strand layer can move radially in the direction of the cable center and exert a radial pressure on the strands of the first inner strand layer. The radial pressure is passed on from the strands of the first inner strand layer to the strands of the second inner strand layer. The radial pressure is passed on from the strands of the second inner strand layer to the core strand. The radial pressure increases inwardly from strand layer to strand layer. The soft cable sheathing does not act as a support between the strands in circumferential direction.

Synthetic fiber cable and elevator installation with such a synthetic fiber cable

In an elevator installation, an apparatus and a method use a support end connection for fastening a support device to an elevator car, a counterweight and/or a building. The support device has at least one cable or cable strand enclosed by a cable casing and is held in a wedge pocket by a wedge. The cable casing is formed of thermoplastic material or an elastomer and the cable or the cable strand is glued to, fused together with or mechanically connected with the cable casing in the region of the support end connection. A friction force transmitted from the support end connection to the cable casing can then be directly passed on to the load-bearing core of the support device, to the cables or to the cable strands. The tolerable tension force in the support device is increased. The support device is preferably a multiple cable.
