Abstract: A transmission belt for driving and/or supporting an elevator car has a longitudinally extending body including an area tensile layer reinforced by chemical fibers. The belt can have a flat friction layer or a friction layer including alternating longitudinally extending wedge-shaped ribs and grooves. Transverse grooves can be formed across the width of the longitudinally grooved friction layer.

Abstract: An elevator system includes at least one drive with at least one drive pulley, an elevator car and at least one counterweight as well as flat-belt-like support for the car and the counterweight. The elevator car and the counterweight have at least one support roller. The flat-belt-like support means together with the drive pulley and the support rollers form at least one 2:1 suspension system for the car and the counterweight. The flat-belt-like support can be a wedge-ribbed belt or a cogged belt.

Abstract: A wedge-ribbed belt supports an elevator car in a cantilevered mode and engages a drive pulley of a drive mounted at the head of an elevator shaft. The belt has a running surface facing the drive pulley with a plurality of ribs and grooves extending in parallel in a longitudinal direction of the belt. The ribs and grooves can be triangular-shaped or trapezium-shaped in cross section. A plane of the drive pulley is arranged vertically and at right angles to a car wall at a counterweight side of the elevator car.

Abstract: A wedge-ribbed belt supports an elevator car by underlooping and engages a drive pulley of a drive mounted at the head of an elevator shaft. The belt has a running surface facing the drive pulley with a plurality of ribs and grooves extending in parallel in a longitudinal direction of the belt. The ribs and grooves can be triangular-shaped or trapezium-shaped in cross section. A plane of the drive pulley is arranged vertically and at right angles to a car wall at a counterweight side of the elevator car and approximately in a middle of a car depth with a vertical projection of the drive pulley onto the counterweight side being outside a vertical projection of the counterweight side. A part of a vertical projection of the drive motor is superimposed on the vertical projection of the counterweight side of the elevator car.

Abstract: A guide rail arrangement for avoiding the costly and time-consuming aligning of the guide rails for a counterweight and an elevator car includes guide rails fastened to a mounting bracket connected with the shaft wall at the door side. The guide rails of two counterweights are held by double claws that are fastened to the mounting bracket by only one screw.
