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.
