Abstract
Elevator, which includes at least an elevator car and a device for moving the elevator car, preferably along guide rails, and a counterweight, and one or more ropes, which rope connects the elevator car and the counterweight and is separate from the supporting function and passes around a diverting pulley mounted on the bottom end of the elevator hoistway. The rope comprises a power transmission part or a plurality of power transmission parts, for transmitting power in the longitudinal direction of the rope, which power transmission part is essentially fully of non-metallic material.
Claims12
An elevator comprising at least an elevator car and a device configured to move the elevator car and a counterweight, and one or more ropes, which one or more ropes connect the elevator car and the counterweight and pass around a diverting pulley mounted on a bottom end of an elevator hoistway, and do not perform a supporting function of supporting and moving the elevator car and the counterweight,
- wherein each of the one or more ropes comprises a power transmission part or a plurality of power transmission parts, for transmitting power in a longitudinal direction of each of the one or more ropes, wherein each power transmission part is essentially fully of non-metallic material,
- wherein the device configured to move the elevator car comprises hoisting roping that provides the supporting function of supporting and moving the elevator car and the counterweight, which hoisting roping comprises a plurality of hoisting ropes, each of which comprises a power transmission part or a plurality of power transmission parts, for transmitting force in the longitudinal direction of the hoisting roping, wherein each power transmission part is essentially fully of non-metallic material,
- wherein a total cross-sectional area of all the power transmission parts of the hoisting roping is greater than a sum of a cross-sectional area of each power transmission part of the one or more ropes passing around the diverting pulley.
