摘要:
Elevator, preferably an elevator without machine room. In the elevator, a hoisting machine engages a set of hoisting ropes by means of a traction sheave. The set of hoisting ropes comprises hoisting ropes of substantially circular cross-section. The hoisting ropes support a counterweight and an elevator car moving on their respective tracks. The hoisting rope has a thickness below 8 mm and/or the diameter of the traction sheave is smaller than 320 mm. The contact angle between the hoisting rope or hoisting ropes and the traction sheave is larger than 180°.
