Abstract
In an elevator, a driving unit is installed at the top of an elevator shaft above a counterweight. Traction sheaves engage with ropes and are rotated by the driving device. These traction sheaves are positioned close to wall surfaces of the elevator shaft, that are adjacent to its wall surface facing the counterweight. The traction sheaves are also positioned outside the horizontally projected plane of a car.
