An elevator apparatus is provided with an elevator path having a restricted height. Under a roping ratio of 1:1, a thin driving unit having a traction sheave and a driving mechanism is positioned between an inner wall of the elevator path and a space occupied by an elevator car rising and falling in the elevator path . One end of a suspension rope is fixed to the elevator car in a position below a ceiling of the elevator car . With the arrangement, the car can move close to the ceiling of the elevator car effectively. Further, it is possible to reduce respective heights of the elevator path and a building equipped with the elevator apparatus.

Traction type elevator apparatus

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.

Elevator

An elevator including a cage configured to move up and down in a shaft along a guide rail, a plurality of car sheaves installed at a bottom of the cage, a cable placed around the car sheaves and configured to suspend the cage, a hoisting machine having a traction sheave configured to drive the cable, a base extending in a width direction of the cage and configured to support the car sheaves, and a first elastic member disposed between the cage and the base so as to attenuate vibration transferred to the cage.
