The elevator has a door at each level (2,3) for access to a cabin guided in a shaft. A drive unit (20) for driving the cabin is mounted laterally outside the shaft at a position not accessible to passengers. The drive unit can be mounted beneath steps (10) in a lower floor. Alternatively, the drive unit can be mounted in the upper storey (4), esp. in the driver section. The drive unit drives the cabin via a guided supporting chain mounted on either side of the shaft and with drive and direction changing pinions and a drive shaft. |
