Abstract: A multi-stage elevator car has equipment for fine positioning of the cars wherein the car thresholds are positionable at the level of the floor thresholds. Adjusting equipment operating on the principle of a differential block and pulley is provided for fine positioning of the cars, the equipment including an endless cable guided over deflecting rollers arranged at the main frame of the multi-stage car and over deflecting rollers arranged at the cars, wherein the cars execute vertical movements of opposite sense.
Abstract: An elevator in which the elevator car is suspended by means of hoisting ropes consisting of a single rope or several parallel ropes, said elevator having a traction sheave which moves the elevator car by means of the hoisting ropes. The elevator has rope portions of the hoisting ropes going upwards and downwards from the elevator car, and the rope portions going upwards from the elevator car are under a first rope tension (T1) which is greater than a second rope tension (T2), which is the rope tension of the rope portions going downwards from the elevator car, and that the elevator comprises a compensating system for keeping the ratio (T1/T2) between the first and the second rope tensions substantially constant.
