Elevator carriage with horizontal balancing system

Abstract

The cabin (1) is moved vertically in an elevator shaft (9) with vertical guide rails (4) and has spring-mounted rollers (3.1.1 - 3.4.1) for guiding the cabin along the rails and an arrangement for carrying out weight balancing in the event of eccentric loading of the cabin with a hydraulic balancing system (6).

Description

technical field [0001] The invention relates to an elevator car with a balancing system for balancing the weight during eccentric loading and to a method for weight balancing. Background technique [0002] Elevator installations generally have an elevator shaft in which guide rails for guiding the elevator car are mounted and arranged. The elevator car has rollers that roll along guide rails. In order to improve ride comfort, to compensate for unevenness of the guide rail and to achieve an optimal guidance of the eccentrically loaded elevator car, the rollers are elastically suspended. Springs, especially those used in high-power elevators, generally have a progressive spring characteristic, which should be designed such that they promote a soft spring to the elevator car at small spring deflections. In the case of large spring deflections, the spring operates in the range of a hard characteristic curve, absorbing relatively large forces. [0003] When an elevator car wit...
