The invention relates to an elevator installation, comprising a shaft, in which at least one elevator car can be moved up and down in a vertical direction and is coupled to a counterweight by means of a cable assembly or belt assembly, wherein the cable assembly or belt assembly has at least one cable segment or belt segment whose horizontal deflection can be limited by at least one limiting element. According to the invention, in order to further develop an elevator installation in such a way that damage to a limiting element can be avoided in the event of a horizontal deflection of a cable segment or belt segment, at least one limiting element according to the invention is designed as a limiting roller, which is supported laterally adjacent to a cable or segment or belt segment in such a way that the limiting roller can be rotated about an axis of rotation and which can be caused to rotate by a controllable rotary drive in dependence on the speed and the direction of motion of the cable segment or belt segment arranged laterally adjacent to the limiting roller in relation to the axis of rotation of the limiting roller.

The invention relates to an elevator system (10) comprising a vertical shaft (12) and at least two cars (14, 16) which are arranged one over the other in the shaft (12) and each of which can be moved upwards and downwards. A first car (14) is coupled to a first drive (20) and to a first counterweight (25) via first support means (18), and a second car (16) is coupled to a second drive (28) and a second counterweight (36) via second support means (26). The elevator system also comprises a machine area (38) which adjoins the shaft (12) and which is spatially separated from the shaft. The first drive (20) is arranged outside of the shaft (12), and the second drive (28) is arranged at least partly within the shaft (12).

The invention relates to an elevator installation having a shaft, in which a first elevator car and a second elevator car that is arranged below the first elevator car can be moved upwards and downwards in the vertical direction separately from each other. Each elevator car is coupled to a counterweight by means of a cable or belt arrangement. At least one cable or belt arrangement has two cable or belt sections, by means of which one of the elevator cars is coupled to a counterweight and which extend laterally along the other elevator car. In order to prevent an elevator car being adversely affected by cable or belt oscillations, the elevator installation according to the invention has at least one limiting member, which is held in a predefined position in the shaft and is assigned to a cable or belt section and has at least one limiting element, which can be moved to and fro between a limiting position and a release position depending on the position of the elevator car that is coupled to the counterweight by means of the associated cable or belt section. In the limiting position, the limiting element can be positioned on the side of the cable or belt section that faces the elevator car, and in the release position, the limiting element releases said side.

The invention relates to a method for operating a lift system (100) which comprises at least two cars (120, 121) in a lift shaft (110), a first car (120) which is traveling or is meant to travel in the direction of a second car (121) being moved in accordance with a travel curve such that a distance (d) between the first car (120) and the second car (121) can be controlled to an adjustable minimum distance. The invention also relates to a control system (130) for such a lift system (100), and to a lift system (100).
摘要:
The present invention relates to a method for operating a lift system comprising a car which is moved in a lift shaft, wherein the car stops at a floor, wherein the car comes to a standstill at the floor and the flow of energy is interrupted and/or the service brake is activated in the process, wherein, in the case of the flow of energy being interrupted, a flow of energy of a drive of the car is interrupted, and wherein, in the case of the service brake being activated, a service brake is activated, and wherein, if necessary, a position of the car is adjusted at the floor, wherein the position of the car in the lift shaft is adapted relative to the floor during the adjustment, wherein at least one operating parameter which relates to a change in loading of the car is detected (202) and it is determined whether there is a need for adjustment (203) at the floor, depending on the at least one operating parameter at least before the car comes to a standstill.
