<p>The invention relates to an elevator system with a number of elevator cars inside a shaft. A second elevator car (14) is placed underneath a first elevator car (12), and a drive (28, 44) with a driving pulley (22, 41) as well as at least one cable line (18, 30, 31), which is guided over the driving pulley (22, 41) and via which the elevator car (12, 14) is connected to the counterweight (20, 33), is assigned to each elevator car (12, 14). The second elevator car (14) is held with a suspension ratio of 1:1 and is connected to counterweight (33) via two cable lines (30, 31), which are assigned to different sides of the second elevator car (14) and which are guided over the driving pulley (41) of the second elevator car (14). In order to improve the design of the elevator system so that both cable lines (30, 31) of the second elevator car (14) reach their maximum permissible rate of wear at nearly the same time, thus, in order to reduce the operating costs, the invention provides that the elevator system (10) has a cable guiding device that equally loads both cable lines (30, 31) of the second elevator car (14).</p> |
