Abstract (en)

[origin: WO2009080538A1] The invention relates to an elevator system (10) comprising two elevator cars (K1; K2) arranged one over the other, but that can travel independently of each other. Both elevator cars (K1; K2) are suspended on suspension and traction mechanisms (102; 202) and each coupled to a counterweight (G1; G2). Both elevator cars (K1; K2) have a lower cable (110; 210), wherein the two lower cables (110; 210) are tensioned by separate tension devices. The lower cable (110) of the first, lower elevator car (K1) is fastened to the first elevator car (K1) and the first counterweight (G1). The lower cable (210) of the second elevator car (K2) is guided at the second elevator car and at least one of the two lower cable ends thereof (210.1, 210.2) is secured by a weighted body (214, 224) secured in place with play and/or free-floating.
