Abstract (en)
[origin: WO2009080478A1] Elevator system (10) with a lower elevator cab (K1), an upper elevator cab (K2), at least one counterweight (12) and with supporting means (TA, TB) for supporting the lower and upper elevator cabs (K1, K2). The supporting means (TB) for supporting the lower elevator cab (K1) are guided sideways and downwards along the upper elevator cab (K2) in the elevator shaft (11). There are drive means for driving the lower and upper elevator cabs (K1, K2). A first incremental encoder (I1) that correlates with one of the supporting means (TB) and provides information on a change in the distance (D) between the lower and upper elevator cabs (K1, K2) is arranged on the upper elevator cab (K2).
