Abstract
Lift system (10) with a lower lift cage (K1), an upper lift cage (K2), at least one counterweight (12), and support means (TA, TB) for supporting the lower and upper lift cages (K1, K2). The support means (TB) for supporting the lower lift cage (K1) are led downwardly in the lift shaft (11) laterally along the upper lift cage (K2). Drive means for driving the lower and upper lift cages (K1, K2) are present. Arranged at the upper lift cage (K2) is a first incremental transmitter (I1) which interacts with one of the support means (TB) and supplies information about a change in the spacing (D) between the lower and upper lift cages (K1, K2).
Claims11
Lift system (10) with
- a lower lift cage (K1),
- an upper lift cage (K2),
- at least one counterweight (12),
- support means (TA, TB) for supporting the lower and upper lift cages (K1, K2), wherein at least one support means (TB) for supporting the lower lift cage (K1) is led downwardly in the lift shaft (11) laterally along the upper lift cage (K2),
- drive means for driving the lower and upper lift cages (K1, K2), and
- a common lift shaft (11) in which the upper lift cage (K2) and the lower lift cage (K1) vertically move independently of one another,
- characterised in that
- arranged at the upper lift cage (K2) is a first incremental transmitter (I1) which interacts with a support means (TB) for supporting the lift cage (K1) and supplies to the upper lift cage (K2) information about a change in the spacing (D) between the lower and upper lift cages (K1, K2).
