| 摘要 |
The invention relates to an elevator unit including an elevator car which is movable in an elevator shaft and is equipped with a braking device and a catching device encompassing catching elements. The elevator unit further includes a system for detecting signals used for determining an absolute position of the elevator car, a control circuit for detecting signals used for determining the speed or deceleration of the elevator car, and a circuit for evaluating the signals of the detection system and the control circuit. Based on the input signals, the evaluation circuit evaluates whether the speed of the elevator car lies within a predefined interval in the determined position and causes the braking device to be actuated via a first output of the evaluation circuit and/or the catching device to be triggered via a second output of the evaluation circuit according to the result of the evaluation.
