Abstract:
1. A lift facility in a lift shaft, comprising: at least one lift car including at least one braking device; the at least one braking device comprising at least one braking module to cooperate with a device that moves relative to the at least one braking module, and the at least one braking device having a catch which is movable between a first variant and a second variant of a first operating position and a second operating position; the catch, in the first variant of the first operating position, is connected to the at least one braking module so that the catch holds the at least one braking module away from the device at a release gap; the catch, in the second variant of the first operating position, is released from the at least one braking module with a release force so that the at least one braking module is in contact with the device; the catch, in the second operating position, is separated from the at least one braking module when electrical power is interrupted so that the at least one braking module is in contact with the device; at least one force module or energy storage to provide a braking force to the at least one braking module when the catch is at the second variant of the first operating position or at the second operating position; a holding device for holding the catch, when electrical power is on, at the first variant or the second variant of the first operating position, and for releasing the catch from the first variant or the second variant of the first operating position to the second operating position, when electrical power is interrupted, so that the at least one braking module performs braking operation by a biasing force received from the at least one force module or energy storage; at least one catching aid to transfer the catch from the second operating position to the first variant or the second variant of the first operating position; and the at least one braking device is configured to brake movement of the at least one lift car.
