METHOD FOR MOVING AN ELEVATOR CAR OF AN ELEVATOR FOR EVACUATING PASSENGERS, AND BRAKE OPENING DEVICE FOR MOVING AN ELEVATOR CAR OF AN ELEVATOR FOR EVACUATING PASSENGERS

摘要

The invention relates to a method for moving an elevator car (10) of an elevator (5) for evacuating passengers from the elevator car (10) of the elevator (5) in the event of a power outage, in which a brake (18) blocks a vertical movement of the elevator car (10). The method comprises the following steps: Applying an electrical pulse, or a plurality of electrical pulses, to the brake (18) of the elevator car (10) for releasing the brake (18) and unblocking the vertical movement of the elevator car (10), wherein the brake (18) is released as long as the relevant electrical pulse is applied to the brake (18); determining a travelled height that the elevator car (10) has travelled while the relevant electrical pulse was applied; comparing the determined travelled height with a specified distance (d_max); and stopping the application of the relevant electrical pulse to the brake (18) when the determined travelled height equals the specified distance (d_max) or is greater than the specified distance (d_max).
