METHOD FOR MOVING AN ELEVATOR CAR OF AN ELEVATOR FOR THE EVACUATION OF PASSENGERS AND BRAKE OPENING DEVICE FOR MOVING AN ELEVATOR CAR OF AN ELEVATOR

摘要

The invention concerns a procedure for moving an elevator cab to evacuate passengers from the elevator cab in the event of a power failure. In the event of a power failure, a brake blocks the lift cab's height movement. The ConstitutionEars include the following steps: transfer an electrical power to the elevator brake to release the brake and release the height movement of the lift cab. The brake is in a variety of positions depending on the transmitted electrical powerwhich are movable and durable between a fully closed position and a fully opened position. Determine the actual speed at which the lift cab moves. Compare the actual speed with a target speed. Adjust, in particular increase or decrease the electrical power transferred to the brake depending on a deviation of the actual speed from the target speed, so that the actual speed corresponds essentially to the target speed.
