6.6. Emergency evacuation
Manually operated evacuation in case of emergency
• The brakes can be opened manually by using the lifting levers (option)
• Two different options can be chosen (shown in the following pictures):
Danger
All actions for evacuation in case of emergency have to be done by qualified service
personnel.
Warning
When the evacuation is finished, the initial state has to be restored. Especially the
lever extensions have to be removed.
Manual lifting rods (machine room):
Brake manual release remotelly controlled:
• Is the brake opened manually, the cabin moves in the direction of the higher weight. In case of balance, the
cabin has to be weighted down with suitable additional mass.
• The motor winding has to be short-circuited via the motor contactors. With the short circuit the motor cre -
ates a brake torque, which is dependent on the motor speed. This prevents an uncontrolled acceleration of the
elevator.
• It is possible that the brake torque which is created by the motor short circuit is not enough to limit the
speed of the elevator. Therefore the cabin speed has to be observed carefully during the evacuation and if
needed, the evacuation has to be stopped.
• When the cabin has reached the next floor, the manually opened brake is closed again. The rescue of the
trapped persons in the cabin can begin.
Electrically operated evacuation in case of emergency
• The electrical opening of the brakes is done using the power grid or an UPS.
• The operating instructions of the controller, the inverter or the evacuation unit with UPS have to be fol lowed!
