6.5Emergency evacuation
Attention!
The measures for emergency evacuation described below may only be performed by instructed
persons for maintenance of the lift or quali
fi
ed personnel of lift companies.
6.5.1
Manual emergency evacuation
In case of power failure or failure of the recovery control, emergency rescue is only possible by
releasing the brakes manually. The picture shows how the levers must be actuated for hand release.
Manual lifting of the brake
The levers for hand release can be inserted with an offset of 90
°
in every position and can be actuated
±
25
°
on both sides.
possible insertion positions of the levers for hand release
When the brakes are released manually, the lift moves in the direction of the greater weight. If there is
a balance between the cabin and the counterweight, the cabin must be made heavier by suitable
means.
To reduce the acceleration of the lift, we recommend to short-circuit the motor for the evacuation. The
short-circuit is generated by the motor contactors.
The short-circuit generates a speed-dependent braking torque. The maximum braking torque is
achieved at lower speeds.
Depending on the system type and weight ratios, it is possible that due to the short-circuit
generated braking torque is not suf
fi
cient to limit the lift speed. So the speed must be
monitored closely during evacuation and evacuation interrupted if necessary.
Manual release of the brake is
fi
nished when a
fl
oor is reached. Now the lift door can be opened with
a triangular key.
The lift manufacturer's safety instructions have priority!
Danger!
The levers for hand release must be removed after brake hand release action.
A brake with a mechanical hand release system is available optionally. The hand release
system cannot be
fi
tted later. The complete brake must be replaced to retro
fi
t the hand release
system.
6.5.2
Electrical emergency evacuation
The electrical emergency evacuation is described in the operation instructions of the control, the
inverter and, if available, an evacuation unit with UPS.
