Emergency measures
Emergency measures describe possibilities to move the elevator car in the
event of malfunctions or a failed drive for rescue measures or removal of
malfunctions.
Elevator car movement by releasing the shoe brakes
The fork-shaped end of the brake release lever with the two pins is to be
inserted in the drilled holes below the brake magnets. Illustration and
description, see Chapter 9 "Accessory parts"
Carefully pulling the end of the lever downwards opens the shoe brake. The
elevator car now moves downwards or upwards depending on the weight
distribution between the car and counterweight.
Note:
watch the speed of movement, as when overspeed is reached the
safety gear or emergency braking device is triggered.
After completion of the release operation, remove the release lever.
Elevator car movement by means of manual drive.
If the weight difference between the car and counterweight is too low, the
elevator does not move even if the brake is opened.
In this case, move the elevator car by means of the manual drive.
Note:
two persons
are required for elevator car movement with the manual
drive.
Remove the cover
plate
Remove the cover plate for the manual drive on the front of the drive.
Removing the cover plate means that the
limit switch
interrupts the power
supply to the drive motor.
With light turning movements, push the manual drive into the mounting
borehole
on the pedestal bearing and secure to the pedestal bearing with screws.
While one person releases the shoe brakes with the brake release lever, the
second person should move the elevator car by turning the handwinding
wheel. An illustration and description of the handwinding wheel can be found
in chapter 9 "Accessory parts".
