8.4.4 Motor brake
Check the braking distance
Carry out a test run with the hoist loaded and check whether the
motor brake overtravel in downwards travel is exceeded (trolley or
platform must not come to rest on the buffers).
Adjust the motor brake
The working air gap is measured in the braking position between the
anchor plate and the magnetic body. It increases due to wear. If the
wear of the brake pad is advanced to the point where the maximum
possible air gap of 0.5 mm is reached, the brake must be readjusted
because safe brake release can no longer be guaranteed. This is
evident by dwindling brake power or longer braking distance. The
minimum thickness of the pad is 6.5 mm, and the working air gap
should be set at 0.25 – 0.3 mm.
