5.3.1 Motor Brake
In order to achieve sufficient braking torque
for the brake, it is important, that the brake
clearance is correctly adjusted and that
the brake disc cover is in perfect condition.
If the air slot is too big adjust the brake. In
case the air slot is too big the brake does
not stop the hoist properly and as a result
the braking distance becomes long or in
the worst case the brake does not work at
all.
The nominal brake air slot is 0,4 mm. The
brake must be adjusted if the air slot ex-
ceeds 1,1mm
The brake is adjusted as follows:
-
Unscrew the fastening screws.
-
Adjust the adjusting screws, every
one of them evenly.
-
Tighten the fastening screws.
-
Measure the air slot with a clearance
gauge
The friction disc must be replaced, when
it its thicker than 10 mm, which is the mini-
mum permissible thickness for a friction disc
The friction disk is adjusted as follows:
-
Unscrew the fastening screws.
-
Pull the brake backwards and re-
place the friction disc.
-
Fasten the brake with the fastening
screws.
-
Adjust the air slot as described
above.
During the inspection clean the brake
from braking dust. If there is a sealing tape
around the brake remove it and blow the
dust away. Use a breathing mask when
cleaning the brakes.
Lower the cage to ground
station and lower manually
on the buffer springs before
brake service

ing and mainteance instruc-
