6.2.8 BRUSHES OF THE MOTOR
The brushes of the motor are from carbon and they get wasted with
the use. To clean them, remove them from the motor one by one and
clean the excess of carbon dust on them. To clean the collector, use
compressed air while moving the crane slowly and the carbon inside
will be cleaned.
To have access to the brushes, loose the covers holding them into
the motor.
6.2.9 ELECTRONIC CONNECTORS
All the connectors are susceptible to get some moisture if the working environment is humid. To
clean them, disconnect the cable and spray some contact cleaner, let the contact cleaner dry before
connecting the crane again.
6.2.10 BELTS OF THE CRANE
There are 5 belts in the crane. It is explained how to tight them or replace in the following chapters:
The belts moving motors needs to be tight enough so there is no mechanical play between the gears
and the belt. The belts reading the encoders needs to be tight enough to do not skip teeth when
moving.
6.2.11 CABLE TROLLEYS
With the weight of the cables, the white wheels of the cable trolleys
get wasted and they can even touch the telescopic section when they
move causing noise. To tight them, remove the trolley from the crane
by extending it completely and removing the stopper at the end of the
rail and lose the 4 screws holding the wheels. Then use the guide
provided by Servicevision to press the wheels against the guide and
tight the screws. Mount it back in and verify that the tension of the
wheels is correct.
