9.4.5.15 Cable / hose drum
Attention!
Cleaning the cable / hose drum with steam stream or
high-pressure cleaner is not permissible!
Do not carry out boom movements without coverings of
the energy guiding chains at turret. If the cable / hose
drum does not roll up in case of a fault, the energy chain
can be damaged. If so, the boom movements will not be
interrupted. After maintenance works, screw again cov-
erings at turret in a correct way.

Check cable / hose drum for fastening, closeness and normal running
noises. In case of leakages or exceptional running noises, the cause
must be found out and the default must be eliminated.

Check elongation of electric lines and hydraulic hoses in the chain for
power track. If necessary, carry out maintenance works.

Check pretension of spring drive. If necessary, adjust.
Danger!
Risk of injury by opening the spring drive. The drive
is under high spring pressure. The spring drive may
only be opened by authorised personnel. Due to the
necessary know-how, we recommend letting the mainte-
nance and repair work carried out by the Ruthmann-after-
sales-service or by personnel authorized by us.

In case the chains for power track are constantly exposed to exceptional
surroundings (intense contamination), it is recommended to clean the
chains for power track in regular intervals adapted to the conditions.
