- Fig. 45-45a-45b show the lubricators of the inner and outer rams.
- Fig. 46-46a show the lubricators of the pin articulation column - inner boom
and inner boom - outer boom.
- Fig. 47 shows the lubricator of the multifunction return deviator.
When the hydraulic jib is fitted
- Fig. 48-48a
show the lubri-
cators of the articulation
pins for connecting boom
- jib outer boom and fork.
- Fig. 48b-48c
show the
lubricators of the jib outer
boom and of the fork.
For the sliding sections of
the extension booms of the
crane (fig. 49) and of the hydraulic jib (fig. 49b) and of the outrigger supports
(fig. 49a) guide shoes made from a special material have been fitted: to ease
their movement it is recommended to smear a light film of grease on them,
taking care that the surfaces of the extension booms are free from impurities
such as sand etc.
Use a grease with the same characteristics indicated in the table on page
37.
Check the tightening torque of the tie rods fixing the crane to the vehicle frame.
Check the tightening torque of the securing bolts for the ram pins.
Check the guide shoe wear as it affects the sliding section tolerances; if the
clearances are considerable, damage to the rams and the structure may
occur.
Replace the oil filter cartridges.
Clean the air filter placed in the top of the oil tank filter cap.
Completely replace the hydraulic oil.
(!) The waste oil must be disposed of by authorized persons.
