(Chapter 3) - ROUTINE MAINTENANCE
On the crane basement there
is a number of grease nipples
(zerks) that has to be used to
grease the 3 poin linkage pin,
the slew bearing (internal
ring), the outriggers and the
pinion (picture 30).
3.1 - AFTER THE FIRST 20 HOURS OF OPERATION
•
Grease all the parts identified with the diagram in picture 31.
•
Kleen or replace the flter on the pressare line.
3.2 - AFTER THE FIRST 300 HOURS OF OPERATION
•
Check the torque of the tie rods securing the base to the chassis, using a torque
wrench
(torque: 67 daN*m(lubricated) – 72.9 daN*m (not lubricated)).
•
Check the torque of the bolts securing the thrust bearing to the crane base and
eventually tighten with a torque wrench.
(torque: 67 daN*m(lubricated) – 72.9 daN*m (not lubricated)).
•
Verify the tightening torque of the bolts holding the gearbox on the plate with a
torque spanner
(torque : 22 daN*m).
•
Verify the tightening of the bolts that hold the brake on the gearbox (torque 2.6
daN*m) and between rotation motor and brake (torque: 5 daN*m).
3.3 - PERIODIC MAINTENANCE
3.3.1 - EVERY 20 HOURS OF OPERATION
•
Verify the oil level inside the hydraulic-oil tank: the level must be on the same line
of the level indicator, when crane is folded and outriggers retracted. (picture 31).
