the lifting equipment.
5.3.2.4 -Steering crown wheel
The periodic inspection of the condition of the steering crown wheel is
essential to ensure safe use and the machine's lifespan..
The service operation of a machine
with a crown wheel which is badly
maintained or in bad condition
creates dangerous operating
conditions which can cause serious
or fatal injury and damage to
components.
Greasing:
• Grease the teeth of the crown wheel using a paintbrush, while visually
checking the wear on the teeth.
• Grease the travel path using the 2 greasers accessible through the
holes in the turret until the grease comes out of the crown wheel lip
seal. Carry out complete rotations of the crown wheel before and after
greasing. Any hard point or squeaking during the rotation, or metallic
particles in the drained grease are signs of abnormal use of the travel
path: contact Haulotte service.
The tasks below must be carried out by trained competent personnel:
contact Haulotte Services..
Tightening screws:
• Tightening torque: check the values given in Table 5.3.1, “Summary
table”, page 42.
Checking play :
• Gear teeth play: Check that the play between teeth meets the values
given in Table 5.3.1, “Summary table”, page 42.
• Travel path play: Check that the play meets the values given in
Table 5.3.1, “Summary table”, page 42.
5.3.2.5 -Static checks of the jacks
The periodic inspection of the condition of the jacks is essential to ensure
safe use and the machine's lifespan.
After carrying out any work on any part of the hydraulic circuit of the
machine, a static test should always be carried out before returning the
machine into service. The tasks below must be carried out by trained
competent personnel: contact Haulotte Services.
The service operation of a machine
with one or more jacks in bad
condition creates dangerous
operating conditions which can
cause serious or fatal injury and
damage to components.
NOTE : Periodic testing of the jacks is a regulatory requirement in cer-
tain countries.
Before starting the static tests, check that the hydraulic circuit is correctly
purged (run several cycles for each movement) and that the jacking of the
connecting piece is correct (chap. 4.4.1.3, page 32). All of the operations
below must be carried out on flat ground, in an open area, with a 290 kg
load in the platform (1, 25x of the nominal permitted load).
