5 - Criteria of replacement
Check the slewing system every 500 h or each major intervention done on the machine.
Step 1 : Visual and sound check :
Replace slew ring in the following cases :
• Abnormal noise during the turntable rotation.
• Movement jolts during the rotation of the turret.
• Gear teeth missing or damaged.
• Presence of metal particles in the grease.
• Wear on gear teeth.
Step 2 : Measurement of the clearance :
Place the machine in the following conditions :
• On flat ground, Set up barriers to define the test area.
• No load in the platform.
• From the ground control box, align the turret at 90 ° to the chassis.
• Lift the boom approximatively 30 ° from the ground.
• Completely retract the boom.
• Jib in horizontal position(if fitted).
From the magnetic comparator, note the clearance ( J1) between chassis (or turret) and the slew ring.
Clearance between chassis (or turret) and slew ring
After having carried out the measurement :
• Lower the boom at horizontal position.
• Lift the arm (if exists) as its maximum position. Don’t extend the telescopic boom.
• The telescopic boom should be fully extended and in the horizontal position..
• Jib in horizontal position(if fitted).
In its new configuration, note the clearance ( J1) between chassis (or turret) and the slew ring as
previously.
• If the difference between two measurements does not exceed 2 mm : the test validates correct operation.
• Otherwise, contact HAULOTTE Services® to repair the system.
