5.2 - 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 telescope.
• Jib in horizontal position (if fitted).
From the magnetic comparator, note the clearance ( J1) between chassis (or turret) and the slew ring.
C l e a r a n c e b e t w e e n c h a s s i s ( o r t u r r e t ) a n d s l e w r i n g
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.
• Telescope the boom to its maximum angle (completely extend the telescope).
• 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 (0.08 in) : the test validates correct
operation.
• Otherwise, contact HAULOTTE Services® to repair the system.
