Assembly Adjustment (Crane Operation)
4.2 Upper and lower bubble level adjustment
After leveling the slewing table plane, adjust so that the bubble in each upper and lower bubble level is
center-aligned to the mark using the adjuster screw of each bubble level with the boom directed to over-front
and boom angle of 50°.
4.3 Adjustment check
Finally check if the "Inspection standard of bubble levels' bubble position" is satisfied.
Conditions: Outriggers at full extension; boom fully retracted and no load on the hook block.
• Standard for the upper bubble level: Slew the boom with the boom angle of 50°.
Check that the bubbles are within the marked range when the boom
is directed to front, rear, right and left.
• Standard for the lower bubble level: While the boom is directed to over-front and stowed, check that each
bubble is within the marked range.
4.4 Readjustment
If the standard is not satisfied, check whether the jacks are shaky and make adjustment again.
