5.2 Boom bending and deformation
(1 mm = 3.93701 × 10
-2
in)
Item
Standard value (mm)
Remarks
Overall boom bending
(at full extension, maximum elevation angle, with
rated load)
IWY01-001001
No significant vertical or
horizontal bends shall be found
along the entire boom length.
Set the machine
level.
If necessary, adjust
the clearance
between the boom
and the slide plates
appropriately.

Check for deformation of side plates
There must be no large
deformation particularly on the
lower half surface of side plate
where pressure concentrates.
Check for twisting in the lengthwise direction when
boom is fully extended
