INSPECTION/ADJUSTMENT OF THE BOOM TELESCOPING WIRE ROPE
When the boom extending wire rope shows a condition as
shown in the figure below, adjust as follows:
1. Make sure the boom is fully retracted.
2. Remove the mounting bolts (1) (3 bolts) on the boom tip
and then remove the cover (2).
3. Remove the lock bolt (6) on the tip of extension cylinder
inside the boom and turn the boom extending wire
adjusting bolt (9) clockwise.
The tension of the boom extending wire (8) is normal, if
the No. 4 boom is extended when the adjusting bolt (9)
is turned.
If the No. 4 boom is not extended, refer to the section,
“Inspection and Maintenance 10.3 Irregular
Maintenance (Adjustment of Boom Telescoping Wire
Rope)” and adjust it.
4. Check for a 5 mm or more clearance between booms
No. 3 and No. 4 (clearance (a) on the diagram on the
right) when the booms are fully retracted in a horizontal
position.
If there is a clearance of 5 mm or more, refer to section
“Inspection and Maintenance 10.3 Irregular
Maintenance (Adjustment of Boom Telescoping Wire
Rope)”, and adjust it.
