[4] INSPECTION/ADJUSTMENT OF BOOM TELESCOPING WIRE ROPE
[INSPECTION OF 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) (4 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.5 boom is extended when the adjusting bolt (9)
is turned.
If the No.5 boom is not extended, refer to the section,
“Adjustment of Wire Rope” and adjust it.
4. Check for a 5 mm or more gap between booms No.4 and
5 when the booms are fully retracted in a horizontal
position.
If there is a clearance of 5 mm or more, perform proper
adjustment according to “Adjustment of Wire Rope”.
