5. OPERATION
• Be sure to switch searcher hook according to the position of the actual machine. If you do not
perform position settings correctly, the moment limiter will not operate properly, and there is
a risk of serious injury through overturning.
• Do not use the searcher hook and the hook block of the crane main body at the same time.
While using the searcher hook, do not hang loads with the hook block of the crane main
body. And do not use with the hook block removed.
• When using the searcher hook, travelling operation cannot be performed. However, under the
specific conditions of no load, and when the boom is fully retracted, travelling operation does
become possible.
Normally, put the searcher hook in the stowage state for travelling operation, and switch the
searcher hook position of the moment limiter to “no display (stowage)”.
• For operational methods for the crane, see “Operation 3 Machine Operation and Control”.
1. As shown on the right, fully retract and lower the boom to
make it level and stop the engine.
2. Set the lock lever (1) to the Lock (L) position.
3. Fix bracket (1), plate L (2), plate R (3) to the tip of the main
boom using bolts, nuts and washers.
Tightening torque: 93 N·m ± 14 N·m
Then pass pin (4) through the holes of bracket (1), plate L (2),
plate R (3) as shown in the right figure, and tighten with bolts
to fix.
Tightening torque: 27 N·m ± 8 N·m
To prevent the searcher hook from falling, be sure to
tighten the searcher hook mounting bolts with the
specified torque.
When installing the searcher hook, be sure to use
Maeda genuine products and new bolts, nuts and
washers.
NOTES
Even when a bracket or plate is already attached, check
the tightening torque.
