3.11 OPERATION BEFORE CRANE WORK
If the boom extending and raising operations are performed with the hook block hung on the
wire rope for stowage, the wire rope for stowage is broken and the vicinity of the normal
stowage device in the front of the revolving super structure is damaged. Be sure to perform the
hook lowering operation so that the wire rope for stowage is not tightened.
CAUTION
• Be careful not to lower the hook block excessively
so that the hook block does not fall sideways on the
ground. Doing so results in irregular winding of the
winch drum.
• When the hook block is loosened from the normal
stowage position, the hook block may sway,
interfering with and damaging the peripheral
equipment. Pay thorough attention around the hook
block.
Perform the following operations before crane work.
1. Place the lock lever (1) at the Free position (F).
2. The accelerator pedal (2) should remain at low idling.
3. Operate the right work equipment operation lever (3) to
the “LOWER” side (push forward) to lower the hook block
(4) and loosen the rope for stowage (5) (normal stowage
position).
NOTES
At this time, do not lower the hook block (4) excessively.
If it is excessively lowered, the loosened hook block (4)
may damage the peripheral equipment.
