3.22 CRANE STOWAGE OPERATION
3.22.1 CRANE STOWAGE OPERATION AT THE TIME OF SIMPLE STOWAGE OF
HOOK BLOCK
• The hook storage switch cancels the automatic stop function of the overwinding
prevention device.
When storing the hook block, carefully operate the right work equipment operation lever
and pay due attention not to allow the hook block to crash against the stowage position
at the boom tip.
• Move by storing the hook block in the simple stowage position only when moving inside
the worksite a short distance between crane operations. When moving a long distance
such as when moving to the worksite or going to and from the transportation place, store
the hook block in the normal stowage position in the front of the revolving super structure.
• When storing the hook, be sure to make the boom is level before performing the stowage
operation. If the hook is stored with the boom raised up, the rubber on the upper part of
the hook block can be broken.
• Do not raise or lower the boom with the hook stored. The rubber on the upper part of the
hook block can be broken.
• Do not turn the override switch to the "ON" position when performing the hook stowage
operation. Doing so does not bring the mode into the hook stowage mode, and the rubber,
boom and wire rope on the upper part of the hook block may be broken.
CAUTION
• Stop the sway of the hook block before storing the
hook block in the simple stowage position.
• 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.
•
The boom “Retracting” operation will lower the hook
block.
The hook block also lowers with the boom
“Lowering” operation. Perform the hoisting operation
simultaneously so that the hook block does not fall
sideways on the ground.
•
Perform the hoisting operation slowly and do not
perform the hook block stowage operation with high-
speed hoisting of the winch.
