3.17.2 CRANE STOWAGE OPERATION AT THE TIME OF NORMAL STOWAGE OF
HOOK BLOCK
• When stowing the hook block, carefully (at low speed without full stroke) operate the right
and left work equipment operation levers. Otherwise, the hook block may sway considerably,
not only damaging the peripheral equipment but also causing serious physical injury.
• Raise the boom to near the hook block stowage position. If the hook block is away from the
stowage position, the hook block may come off, not only damaging the peripheral equipment
but also causing serious physical injury, when the hook block is going to be hung on the
rope for stowage.
CAUTION
• Prior to normal hook block stowage, stop the hook block from swaying.
• 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 “Lowering” operation of the
boom also causes the hook block to move downward. Perform the hoisting operation
simultaneously so that the hook block does not fall sideways on the ground.
1. Operate the left work equipment operation lever (2) to
the “Retract” side (pull toward you) to retract the boom
fully.
NOTES
The hook block lowers with the boom retracting operation.
Perform the hoisting operation as appropriate and hoist
the hook block.
2. Operate the right work equipment operation lever (3)
to the “Raise” side (pull inside) and raise the boom up
to the position where the hook block nears the normal
stowage position.
