2.23 CRANE STOWAGE OPERATION
The hook stowage switch is used to cancel the automatic stop function of the over
winding detector.
Take sufficient care not to trap hands or objects when stowing the hook block.
CAUTION
• Before stowing the hook block, stop the hook block from swaying.
• When stowing the hook block, be careful not to allow the entire hook block to fall
sideways on the ground due to the wire rope being excessively loosened. Failure to
observe this may result in an irregular winding of the wire rope in the winch drum.
• The “Retract” operation of the boom will unwind the hook block. The “Lowering”
operation of the boom also causes the hook block to move downward. Wind the hook
at the same time so that the hook block will not touch the ground or interfere with the
machine.
• Be sure to stow the boom in the designated position. After the boom has been stowed,
make sure that the crane stowage lamp on the monitor is lit in yellow. If the crane
stowage lamp is not lit in yellow, the outriggers cannot be stowed. If the crane
stowage lamp is not lit, perform operations, such as lowering the boom to its lowest
position, or slewing the boom, and check if the crane stowage lamp lights up in yellow.
[Manual stowage]
1. Pull the left control lever (2) toward you to retract the
boom completely.
2. Push and hold the left control lever (2) to the left or right
to slew the boom so that the slewing angle becomes 1
to 2 degrees.
If the boom angle is less than 12 degrees, the boom
cannot be slewed between 335 to 3 degrees to
prevent work directly above the operator.
3. Push and hold the right control lever (1) to the right until
the boom stops automatically.
