3.17 HOISTING AND LOWERING OPERATION
• With the boom deflection, the hoisted load slightly shifts forward. Notify the workers
around such as slinging operators.
• If the hook block is overhoisted, the overwinding prevention device detects overwinding
and the warning buzzer sounds intermittently. When the buzzer sounds, immediately
operate the right work equipment operation lever to the neutral position to stop the
hoisting operation.
• When lowering the hook for long distance for underground works, be sure to leave more
than 3 turns of the wire rope on the winch drum.
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 stopping the winch operation, do not suddenly
return the lever to the neutral position. Doing so may
loosen the wire rope, resulting in irregular winding of
the winch drum.
3.17.1 NORMAL HOISTING AND LOWERING OPERATION
Operate the right work equipment operation lever (1) as
follows.
• Lowering: Push the lever forward.
• Neutral: Release your hand from the lever.
The lever will return to the neutral position and the
raising/lowering of the hook block stops.
• Hoisting: Pull the lever toward you.
NOTES
Adjust the winch raising and lowering speed by the stroke of
the right work equipment operation lever (1) and the
depression amount of the accelerator pedal (2).
