3.18 HOOK RAISING /LOWERING OPERATION
• With the boom deflection, the hoisted load slightly shifts forward. Notify the workers around
such as slinging operators.
• If the hook block was hoisted too much, the over hoisting will be detected. The alarm buzzer
sounds will be heard. When the alarm buzzer was heard, operate the right work equipment
control lever immediately to the NEUTRAL position and stop raising the hook.
• When lowering the hook for long distance for underground works, be sure to leave more than
three turns of the wire rope on the winch drum.
CAUTION
• Be careful not to over lower the hook block to avoid it
laying on the ground, which may result irregular winding
of the wire rope to the drum.
• During the winch operation, always avoid returning the
lever to the neutral position abruptly which loosens the
wire rope and may result in irregular winding of the wire
rope to the drum.
3.18.1 NORMAL HOOK RAISING/LOWERING OPERATION
Operate the right work equipment control lever (1) as follows.
• Lower: 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.
• Raise: Pull the lever toward you.
NOTES
Adjust the winch raising/lowering speed with the right work
equipment control lever (1) and stroke of the acceleration pedal
(2).
