(4) Use each winch lever to hoist or lower.
When you return each winch lever to neutral, the automatic brake device automatically applies the brake.
(5) Drum rotation detector switch
The rotation of the winch drum which is selected by this switch is
detected during winch operation and a buzzer will sound to
indicate that the winch drum is rotating.
NOTE
The buzzer sound is the same for hoisting and lowering.
NOTE
The buzzer sound becomes faster the faster the drum rotates.
When the drum speeds up f urther, the buzzer sounds
continuously and then dies away.
・
When the wire rope number of parts does not correspond to the boom length, the hook will
not reach the ground and the winch drum can wind up the wire rope in reverse, which can
cause the wire rope to be damaged or the crane to tip over.
・
When hoisting from below the ground or working with a long boom, refer to the table for wire
rope standard number of parts and use the adequate number of parts for the boom length with
which you are working.
