Inspection before starting crane operation
★
Be sure to carry out inspection of turn over prevention device before
starting the crane operation to check that the device functions normally.
If found something wrong with the device, ask a UNIC authorized ser-
vice shop for repair as soon as possible.
★
Turn “ON” the turn over prevention alarm buzzer switch while carrying
out preparation of the crane operation to check that continuous
alarm sound is heard until the outriggers are set up on the ground.
If the alarm fails to sound, ask a UNIC authorized service shop for
repair immediately as something is wrong with the turn over prevention
device.
★
The crane might be overturned even if the system has been actu-
ated when a lifted cargo is swinging and/or operation speed is too fast
because the load is increased by inertia.
Do not rely too much on the system but try always carrying out safe
operation of the crane carefully by observing that the load is kept within
the rated load.
