Rules for Operation
(Special Operation)
Be Cautious in Multi-Crane Operation
Lifting a load with two or more cranes can be dan-
gerous. In these operations, loads are lifted at
points other than directly above the center of gravity
and there is possibility of the load falling, the ma-
chine being overturned, or the boom failing.
In multi-crane lifting operations, be absolutely care-
ful, and adhere to the following instructions:
• Meet with personnel to determine the proper
working procedure and lift strategy.
• Assign a work leader, and follow instructions.
• Equip every person concerned with an appropri-
ate communications device.
• Set each crane level on firm ground with the out-
riggers fully extended.
• The cranes used must have the same perfor-
mance, characteristics and sufficient capacity for
handling the load. Make sure that the cranes have
the same settings for the boom length, boom an-
gle, and number of rope parts.
• Lift the load so that the wire rope(s) of each crane
are only subjected to vertical line pulls.
• Attempt to rig the load so that all the cranes are
loaded equally.
• To move the load, use only the winches and
booms. Swinging operations should be avoided.
Do not perform hoisting, elevating (or telescop-
ing) of the boom or swinging at the same time.
• To prevent overloading, operate the separate
cranes simultaneously.
After Operation
After Operation, Stow the Machine
Leaving the machine unattended should be avoided.
Once operation is complete, stow the machine.
Cautions for Refilling the Fuel
Fuel and other oils are highly flammable and dan-
gerous.
Handle combustibles very carefully.
While refueling, observe the following instructions:
• Stop the engine.
• Refuel the machine outdoors in a well-ventilated
place.
• Keep sources of flames or sparks away from the
fuel.
• Wear a protective mask.
• Do not refuel in excess of fuel tank capacity.
