3.18 PROHIBITED OPERATIONS DURING CRANE WORK
• Always set the machine on level, solid ground when performing the crane operations. Check
the level state using a levelling instrument.
• Even when the crane must be unavoidably operated during travelling, be sure to stop the
machine once before operating it. Even if the right and left work equipment operation levers
are operated during travelling, this machine performs no operation other than the slewing
operation and boom retracting operation.
• Refer to the cautions given in “Safety” in addition to the prohibitions in this section.
DON’T OPERATE WITH SLEWING FORCE
Drawing in or lifting the load with slewing operation is prohibited.
DON’T OPERATE WITH DERRICKING FORCE
Drawing in or lifting the load with boom derricking operation is
prohibited.
DON’T PULL SIDEWARD, DRAW IN OR HOIST
DIAGONALLY
Pulling the load sidewards, drawing it in, or hoisting diagonally
applies unreasonable force on the machine. It not only
damages the machine body, but also is dangerous. Never
operate in this way.
The hook must lift right above the centre of gravity of the load
hoisted.
DON’T OPERATE VIOLENTLY DURING WORK
Do not operate the lever suddenly.
Especially, “slewing”, “boom lowering”, and “hook lowering”
must be operated at low speeds.
