2.25 PROHIBITED OPERATIONS DURING CRANE WORK
• Always set the outriggers on level, solid ground when performing the crane
operations.
• Never perform travelling hoist or crane operations without setting the outriggers.
The machine will be unstable and overturn, leading to serious accidents.
• See the cautions given in the “Safety” besides the do’s and don'ts in this section.
[1] DON'T OPERATE WITH SLEWING FORCE
Drawing in or lifting the load with slewing operation is
prohibited.
[2] DON'T OPERATE WITH DERRICKING FORCE
Drawing in or lifting the load with boom derricking
operation is prohibited.
[3] DON'T PULL SIDEWARD, DRAW IN OR HOIST DIAGONALLY
Pulling the load sideways, 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 center of gravity of the
load hoisted.
[4] DON'T OPERATE VIOLENTLY DURING WORK
Do not operate the lever suddenly.
Especially, “slewing”, “boom lowering”, and “unwinding”
must be operated at low speeds.
