CRANE OPERATION
Dos and Don’ts During Crane
Operations
WARNING!
• Always set the outriggers on the levelled
solid ground when performing the crane
operations.
• Never perform Pick & Carry or the crane
operations without setting the outriggers.
The machine will be unstable and overturn,
leading to serious accidents.
• See the cautions given in "Section 2
SAFETY" besides the dos and don’ts in this
section.
Do Not Operate with Slewing Force
Drawing in or lifting the load with slewing
operation is prohibited.

Do Not Operate with Derricking Force
Drawing in or lifting the load with boom derricking
operation is prohibited.

Do Not Pull Sideward, Draw in, and
Hoist Diagonally
Pulling sideward, drawing in, or hoisting
diagonally applies unreasonable force on the
machine. It not only damages the machine body,
but also is dangerous. Never operate in these
ways.
The hook must come right above the centre of
gravity of the load hoisted.
Fig. 4-149
Do Not Operate Violently
Do not operate the lever suddenly.
Especially, the "slewing", "boom lowering", and
"hook lowering" must be operated at low speed.

Do Not Access into Working Radius

such as permitting an operator to go under the
hoisted load.
