Never perform a swinging operation suddenly while suspending a load. Doing so may cause the suspended load to be pulled with a centrifugal force, causing the machine to roll over.Never suddenly swing, and stop or lower the hook suddenly, as doing so may cause the wire rope to come off the hook latch.
Factors that cause the wire rope to come off
Illustration 7 g02963717 (1) Wire rope in normal condition. (2) The wire rope gets raised when the hook is lowered too suddenly. (3) If the wire rope gets twisted and gets untwisted in the direction of the arrow, the wire rope will go beyond the tip of the hook. (4) The wire rope goes around the back of the hook. (5) The hook goes up or the wire rope goes down. (6) The wire rope simply falls off.Diagonal dragging operation is prohibited.
Illustration 8 g02963718
Diagonal dragging operation applies an abnormal force on the hook and may cause the hook to break, resulting in serious injuries or death. Never perform such an operation.
Leaving the seat while suspending a load is prohibited.
Illustration 9 g02963720Do not leave the operator seat while a load is being suspended. The load may fall, resulting in personal injuries. Do not allow a slinging operator or another worker under the load.Temporarily stopping the lifting operation.
Illustration 10 g03229439When there is a large area to stop the machine, fully retract the stick cylinder and slowly lower the boom until the bucket contacts the ground.Note: Make sure that the lifting tool does not get caught under the bucket.
Illustration 11 g03229456When there is small area to stop the machine, press the shovel crane button on the switch panel in order to disable the operation. Position the stick so that it is perpendicular to the ground and slowly lower the boom until the bucket contacts the ground.Note: Make sure that the lifting tool does not get caught under the bucket.Store the hook during a bucket operation.

Be sure to store the hook during a bucket operation. Otherwise, the bucket, the hook, and other parts may become damaged.Wire rope suspension angle
Illustration 15 g02963723As a rule, try to set the wire rope suspension angle at 60° or below.Keep out of the area under a suspended load.
Illustration 16 g02963725Never allow anyone to enter an area under a suspended load.Lifting operation with a quick coupler device is prohibited.
Illustration 17 g03289716
(7) Quick CouplerAccurate lifting load and operation range cannot be displayed in a lifting operation equipped with a quick coupler. Furthermore, never perform a lifting operation with a quick coupler attached, as doing so causes the hook to contact the quick coupler, applies an abnormal force on the hook, and causes the hook to become damaged and/or the machine to roll over.
