ABSTRACT:
A control device includes an arm cylinder having a cylinder body and a piston that slides inside the cylinder body and a pump that supplies working oil to the arm cylinder, and decelerates the piston when it approaches a stroke end of the arm cylinder by adjusting a supply rate of the working oil supplied from the pump to the arm cylinder and a discharge rate of the working oil discharged from the arm cylinder. The position at which the piston starts decelerating is set further from the stroke end as the moving speed of the piston becomes higher.
