ABSTRACT:
In controlling a hydraulic excavator equipped with a front mechanism having multiple foldable and rotatable joints, the controlling method described enables complex joint actions to be controlled readily by manipulating electrical joy sticks. Translational and rotational control commands are input to a certain point on the longitudinal axis of a rear arm through the joy sticks and cooperative actions of multiple joints are achieved simultaneously.
