Abstract
An excavator attachment is attached to an excavator rotating platform. During normal operation, a drive means drives the attachment according to operator input into a manipulation device. A sensor detects motion of the excavator. Based on output of the sensor, a slip suppression unit detects slipping of the excavator undercarriage in an extension direction of the attachment, and corrects operation of the attachment performed by the drive means.
