摘要
The overloaded bucket is automatically controlled so as to move in a desired distance in a direction opposite to the excavating direction and then move up to a height in order to be free from the overloaded state. The operator handles the control levers/pedals so that the bucket free from the overloaded state continuously carries out its desired excavating operation. An automatic actuating system for actuators of the excavator provides an advantage in that it allows even an unskilled operator to easily operate the actuators even when an overload occurs on the bucket during an excavating operation.
