In some civil engineering such as underwater construction, or long ditch digging for underground pipelines, the digging operation is quite difficult because the operator cannot easily set a guide line for digging reference. This paper describes the development of a hydraulic excavator equipped with an electrical lever system. The excavator is equipped with a limited plane digging control system and a multi-monitoring display. With the assistance of the system, the operator can pre-set a desired working plane through the monitor screen. Then the digging control system will automatically control the actuators so that the bucket will not go below the plane. The plane can be horizontal, or in any angle to the horizontal. During the operation, the monitor will display the digging state in realtime.
