The present invention relates to an electric excavator also used as an engine, which is able to a diesel engine and an electric motor mounted, and allow a worker to work by operating the diesel engine for long distances and operating the electric motor in a workshop, comprising: an operation mode conversion unit which makes the operation conducted by converting between the electric motor and the diesel engine; a cable whose one end is connected to a power supply unit and whose other end is connected to the electric motor; a reel on which the cable is wound, and which releases the cable when the excavator moves away from the power supply unit and which automatically winds the cable when the excavator moves closer to the power supply unit; a detection unit including a distance detection unit for detecting the moving distance of the cable; a control unit which receives a signal of the distance detection unit, calculates a residual length of the cable moving along with the excavator as well as the pre-saved total length of the cable, and warns if the residual length is shorter than a preset reference residual length; and a vision display unit which displays the residual length calculated by the control unit, and outputs a warning message when the residual length is shorter than the preset reference residual length.

    본 발명은 디젤엔진과 전기모터를 장착하고, 원거리 주행은 디젤엔진을 동작시키고, 작업장에서는 전기모터를 가동시키며 작업을 할 수 있도록 하는 전기굴삭기로써, 전기모터에서 디젤엔진, 디젤엔진에서 전기모터로 전환시켜 동작이 이루어지록 하는 동작모드 전환부; 일단은 전원공급부와 연결되고 타단은 상기 전기모터와 연결되는 케이블; 상기 케이블이 감아지며, 굴삭기가 전원공급부에서 멀어지면 케이블이 풀리고, 가까워지면 자동으로 케이블 감는 릴; 케이블의 이동 거리를 검출하는 거리검출부를 포함하는 감지부; 상기 거리 검출부의 신호를 수신하고, 기 입력된 케이블의 전체 길이와 굴삭기의 이동과 함께 이동하는 케이블의 잔여 길이를 산출하고, 잔여길이가 기설정된 기준 잔여길이보다 짧으면 이를 경고하는 제어부; 상기 제어부에서 산출된 잔여 길이를 표시하고, 릴에 잔여하는 잔여 길이가 기설정된 기준 잔여길이보다 짧으면 경고 메세지를 출력하는 시각표시부;로 구성된 기술적인 특징을 갖는 것으로 달성된다.
