The present invention relates to an electric crane which is operated in a driving motor (121) method, and more specifically, to an electric crane which does not cause interference in operation due to an electric cable (C) supplying electricity to the driving motor (121). To this end, the electric crane of the present invention comprises: a lower driving body (120); a driving motor (121) installed at one side of the lower driving body (120); a cable roller (140) installed at the lower driving body (120), around which the electric cable (C) supplying electricity to the driving motor (121) is wound; a trolley (200) connected to a rear side of the lower driving body (120) by means of a rotating connection unit (300); and a cable mounting rack (210) installed at the trolley (200) in order to lift the electric cable (C) extended from the cable roller (140) such that the same may not come in contact with the floor of a worksite.

    본 발명은 구동모터(121) 방식으로 구동되는 전기식 크레인에 관한 것으로서, 보다 상세하게는 구동모터(121)에 전력을 공급하는 전기케이블(C)로 인한 운행 지장이 발생되지 않는 전기식 크레인에 관한 것이다. 본 발명의 전기식 크레인은 하부주행체(120)와, 상기 하부주행체(120) 일측에 설치되는 구동모터(121)와, 상기 하부주행체(120)에 설치되며, 상기 구동모터(121)에 전력을 공급하는 전기케이블(C)이 감겨진 케이블롤러(140)와, 회동연결유닛(300)을 통해 상기 하부주행체(120)의 후방에 연결된 대차(200)와, 상기 대차(200)에 설치되어, 상기 케이블롤러(140)로부터 전개되는 전기케이블(C)이 작업장 바닥과 접촉되지 않도록 리프팅시키는 케이블 거치대(210)포함한다.
