The invention provides an electric crane and a super-electric crane, and relates to the technical field of crane structures. The electric crane and the super-electric crane are designed to solve the problems that in the prior art, a battery of an electric crane is large in occupied space and large in weight, and consequently the electric crane is heavy and large in occupied area. The electric crane comprises an upper crane body, a lower crane body, an arm frame, an amplitude variation mast, a center weight box, a rear weight box and a battery pack. The upper crane body is rotationally erectedabove the lower crane body. The arm frame, the amplitude variation mast and the rear weight box are sequentially arranged on the upper crane body. The center weight box is arranged on the lower cranebody. The battery pack is arranged on the center weight box and/or the rear weight box and used for providing electric power of work for the electric crane.

    本发明提供一种电动起重机及超起电动起重机,涉及起重机结构技术领域,为解决现有技术中存在的电动起重机的电池占用空间较大、且重量较大,导致电动起重机笨重且占地体积较大的问题而设计。本发明提供的电动起重机,包括上车体、下车体、臂架、变幅桅杆、中央配重箱、后配重箱以及电池组。上车体转动架设于下车体上方,臂架、变幅桅杆以及后配重箱依次设置于上车体;中央配重箱设置于下车体。电池组设置于中央配重箱,和/或后配重箱,电池组用于提供电动起重机工作电力。
