Abstract

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.

Description

technical field [0001] The invention relates to the technical field of crane structures, in particular to an electric crane and a super-lifting electric crane. Background technique [0002] Mast cranes generally use moving pulley blocks to connect the luffing mast to the boom, and adjust the angle of the boom by changing the distance between the moving pulley blocks, so that the lifting radius and lifting height of the boom are changed to achieve luffing. The mobile mast crane generally also includes a lower body with a traveling device such as a crawler. [0003] In order to meet the needs of environmental protection and the use of clean energy, there are electric cranes in the prior art, and the power source of the hoisting device, the power source of the traveling device and the power source of rotation are all provided by batteries. [0004] However, the battery of the electric crane in the prior art occupies a large space and has a large weight, which leads to the prob...
