[0002] The casting electric furnace utilizes a medium-frequency induction furnace on the equipment used in the original foundry industry. Casting is the process of melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification, and cleaning, a casting with a predetermined shape, size, and performance is obtained. The casting electric furnace requires a balance crane when loading materials. A balance crane is a material lifting equipment. Balance cranes are mainly used in factory workshops, docks, warehouses, and other places that require high-frequency, short-distance lifting operations.

[0003] In the prior art, Chinese patent publication number CN219341531U discloses a mobile hydraulic balancing crane, which relates to the technical field of balancing cranes. The utility model includes a hydraulic balancing crane body and a mobile base. A counterweight is provided at one end of the hydraulic balancing crane body, and an electronic crane scale is provided at the other end of the hydraulic balancing crane body. A mobile base is fixed to the bottom side of the hydraulic balancing crane body, a counterweight box is fixed to one end of the upper side of the mobile base, and a hydraulic cylinder is clamped around the upper side of the mobile base. The utility model solves the problem that a large amount of heavy objects need to be placed on the upper side of the base of the mobile hydraulic balancing crane to improve the stability of use during actual operation through the hydraulic balancing crane body and the mobile base, but this will greatly increase the labor intensity of the staff, and the counterweight of the hydraulic balancing crane is inconvenient to replace, and it is difficult to quickly determine whether the counterweight needs to be replaced.

[0004] However, in actual use, when replacing the counterweight, it is difficult to carry and lift the counterweight because the counterweight has a certain weight. The balance arm has a certain height, and the counterweight needs to be lifted to correspond to the installation position of the balance arm during installation, which is labor-intensive and difficult to replace. Therefore, improvement is needed. Utility Model Content
