The use of double-girder cranes has huge market demand and good economy. In recent years, the double-girder crane manufacturing industry has developed rapidly, with an average annual growth rate of about 20%. Because in the production process from raw materials to products, the handling capacity of materials by double-girder cranes is often dozens or even hundreds of times the weight of the product. According to statistics, for every 1 ton of products produced in the machining industry, 50 tons of materials must be loaded, unloaded, and transported during the processing process, and 80 tons of materials must be handled during the casting process. In the metallurgical industry, for every ton of steel smelted, 9 tons of raw materials need to be transported, the transfer volume between workshops is 63 tons, and the transfer volume within the workshop reaches 160 tons. Lifting and transportation costs also occupy a high proportion in traditional industries. For example, the cost of lifting and transporting in the machinery manufacturing industry accounts for 15-30% of the total production cost, and the cost of lifting and transporting in the metallurgical industry accounts for 35% of the total production cost. ～45%, the loading, unloading and storage of goods in the transportation industry depends on lifting and transporting machinery.
