Problems solved by technology

[0004] With the development of the global economy and trade, the large-scale bridge-type cranes have made the transportation of the whole machine more and more important. Factors); ②The risk of the whole machine transport by sea (with the large-scale of shore container cranes, the whole machine is getting heavier and higher, and its height is getting higher and higher, which brings more and more risks of the whole machine transportation); ③ The limitation of factors such as the municipal construction conditions of the city where the factory and the user's wharf are located, as well as the high transportation and bundling costs also restrict and tie up the manufacturer
