With the development of national economy and the progress of science and technology, China’s construction machinery has made great progress. At present, China’s hydraulic excavators, tire loaders, truck cranes have formed a series of products. Crawler dozers, tire cranes, self-propelled scrapers, graders and vibratory rollers all form the basis of mass production. In recent years, with the rise of urban construction industry, the rapid development of highway construction and port construction requires that not only the quality but also the quantity of construction machinery should have a great development. Especially the majority of rural civil construction and small and medium civil engineering construction, there is an urgent need for rural areas
