Cranes are one of the most widely used equipment in power plants, nuclear power stations, docks, water conservancy, tunnels, bridges, petrochemicals, metallurgy, and construction industries. In the latest "Eleventh Five-Year" plan, investment in various construction industries has maintained a steady upward trend. Water conservancy, hydropower, energy, and mine construction have new project plans, flood control projects, “three rural” water sources, eight major hydropower project projects, and an additional investment of more than 430 billion yuan in the West-to-East electricity project to start natural gas development and transportation projects. All of these give the crane new opportunities for development. In 2006, in the face of China's power shortage, according to the State Grid Corporation of China and China Southern Power Grid's “Eleventh Five-Year” power grid development plan, the total investment in China’s power grid construction will exceed RMB 1 trillion in the next five years. During this period, power grid construction investment Will account for more than 50% of the total investment in the power industry, can basically meet the new power transmission and distribution needs. With the large demand for cranes from these large-scale projects, the domestic crane market has accelerated its development.
