Lingong Group, a prestigious enterprise, has a history dating back to 1972, when it was just Shandong Linyi Construction Machinery Factory. However, after years of development, it has become one of the leading enterprises in China's construction machinery industry. As the chairman unit of China Construction Machinery Industry Association and the vice chairman unit of China Piling Machinery Association, Lingong Group not only enjoys a high reputation in China, but also emerges in the international market. 
Lingong Group's leading products include loaders, road rollers, excavators, motor graders, forklifts, cranes, road maintenance machinery, etc. These products are widely used in infrastructure construction, energy development, environmental protection and other fields, and have made important contributions to the country's economic development and improvement of people's livelihood.
