Suspension is a bulldozer blade with self-propelled earth-moving machinery

Bulldozer is Crawler Earthmover  or tractor tire tractors special chassis as the host, together with the suspension blade (with The device comes with a ripper) self-propelled earth-moving machinery. Bulldozer at work, the shovel knife buried in, rely on forward travel drive system provides power to complete the cutting, pushing soil work, sometimes used as a filling, flat, tillage work. Hydrostatic driven earthmover  used to lift heavy physical labor, accelerate the construction schedule, to ensure construction quality. So it is a widely used in construction, road building, mining, agriculture, forestry, construction and other areas of basic national defense construction machinery.

Currently, hydrostatic drive and control technology in vehicle systems has been widely used and considerable progress, particularly with low-speed track job means moving vehicles. But in the bulldozers, earth-moving machinery in the application of domestic premature. With the development of China's highway construction, the number of construction projects for construction machinery has increased significantly, and the quality have higher requirements. Bulldozer plays an important role in construction projects, its technical performance, operational control in the form of directly affect the performance and efficiency of the bulldozer.
