Bulldozer is tracked or tyred tractor tractor special chassis as the host

In recent years, with the rapid development of hydraulic integration technology, the traditional mechanical, swamp hydraulic crawler dozer of the operation is complicated, labor-intensive, low productivity, system failures and other shortcomings more so can not meet the requirements of production operations, the development of intelligent construction machinery has become a trend. With the continuous development of science and technology, hydraulic drive bulldozers  increasingly showing strong vitality, foreign hydraulic drive technology matures, more and more applications in the bulldozers, a great tendency to replace the traditional forms of transmission.

Swamp dozer is a crawler tractor or tractor tire special chassis as the host, together with the suspension blade (some also have ripper apparatus) of one self type 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. Bulldozer 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.
