History of bulldozers

Swamp hydrostatic dozer as an important variety of construction machinery, for workers to alleviate the heavy manual labor, improve the level of mechanization of construction, speed up construction progress, promote the development of various undertakings, it has played a big role, therefore, to develop a hydraulic excavator, for improving labor productivity and accelerate the development of the national economy is significant.

Chinese Earthmover production, after the founding of New China only started. Earth-moving equipment was originally installed on agricultural tractors. With the development of the national economy, large-scale mining, water conservancy, power plants and transportation sector demand for medium and large track-type tractors is increasing, China's medium and large Crawler Earthmover Manufacturing Although great progress, but it has been unable to meet the needs of national economic development. To this end, since 1979, China has from Japan's Komatsu and Caterpillar Crawler bulldozer introduced the production technology, process specifications, technical standards and material system, digestion and absorption through research and key technologies, in order to form the current 20th century 80--90 years Komatsu technology products for leading pattern.
