Small excavators are widely used in greenhouse orchards, mountain ditches, rural renovation, indoor and outdoor, construction projects, road finishing and other working conditions.

Due to the application of hydraulic technology, there was a mounted excavator equipped with a hydraulic backhoe on a tractor in the 1940s. In the early and mid-1950s, a trailed azimuth hydraulic excavator and a crawler full hydraulic excavator were successively developed. . The initial trial-produced hydraulic excavator adopts the hydraulic technology of aircraft and machine tools, lacks hydraulic components suitable for various working conditions of the excavator, the manufacturing quality is not stable enough, and the supporting parts are not complete. Since the 1960s, hydraulic excavators have entered a stage of promotion and vigorous development. The number of excavator manufacturers and varieties in various countries has increased rapidly, and the output has soared. From 1968 to 1970, the output of hydraulic excavators accounted for 83% of the total output of excavators, which was close to 100%.
