A Brief History of Excavators

It has been more than 130 years since the first manual excavator came out. During this period, it has experienced the gradual development from steam-driven bucket rotary excavators to electric-driven and internal-combustion-engine-driven rotary excavators, and fully automatic hydraulic excavators using electromechanical-hydraulic integration technology. process.
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, and it is now close to 100%.
