Product structure of 800kg Mini Excavator

It is generally composed of power device, transmission device, walking device and working device. Principle: Use a bucket to excavate materials above or below the bearing surface, and load them into transportation vehicles or earthmoving machinery that are unloaded to the stockyard. A self-propelled mining machine that uses a bucket to scoop strips or mineral products from the working face and transport them to a dumping site for unloading. History: The first manual excavator has a history of more than 130 years. During this period, it has experienced the development from steam-driven bucket rotary excavators to electric-driven and internal combustion engine-driven rotary excavators, and fully automatic hydraulic excavators using electromechanical and hydraulic integration technology. step-by-step development process. Due to the application of hydraulic technology, there were mounted excavators equipped with hydraulic backhoes on tractors in the 1940s. In the early and mid-1950s, towed full-rotation hydraulic excavators and crawler-type fully hydraulic excavators were developed. . The initial trial production of hydraulic excavators used the hydraulic technology of aircraft and machine tools. They lacked hydraulic components suitable for various working conditions of the excavator. The manufacturing quality was not stable enough and the supporting parts were not complete. Since the 1960s, hydraulic excavators have entered a stage of promotion and vigorous development. Excavator manufacturers and varieties in various countries have increased rapidly, and output has surged. From 1968 to 1970, the output of hydraulic excavators accounted for 83% of the total excavator output, which is close to 100%.
