ZM12 Road Crushing Crawler Small Diggers 1.2 Ton Mini Excavator Micro Hook
Introductions Of ZM12 Road Crushing Crawler Small Diggers 1.2 Ton Mini Excavator Micro Hook
Small excavators are widely used in greenhouse orchards, mountain ditches, rural renovation, indoor and outdoor, construction projects, road finishing and other working conditions.
Generally, it is composed of power device, transmission device, walking device and working device. Principle: Use the bucket to excavate the material above or below the bearing surface, and load it into the transport vehicle or the earth-moving machine unloaded to the stockyard. A self-propelled mining machine that uses a bucket to shovel exfoliated material or minerals from the working face and transport it to a discharge location for unloading. History: It has been more than 130 years since the first manual excavator came out. During this period, it has experienced from steam-driven bucket rotary excavator to electric drive and internal combustion engine-driven rotary excavator, and fully automatic hydraulic excavator using electromechanical-hydraulic integration technology. gradual development 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, which was close to 100%.
