Good price, welcome inquiry!Excavators, also known as excavating machinery, also known as excavators, are earthmoving machinery that use buckets to dig materials above or below the surface of the bearing and load them into transport vehicles or unload them to the storage yard. The materials excavated by excavators are mainly soil, coal, sand, and soil and rock after pre-loosening. From the perspective of the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of excavators are: operating weight (mass), engine power and bucket capacity.
The original excavator is manual, from the invention to 2013 has been more than 130 years, during which it has experienced the gradual development process from steam driven bucket rotary excavator to electric drive and internal combustion engine driven rotary excavator, the application of mechanical and electrical hydraulic integration technology of fully automatic hydraulic excavator. The first hydraulic excavator was successfully invented by the Poclin factory in France. Due to the application of hydraulic technology, in the 1940s, there was a hydraulic backhoe mounted on the tractor. In 1951, the first fully hydraulic backhoe excavator was launched by the Poclain (Poclain) factory in France, thus creating a new space in the field of technical development of excavators, and in the early and mid-1950s, towed full-rotary hydraulic excavators and crawler full-hydraulic excavators were successively developed. The initial trial production of hydraulic excavator is using the hydraulic technology of aircraft and machine tools, the lack of hydraulic components suitable for various working conditions of the excavator, the manufacturing quality is not stable enough, and the accessories are not complete. Since the 1960s, hydraulic excavators have entered the stage of promotion and vigorous development, and excavator manufacturers and varieties in various countries have increased rapidly, and production has soared. From 1968 to 1970, the output of hydraulic excavators has accounted for 83% of the total output of excavators, which is close to 100%. The first generation of excavators: the emergence of electric motors and internal combustion engines has made excavators have advanced and suitable electric devices, so various excavator products have been born. In 1899, the first electric excavator appeared. After the First World War, diesel engines were also used in excavators, and this mechanical excavator driven by a diesel engine (or electric motor) was the first generation of excavators. The second generation excavator: with the widespread use of hydraulic technology, the excavator has a more scientific and applicable transmission device, and the hydraulic transmission instead of the mechanical transmission is a big leap in excavator technology. In 1950, the first hydraulic excavator in Germany was born. Mechanical transmission hydraulic is the second generation of excavators. The third generation excavator: the wide application of electronic technology, especially computer technology, makes the excavator have an automated control system, and also makes the excavator develop in the direction of high performance, automation and intelligence. The germination of mechatronics occurred around 1965, and the adoption of mechatronics technology in mass production of hydraulic excavators was around 1985, when the main purpose was to save energy. The electronic excavator is the symbol of the third generation excavator. Excavator industry manufacturers can be roughly divided into four categories. More than 70% of domestic excavators are occupied by foreign brands, and domestic brands are still dominated by small digging and medium digging, but the share of domestic excavators is gradually increasing, increasing 3.6% in 2012.
