Excavator is widely used in earthmoving machinery, its official name is digging machinery or excavator. It is able to efficiently shovel materials above or below the surface of the machine, whether it is soil, coal, sand, or pre-loosened soil and rock, which can be easily handled. In recent years, with the rapid development of construction machinery technology, excavator with its excellent performance and adaptability, has gradually become an indispensable important machinery in engineering construction. The three key indicators to evaluate the performance of an excavator, including its operating weight, engine power and bucket capacity, are crucial.
(1) According to the driving method, the excavator has two kinds of internal combustion engine drive and electric drive. Internal combustion engine driven excavators are widely used, and electric driven excavators are suitable for special environments such as low oxygen and underground mines.
(2) According to the size, excavators can be divided into large, medium and small. Excavators of different sizes have their own applications in engineering.

(3) According to the walking mode, the excavator has two kinds of crawler type and wheel type. Crawler excavators are suitable for working in complex terrain, while wheeled excavators are more convenient for driving on flat roads.
(4) According to the transmission mode, excavators can be divided into hydraulic excavators and mechanical excavators. Hydraulic excavators are widely used, while mechanical excavators are mostly used in large mines.
(5) According to the use of the excavator, there are general, mining, Marine, special and other categories. Each type of excavator has its own specific application scenario.
(6) Finally, according to the different buckets, excavators can be divided into positive shovel, backhoe, pull shovel and grab shovel. Shovel excavators are often used to dig materials above the surface, while backhoes are suitable for digging materials below the surface.Excavator
