excavator

Excavator is a kind of earth-moving machinery that uses a bucket to excavate materials above or below the bearing surface, and then loads them into transport vehicles or unloads them to the stockyard. Excavators are composed of power device, working device, rotary mechanism, control mechanism, transmission mechanism, walking mechanism and other structures, which are mostly used for digging materials such as soil, coal and sediment. The three most important parameters are operating weight, engine power and bucket capacity.

The following are the categories of common excavators:

Common excavators are divided into two kinds according to the driving mode: excavators driven by internal combustion engines and excavators driven by electricity. Among them, electric excavators are mainly used in high-altitude hypoxia and underground mines and other flammable and explosive places.

According to the different ways of walking, excavators can be divided into crawler excavators and wheeled excavators.

According to the different transmission methods, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines.

According to its use, excavators can be divided into general excavators, mining excavators, Marine excavators, special excavators and other different categories

According to the bucket, the excavator can be divided into shovel excavator, backhoe excavator, pull shovel excavator and grab shovel excavator. Shovel excavators are mostly used to dig materials above the surface, backhoe excavators are mostly used to dig materials below the surface.
