Common excavators include internal combustion engine-driven excavators and electric-driven excavators according to their driving modes. Among them, electric excavators are mainly used in plateau anoxia, underground mines and other flammable and explosive places.

According to different sizes, excavators can be divided into large excavators, medium excavators and small excavators.

According to different walking methods, excavators can be divided into crawler excavators and wheeled excavators.

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

According to the purpose, excavators can be divided into different categories such as general excavators, mining excavators, marine excavators, and special excavators.

According to the bucket, excavators can be divided into front shovel excavators, backhoe excavators, dragline excavators and grab shovel excavators. Front shovel excavators are mostly used to excavate materials above the ground surface, while backhoe excavators are mostly used to excavate materials below the ground surface.

Do you know what are the common faults of excavators?

How should we prevent and protect our machinery before failure occurs?

How do we deal with these emergency failures if they occur?

Excavator, also known as excavation machinery, also known as excavator, is a bucket to dig above or below the bearing surface of the material, and loaded into transport vehicles or unloading to the stacking field of earthwork machinery.

The materials excavated by the excavator are mainly soil, coal, sediment, and the pre-loosened soil and rock. From the development of construction machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction. The three most important parameters of the excavator are: operating weight (mass), engine power and bucket capacity.
