What are the classifications of excavators?

Classification of excavators: There are two common excavators: internal combustion engine-driven excavators and electric excavators. Among them, electric excavators are mainly used in flammable and explosive places such as plateau hypoxia and underground mines.

Classification of excavators 2: According to different walking modes, excavators can be divided into crawler excavators and wheeled excavators.

Classification of excavators 3: According to different transmission modes, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines.

Classification of excavators: According to the purpose, excavators can be divided into general excavators, mining excavators, marine excavators, special excavators and other different categories.

Excavator-structure

An excavator consists of a bucket, a bucket column, a slewing arm, legs or supporting wheels and a hydraulic system (see figure). The bucket is hinged with the bucket column, and the bucket column is hinged at the end of the rotating arm. The hydraulic system controls the lifting of the boom and the rotation in the horizontal plane, the rotation of the bucket column in the vertical plane, the lifting of the support, and the changes of the bucket's digging, lifting and unloading state, so that the bucket can dig the earthwork 3 ~ 4 meters above and below the ground and unload the soil to the designated position.

According to the power of the tractor, the capacity of the excavator bucket is about per 15 kW 0. 1 m3. After the bucket is unloaded, it can also be equipped with various working parts such as grab bucket, multi-tooth grab bucket parts or hooks, which can be used for various operations such as material loading, lifting and loading.
