excavator

Excavators, also known as excavating machinery, are excavating materials above or below the surface of the plane with buckets, and are loaded into transport vehicles or earthmoving machinery that is unloaded to the stockyard.

The composition of the excavator

Common excavator structures include powerplants, work devices, swing mechanisms, steering mechanisms, transmission mechanisms, travel mechanisms, and auxiliary facilities.

From the appearance point of view, the excavator consists of a working device, an upper turntable, and a walking mechanism. Classification of Excavators The following are the categories of common excavators:

Excavator classification 1: Common excavators are driven by two types: internal combustion engine driven excavator and electric driven excavator. Among them, electric excavators are mainly used in high altitude hypoxia and underground mines and other flammable and explosive places.

Excavator classification two: According to the different walking methods, excavators can be divided into crawler excavators and wheel excavators.

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

Excavator Category 4: According to purpose, excavators can be divided into general excavators, mining excavators, marine excavators, special excavators and other different categories.

Excavator Category 5: According to the bucket, the excavator can be divided into front shovel excavator and backhoe excavator. The shovel shovel is mostly used for excavating materials above the ground surface. Backhoes are used to excavate materials below the surface.

Backhoe

The backhoe is the most common one we have ever seen. It can be used for excavation below the shutdown surface. The basic operation methods include: trench excavation, trench side excavation, straight line excavation, curve excavation, maintaining a certain angle of excavation, ultra deep trench excavation, and trench slope excavation.

Shovel excavator

Shovel excavator shovel action. It is characterized by "going up and forcibly cutting earth." The digging force of the shovel is large, and the earth above the stop surface can be excavated, and it should be used for excavation of dry foundation pits with a height of more than 2m. However, up and downhill ramps must be provided. The bucket shovel is larger than the excavator with the same amount of backhoe. It can excavate one to three types of soil with water content no more than 27%. It can complete the whole excavation and transport operations with the dump truck and can also excavate. Large dry pits and mounds. The excavation method of the shovel shovel is different according to the relative position of the excavation route and the transportation vehicle. There are two methods for excavation and unloading the soil: forward excavation, lateral unloading, forward excavation, and Displace earth.
