What Types of Excavators are There?

Mar. 12, 2020

There are two types of Excavator according to the driving mode: internal combustion engine driven excavator and electric driven excavator. The electric excavator is mainly used in plateau hypoxia and underground mines and other flammable places.

1. According to the size, excavators can be divided into large excavators, medium excavators and small excavators.

2. According to different walking methods, excavators can be divided into Track Excavator and wheel excavators.

3. 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. Hydraulic excavator generally consists of three parts: working device, upper body and lower body. According to its structure and application, it can be divided into: crawler, tire, walking, full hydraulic, semi-hydraulic, full swing, non-full swing, general, special, articulated, telescopic boom and other types.

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

5. Divided by bucket, the excavator can be divided into forward shovel, back shovel, drag shovel and shovel shovel. The front shovel excavator is mostly used to dig materials above the ground, and the back shovel is mostly used to dig materials below the ground.

(1) Backhoe excavator Backhoe type is the most common we have seen. It can be used for excavation below the stop working surface. The basic operation methods are: trench end excavation, trench side excavation, straight line excavation, curve excavation, excavation at a certain angle, ultra-deep trench excavation and trench slope excavation.

(2) Front shovel excavator

Shovel action form of a shovel. Its characteristics are "forward and upward, forced cutting." The front shovel has a large digging force and can excavate the soil above the stopping surface. It is suitable for excavating dry foundation pits with a height of more than 2m, but an up and down slope must be provided. The bucket of the front shovel is larger than the bucket of the equivalent backhoe excavator. It can dig a water content of not more than 27%.

To three types of soil, and cooperate with dump trucks to complete the entire excavation and transportation operation, and can also excavate large dry foundation pits and mounds. The excavation method of the front shovel is based on the difference between the excavation route and the relative position of the transport vehicle. There are two methods for digging and unloading: forward digging, lateral unloading; Unloading soil.

(3) Drag shovel: Drag shovel is also called cable shovel. Its digging characteristics are: "backward and downward, cutting by weight." It is suitable for excavation of Class I and II soil below the stop surface. When working, the inertia force is used to throw the bucket out. The digging is far away, the digging radius and digging depth are large, but not as flexible and accurate as the backhoe. Especially suitable for excavating large and deep foundation pits or digging underwater.

(4) Shovel shovel: Shovel shovel is also called bucket shovel. It is suitable for excavating class I and II soil below the stop surface, and it is often used for excavating foundation pits and sinkholes in soft soil areas. It is especially suitable for digging deep and narrow foundation pits, dredging old channels and dredging sludge in water, or for loading loose materials such as crushed stones and slag.

The above are the types of excavators introduced by Excavator Manufacturer.
