What types of excavators are there?

There are two common driving methods for excavators: internal combustion engine driven excavators and electric powered excavators. Electric excavators are mainly used in high-altitude hypoxia, underground mines, and other flammable and explosive places.
According to different walking modes, excavators can be divided into tracked 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 purpose excavators, mining excavators, marine excavators, special excavators, etc
According to the bucket, excavators can also be divided into front shovel excavators, backhoe excavators, pull shovel excavators, and grab shovel excavators. Shovel excavators are mostly used to excavate materials above the surface, while backhoe excavators are mostly used to excavate materials below the surface.
Backhoe excavator
The backhoe type is the most common one we have seen, with a backward and downward force to cut the soil. It can be used for excavation below the shutdown working surface, with basic operation methods including trench end excavation, trench side excavation, straight excavation, curve excavation, maintaining a certain angle excavation, ultra deep trench excavation, and trench slope excavation.
Shovel excavator
The shovel action form of a front shovel excavator. Its characteristic is "advancing upwards and forcing soil cutting". The front shovel has a large excavation force and can excavate soil above the parking surface. It is suitable for excavating dry foundation pits with a height greater than 2m, but an up and down slope must be set up. The excavation bucket of the front shovel is larger than that of the same equivalent backhoe excavator. It can excavate Class I to III soil with a water content of no more than 27%, and cooperate with dump trucks to complete the entire excavation and transportation operation. It can also excavate large dry foundation pits and soil mounds. The excavation method of a front shovel excavator varies depending on the relative position of the excavation route and transportation vehicles. There are two ways to excavate and unload soil: forward excavation and lateral unloading; Forward excavation and reverse unloading.
Dragline excavator
A dragline excavator is also known as a cable shovel excavator. The characteristics of its excavation are: "backward downward, self weight cutting of soil". Suitable for excavation of Class I and II soil below the parking surface. When working, use inertial force to throw the bucket out and dig farther, with a larger excavation radius and depth, but not as flexible and accurate as a backhoe. Especially suitable for excavating large and deep foundation pits or underwater excavation.
Grab shovel excavator
Grab excavator, also known as grab excavator. The characteristics of its excavation are: "straight up and straight down, cutting soil by self weight". Suitable for excavation of Class I and II soil below the parking surface, commonly used in soft soil areas for excavation of foundation pits, open caissons, etc. Especially suitable for digging deep and narrow foundation pits, dredging old channels, and extracting silt from water, or for loading loose materials such as crushed stones and slag. There are two excavation methods: trench side excavation and positioning excavation. If the grab bucket is made into a grating shape, it can also be used for loading ore blocks, wood chips, wood, etc. in a wood storage yard.
