Excavators are driven by internal combustion engines or electric motors, depending on the method of operation. Electric excavators are the most common type of excavator used in high altitude hypoxia, underground mines, and other flammable and explosive environments.
Excavators can be classified into three categories based on their size: large excavators, medium excavators, and mini excavators.
Excavators can be divided into two categories based on how they walk: crawler excavators and wheel excavators.
Excavators can be divided into two categories based on the transmission modes they use: hydraulic excavators and mechanical . Mechanical excavators are primarily used in large mines, but they are also used in smaller mines.
Excavators can be classified into a variety of categories, including general excavators, mining excavators, marine excavators, special excavators, and so on.
Excavators can be classified into four types based on the bucket they use: shovel excavators, backhoe excavators, dragline excavators, and grab shovel excavators. Front shovel excavators are primarily used to excavate materials above the surface of the ground, whereas backhoe excavators are primarily used to excavate materials below the surface of the ground
1. The backhoeThe backhoe is the most common type of machine we've seen, moving backwards and downwards, forcing soil to be cut. It can be used to excavate below the stop working surface of a structure. The following are the fundamental excavation methods: trench end excavation, trench side excavation, straight line excavation, curve excavation, excavation at a specific angle, ultra-deep trench excavation, and trench slope excavation..
2. A shovel and an excavator
The shovel excavator is distinguished by its shovel action. Its distinguishing feature is that it advances upward and must cut the soil. The front shovel has a large digging force and can excavate soil up to the stop surface, if necessary. When excavating dry foundation pits with a height greater than 2m, it is necessary to construct ramps up and down. With the front shovel, you can excavate a bucket that has a water content of no more than 27%, which is larger than with the backhoe that has the same equivalent.
