The excavator is a kind of mechanical equipment that can carry out the construction of earth and stone works. It can carry out a variety of engineering operations, such as excavation, transportation and unloading, through different devices. There are many types of excavators, which can be divided into several types according to the use environment and purpose, including wheeled excavators, crawler excavators, small excavators, large excavators, loaders and combined excavators. The following will introduce the knowledge of the excavator in detail.

1.Wheeled excavator

Wheeled excavators are suitable for working on smooth surfaces.It usually adopts four-wheel drive and four-way steering, has high efficiency, speed and flexibility, and is suitable for road construction, water conservancy projects and urban construction and other engineering projects.

2.Crawler excavator

Crawler excavators are generally suitable for work in wilderness and mountainous areas. Because they have better traction and balance, it is more convenient and stable to move over rough terrain and uneven surfaces

3.Mini-excavator

Mini-excavators are widely used and suitable for projects of various sizes.The size of small excavators is relatively small, but its loading capacity and speed are not lower than other types of excavators.

4.Large type (scale) excavator

Large excavators, also known as heavy excavators, are usually used for large engineering projects, such as mines, tunnels and large foundation projects.

5.Loader

Loaders are mechanical devices with large cavities, mainly used for loading and storing materials and earthmoving, suitable for site construction, mining and industrial production. They are generally more flexible, can be moved to different engineering projects, and carry out different material handling

In short, the excavator is a multi-functional mechanical device, which can be divided into multiple types according to its use and function. The excavator usually has high efficiency, mobility and operational flexibility to meet the needs of different types and sizes of engineering projects. By understanding the different types and characteristics of excavators, users can be helped to choose the most suitable equipment for their engineering project needs.
