There is a wide range of excavators available in the market, and according to different classifications, excavators can be divided into various types, each of which has its own specific use and function. 

Here are some common types of excavators and their applications:

1. Backhoe Excavator:

   - The most common type of excavator, suitable for most earthworks such as digging trenches, filling roadbeds, loading materials, etc.

2. front shovel excavator:

   - Suitable for large-scale earthworks, especially deep pit excavation and high-grade operations, such as mining.

3. Grab shovel excavator:

   - Used to grab loose materials, such as coal, ore, garbage, etc., commonly used in ports, power plants and large warehouses.

4. pull shovel excavator:

   - For large area land leveling and excavation, such as farmland renovation and large infrastructure projects.

5. long arm excavator:

   - With a long arm span, it is suitable for deep pits or long-distance work, such as tunnel construction and deep well excavation.

6. short-arm excavator:

   - With a shorter arm span, it is suitable for space-restricted operation environment, such as urban construction site, basement excavation.

7. wheeled excavator:

   - Equipped with wheels, easy to move on the construction site, suitable for highway construction, municipal engineering, etc.

8. crawler excavator:

   - Fitted with tracks, with good off-road capability and stability, suitable for various terrains and environments.

9. Float excavator:

   - Can operate on water or in swampy areas, such as wetland development and river dredging.

The role of the excavator mainly includes:

- Fast and efficient earth excavation, loading and transportation.

- Land leveling, trench digging, pit excavation in various projects.

- Cooperate with other equipment to carry out special operations, such as demolition, crushing and shearing.

- Operate in special environment, such as water, high altitude, narrow space, etc.

Excavators are the core equipment in earthmoving projects, and their high efficiency and versatility make them play an important role in many fields, such as construction, mining, and infrastructure 

construction.
