Cat large excavator
Excavator is a kind of heavy machinery and equipment widely used in engineering construction, mining, farmland water conservancy and other fields. Its classification methods are diverse and can be divided according to different standards. The following are the main classification methods and specific types of excavators:
Classification by transmission mode
Mechanical drive excavator:
Features: The power of the engine is transmitted to the working and running devices through a mechanical transmission system (e.g. gears, chains, etc.).
Application: Early excavators used this method, but now it is gradually being replaced by hydraulic transmission, but it is still used in some specific occasions.
Hydraulic drive excavator:
Features: The hydraulic system is used to transmit power, which has the advantages of smooth transmission, light operation, and compact structure.
Application: The mainstream type of modern excavator, widely used in various engineering construction fields.
General Excavator:
Features: With a variety of working devices, it can adapt to different job requirements.
Application: Widely used in earthworks, stone works, building demolition, etc.
Mining excavator:
Features: Specially designed for mining, with strong excavation power and durability.
Application: large open-pit mines, quarries, etc.
Marine excavator:
Features: Adapt to the water working environment, with waterproof, anti-corrosion and other characteristics.
Application: river dredging, port construction and other water engineering.
