As an important earthmoving construction machinery, excavators play an irreplaceable role in engineering construction, mining, emergency rescue and other fields. The following is a detailed introduction to excavators:
I. Basic Definition and Functions
Definition: Excavators, also known as excavation machinery or excavators, are used to excavate materials above or below the bearing surface with a bucket and load them into transportation vehicles or earth machinery unloaded to the stacking yard.
Function: Excavators have various functions such as crushing, loading and unloading, lifting, piling, etc. They are one of the main mechanical equipment in earthmoving engineering and are known as the "King of Construction Machinery". In engineering, excavators account for about 60% to 75% of the workload.
II. Main types
Classified by way of walking:
Crawler excavator: With good stability and passability, it is suitable for various complex terrains, such as muddy mountain roads, sandy land surfaces, etc. It is a common "big guy" on construction sites, and is often used for earthwork excavation, mining area mining, underground operations, etc.
Wheeled excavator: Strong mobility, suitable for use in urban roads and short-distance transfers, and will not damage urban roads. Commonly used in urban construction, small construction sites, etc.
Mini excavator: Small size, flexible operation, suitable for small spaces and fine operations, such as landscaping, indoor demolition, etc.
Amphibious excavator: Equipped with a buoy system, it can be used in shallow water areas and wetland construction, such as river dredging, wetland development, water conservancy projects, etc.
