Excavator, also known as excavating machinery, also known as excavator, is an earthmoving machinery that uses a bucket to excavate materials above or below the bearing surface, and loads them into transport vehicles or unloads them into a storage yard.
The materials excavated by excavators mainly include soil, coal, sediment, as well as pre loosened soil and rocks. From the development of construction machinery in recent years, the development of excavators has been relatively fast, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator are operating weight (mass), engine power, and bucket capacity.
