Excavators, also known as excavating machinery, are earthmoving machinery that uses buckets to excavate materials above or below the bearing surface, and load them into transport vehicles or unload them to stockpiles. The materials excavated by the excavator are mainly soil, coal, silt, soil and rock after pre-loosening. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction.
