Excavators, also known as excavating machinery, also known as excavators, are earthmoving machines that use buckets to dig materials above or below the surface of the bearing, and load them into transport vehicles or unload them to the storage yard. The materials excavated by excavators are mainly soil, coal, sand, and soil and rock after pre-loosening. From the perspective of 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. First of all, excavators can be used for construction activities on construction sites. For example, highways, Bridges, buildings, aquaculture ponds, underground engineering, emergency excavation, etc., are inseparable from excavators.
Secondly, excavators are also needed on many occasions in rural areas, such as clearing land, building roads, digging reservoirs and ponds, etc., which are inseparable from excavators.
In addition to digging operations, the excavator can also be used for loading operations, which can be used to load soil, sand and stones
