Excavators, also known as excavators, hook machines and backhoe excavators, are earth-moving machines that use buckets to excavate materials above or below the bearing surface, and load them into transport vehicles or unload them into the yard. The materials excavated by excavators are mainly soil, coal, sediments and pre-loosened soil and rocks. 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. The three most important parameters of excavator are working weight (mass), engine power and bucket capacity. The first hydraulic excavator was successfully invented by Boquelin Factory. Due to the application of hydraulic technology, in the 1940s, there appeared a hanging excavator equipped with a hydraulic backhoe on tractors.
