Excavators, also known as digging machines, are earth-moving machines that use buckets to dig up materials above or below the bearing surface, 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. Working weight is one of three important parameters of excavator (engine power, bucket capacity and working weight). The working weight determines the level of the excavator and the upper limit of the digging force of the excavator. Excavation force ≦ m; Working weight m: the adhesion coefficient between the ground and the track. If the digging force exceeds this limit, the excavator will slip and be pulled forward in the case of backhoe, which is very dangerous. In the case of front shovel, the excavator will slip back.

Second-hand excavators from the development of construction machinery in recent years, excavators have developed rapidly, 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.
