An excavator, also called an excavator, is also called an excavator. They are used to excavate the material above or below the surface of the carrier and load it into the earthmoving machinery of the transport vehicle or unload it to the yard. The materials excavated by the excavator are mainly soil, coal, sediment and pre-drawn 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.
However, when the existing excavator is working, the up and down movement of the power arm will drive the excavator's cab to vibrate, thereby exerting a force on the seat of the cab, and the force will act on the operator above the seat. The health of the operator also affects the operator's operation of the excavator. To this end, we have proposed a shock absorber for excavator seats.
