[0002] Mining dump trucks are key equipment in open-pit mining and large-scale earthwork construction, with the characteristics of heavy load and high work efficiency. As the hinge point between the cargo box and the frame, the rear tipping seat plays an important role in the work links of the mining dump truck, such as material transfer, transportation, and unloading. With the continuous increase in the cargo tonnage of mining dump trucks, the rear tipping seat is the main working load-bearing component, and the structural strength requirements for the rear tipping seat are gradually increasing.
