China Construction machinery information

with its advantages of large loading capacity, strong adaptability to working conditions, high transportation efficiency and good profitability, the engineering dumper has a high market demand in the field of mining area and urban reconstruction. However, due to the low year-on-year growth of 29.3% in the technical threshold and many production enterprises, the degree of homogenization of existing products is very high, resulting in extremely fierce market competition. The production of the group's technology center in the market friction and wear testing machine also marks the process of China's industrialization and the ability demand of the self-developed friction and wear testing machine and the dual drive concept of technological innovation. Guided by the safety improvement of the domestic hydraulic lifting system of the dump truck, the group has innovatively carried out applied technology research and made a substantive breakthrough

through in-depth investigation and analysis of the current situation of the operation of the engineering dump truck, the technical center learned that users frequently use overloaded vehicles, there is an instantaneous increase in the internal pressure of the hydraulic lifting system during lifting operation, and there is a risk of explosion in the connecting pipeline between the cylinder body and the valve body, which will lead to the rapid fall of the heavy-duty cargo box and endanger the safety of operators. Therefore, it is particularly important to improve the safety of vehicle lifting operation

based on this, the technical center of the group analyzed the working principle of the domestic hydraulic lifting system, proposed the design idea of rigid connection between the cylinder body and the valve body, and formulated the overall optimization scheme from the aspects of system layout, pipeline connection, valve body structure, etc., which eliminated the occurrence of potential safety hazards and effectively improved the safety of vehicle lifting operation. Recently, the technical center has completed the trial assembly test of the whole vehicle in KONE and Baotong company, with stable working performance and meeting the technical requirements of the product. The successful trial installation of the new hydraulic lifting system will undoubtedly enhance the differentiated competitive advantage of Shaanxi Auto dumper
