Find out the cause of concrete pump mechanical hydraulic system heating, put forward specific and effective technical measures to ensure that the temperature of concrete pump mechanical hydraulic system under different climate conditions is below 70 ℃ muffler monopoly. In view of the existing product structure, the influence factors of system noise are comprehensively studied and analyzed, and feasible system improvement scheme is put forward and verified, so as to further reduce the noise index of the whole machine and make it meet the requirements of CE and other relevant standards. A large number of electrical components such as motors and coils are installed in the crane cab and control room. The electromagnetic interference of muffler ventilation will inevitably affect the PLC and bus data transmission and affect the normal operation of the equipment. The purpose of this project is to accurately detect the characteristics of interference and develop and improve related products. Due to the lack of necessary safety measures, many cranes can easily touch the high-voltage electricity when the boom is retracted, rotated, and luffed, resulting in vehicle damage and human death.
