Compared with the domestic similar products, this product uses low power MCU with LCD and high energy lithium battery, which has the advantages of anti-interference, anti attack and long service life. The instrument also has a wireless transmission module, and designed a wireless relay and metering and charging management system to achieve remote automatic meter reading within the scope of intelligent communication. "Double acting" liquid muffler with alternating transmission system, compound muffler manipulator, manipulator and other technologies; intelligent automatic control technology, through demonstration and reproduction technology, realizes unmanned operation such as loading and unloading, stacking and crushing dangerous goods. " Development and application of double acting full hydraulic driving device: two power forms (internal combustion engine and 380V motor) are installed on the same equipment. The function of energy saving, pollution reduction and fire prevention is realized. The application of mechatronics technology in tractor is the forerunner to realize tractor intelligence.
