The vehicle has optimized the vehicle layout and exterior covering parts to ensure that the product has a large operating range, while the vehicle weight is controlled at 18 tons, achieving the limit matching of 4X2 chassis; Flexible and convenient operation, a variety of operation options. The operation platform can be operated by remote control, and the emergency stop button is set separately in the platform. Both the turntable and the remote control can realize the starting and extinguishing control of the engine. The seven-section telescopic arm adopts the heptagonal structure in cross-section and the bending structure in the side of the arm. While improving the performance, the arm body has lighter weight and better operation stability. The telescopic mechanism adopts high strength cable, lighter weight, stronger carrying capacity and higher reliability. It can expand the high-strength aluminum alloy working platform, the width can reach more than 3m after expansion, and the low place can reach the ground, which is convenient for loading and unloading of goods, and the high place can be used by many people for high-altitude collaborative work. Set the horizontal leg status detection, the vehicle can automatically limit the amplitude of the arm according to the extension length of the horizontal leg, without the use of very dangerous forced function, you can complete the job, and the operation is more comfortable.
