Equipped with an eight section octagonal high-strength steel synchronous telescopic working arm, the maximum working height can reach 22 meters, which can accurately cover various high-altitude work scenarios without the need for additional scaffolding, greatly improving work efficiency. It is suitable for high-altitude advertising installation, power line maintenance, large venue maintenance and other high-altitude work needs, taking into account both work height and work range. The working arm supports 360 ° full rotation, and is equipped with front and rear V-shaped thick support legs, which can be adjusted separately to flexibly avoid obstacles on the work site and adapt to complex work environments such as urban streets and factory areas; Two wheelbase chassis options, 2800mm and 3280mm, can be selected for modification. The body structure can be flexibly adapted to different work scenarios, further expanding the coverage of work and achieving precise positioning in complex environments. The size of the work platform is 1600 × 700 × 1000mm, with a rated load of 200kg. It can carry 1-2 workers and required tools for synchronous operation, without the need for repeated up and down trips, reducing work time; The upper seat is only operated and used in the working state, and no personnel are seated during the driving process. It meets the requirements of manned and cargo coordination for mid to high altitude operations, balancing practicality and standardization. The working arm is made of high-strength steel, matched with a straight through 180 double-layer beam, 3/8+6 reinforced leaf spring, and 5T rear axle, with excellent load-bearing performance, sturdy structure, and strong deformation resistance; Integrated design of the entire vehicle, no need for secondary modification, smooth extension and retraction of the boom during operation, stable platform, ensuring operational accuracy and personnel safety, and adapting to long-term high-frequency mid to high altitude operation requirements
