A high-altitude work vehicle (also known as a high-altitude work platform vehicle) is a special engineering vehicle based on the modification of a second-class automobile chassis, equipped with a hydraulic lifting arm, a manned work platform, and a safety protection system. It is specifically designed for installation, maintenance, cleaning, and emergency repair at heights of 3-45 meters. Its core positioning is a "mobile high-altitude safety work platform", with the core advantages of "fast lifting+stable load-bearing+flexible adjustment". It ensures the safety of workers through anti fall, overload protection and other devices, replacing traditional scaffolding, cloud ladders and other tools, greatly improving the efficiency and safety of high-altitude operations
