An aerial work truck (also known as an aerial work vehicle) is a special-purpose vehicle equipped with a retractable/foldable work platform. Based on a truck chassis, it controls the lifting, lowering, and rotation of the platform through a hydraulic/electric system to perform high-altitude operations (usually 6-40 meters) such as installation, maintenance, and emergency rescue. It is a core equipment in industries such as municipal administration, construction, electric power, and communications.
