Wing car, also known as exhibition wing car, is an improvement of ordinary box car. It is a specialized vehicle that can open the wing plates on both sides of the carriage through manual or hydraulic devices. Due to its advantages of fast loading and unloading speed, high efficiency, and side loading and unloading, it has become a favored transportation tool for modern logistics enterprises. Due to the application of a large number of lightweight new materials in the wingspan vehicle series in recent years, the weight of the carriage has been reduced. In addition, the carriage design is beautiful and the transportation of goods is safe and reliable. It is expected to occupy a place in the logistics transportation market. The principle is to achieve lifting by discharging the battery and driving the hydraulic system through the power unit. The lifting height can be extended beyond the carriage, approaching a 90 degree angle. The top, front panel, and rear door structure of the car are the same as those of an iron corrugated box car, and the sides are composed of flip panels, upper panels, and lower panels.
