Gooseneck style flower bar semi-trailer on February 9, 2022
A semi-trailer with a fence structure design is used for the cargo area of the high bar semi-trailer. The types and structures of high column semi trailers are gradually improving. In terms of external structure, there are generally two types of semi-trailer: straight beam and goose neck. The straight beam is commonly known as the "straight plate", and the goose neck beam presents a "Z" shape, commonly known as the "high and low plate". The height difference between the bottom plate of the high and low plates and the goose neck is generally around 200mm. Compared to the straight beam structure, the loading space is larger and the center of gravity of the goods is lower. It is suitable for general cargo transportation with relatively low density and coal transportation in mountainous areas with large road curvature. In standard load transportation, the goose neck part is designed structurally, and the bearing capacity is not significantly different from that of the straight beam in terms of selection.
