A semi-trailer, also known as a trailer, is a common heavy-duty vehicle in modern transportation, primarily used for long-distance hauling of bulk goods. Its defining characteristic is that it lacks front wheels and is towed by a tractor unit, relying on the tractor and rear axles for support during transport.
Semi-trailers are designed for high load capacity and operational flexibility. The articulated connection between the tractor and trailer allows for easier maneuvering on curves and narrow roads, while still accommodating larger volumes of cargo.
Additionally, semi-trailers typically feature multiple axles and are constructed from high-strength steel to ensure stability and safety during long-distance transport. Various types of semi-trailers are available to meet different transportation needs, including flatbed, box, refrigerated, and hazardous material carriers.
In summary, semi-trailers are indispensable in modern logistics due to their high load capacity, flexible articulation, and adaptability to diverse transport requirements.
