4-Axle Lowbed Semi Trailer

This 4-axle lowbed semi trailer is a professional heavy-duty transport equipment designed for oversized and overweight cargo. Different from ordinary flatbed trailers, it adopts ultra-low deck height design to lower the center of gravity of cargo, ensuring high stability during transportation. Equipped with four-axle load balancing structure and high-strength steel beam, it supports super heavy load up to 80-120 tons. Widely used for transporting excavators, loaders, cranes, engineering machinery, steel structures and oversized equipment. It adapts to complex road conditions and long-distance freight in Africa, Southeast Asia and other emerging markets.
