The 5-Line 10-Axle Hydraulic Gooseneck Lowbed Semi-Trailer is a professional transportation solution specifically designed for extreme heavy-haul challenges. Featuring a 5-line, 10-axle configuration with a hydraulic gooseneck system, this trailer is optimized for transporting non-detachable ultra-heavy cargo such as bulldozers, large excavators, transformers, wind power equipment, and industrial machinery. The 5-line, 10-axle design evenly distributes enormous cargo weight across 40 tires, effectively reducing ground pressure and protecting roads and bridges. The multi-axle hydraulic steering system greatly enhances maneuverability in complex environments including narrow construction sites, mines, ports, and mountain roads, offering a small turning radius and flexible handling. The hydraulic gooseneck features a detachable design with a low loading deck height and a low center of gravity. Heavy equipment (such as crawler cranes) can be loaded directly from the front of the trailer without the need for external cranes or complicated ramps, significantly improving loading and unloading efficiency.
