Designed for the safe and legal transport of heavy machinery, the Chengda 3-Axle Low Bed Semi Trailer offers a loading capacity ranging from 40T to 80T. The deck height is kept as low as 850mm to accommodate tall excavators and wheel loaders without exceeding height restrictions. We use Q345B manganese steel for the main beams, processed through automatic submerged arc welding. This ensures the gooseneck and platform withstand significant torsional stress, with a documented deflection rate of less than 10mm under full 80T static load tests.

The trailer chassis integrates reinforced cross members spaced at 500mm intervals, providing a solid foundation for concentrated loads. Customers can choose between FUWA or premium BPW axles rated at 13T or 16T per line, paired with a heavy-duty mechanical suspension. For sensitive cargo, we offer an air suspension option to reduce road shock. A 2019 field study in Kenya showed our standard leaf-spring configuration maintained structural integrity over 15,000km of unpaved mine access roads.

Standard features include a mechanical spring-assisted hydraulic gooseneck for fast equipment loading and optional outriggers for extra-wide loads. The standard delivery timeline for a 3-axle unit is 25 to 30 days from order confirmation. We stock critical components like axles and landing gear to support urgent partial shipment requirements.
