The lowbed semi-trailer is a specially designed semi-trailer used for transporting heavy machinery, large equipment, and other heavy loads. Its design features include:
Frame Structure: It typically uses a concave beam style (or well-type) frame, with the front section being the gooseneck, the middle section being the loading platform, and the rear section being the wheel frame. The gooseneck section is connected to the towing hitch of the tractor, and the rear end is connected to the semi-trailer frame.
Loading and Unloading Method: Traditional lowbed semi-trailers are usually loaded from the rear, but the gooseneck lowbed semi-trailer can achieve a front-loading method, where goods are loaded from the front. This can reduce the difficulty of loading and unloading, and improve the efficiency and safety.
Removable Gooseneck: Some designs allow the gooseneck section to be detached from the semi-trailer, allowing the front end of the semi-trailer to be lowered to the ground for easy loading and unloading of heavy machinery.
Stability and Safety: Due to the low loading platform and low center of gravity, the stability and safety are good, making it suitable for transporting oversized cargo and passing over overhead obstacles.
Load Capacity: Depending on the number of axles and the size of the tires, the load capacity of the gooseneck lowbed semi-trailer can range from 20 to 150 tons.
Regulatory Restrictions: In some areas, such as on highways, semi-trailers with six axles or more are usually limited to a weight of 49 tons.
Technical Specifications: The "Lowbed Semi-trailer Technical Specifications" stipulate the general technical requirements, special requirements, test methods, inspection rules, etc., for lowbed semi-trailers.
Application Scenarios: Suitable for the transportation of various types of machinery, large objects, road construction equipment, large tanks, power station equipment, and various types of steel.
