Introduction of 3 Axle Lowbed Trailer for Sale
Lowbed trailers are usually used to transport heavy vehicles such as guiding vehicles, buses and other special vehicles, railing vehicles, mining machineries, forestry machineries, agricultural machineries such as excavators, bulldozers, loaders, pavers, cranes, and other heavy goods. The lower their center of gravity, the better their stability and safety, and the stronger their ability to transport ultra-high goods and pass overhead obstacles.
Design of 3 Axle Lowbed Trailer for Sale
The lowbed trailers usually adopt a four-beam frame structure with front section of the frame is gooseneck. The traction pin of the front section of the gooseneck is connected with the traction saddle on the tractor, and the rear end of the gooseneck is connected with the trailer frame. The middle section is the cargo platform, which is also the lowest part of the frame. The rear end is the wheel frame including wheels. When loading mechanical equipment onto a lowbed trailer, it is usually loaded from the rear end of the semi-trailer. That is, move the mechanical equipment from the rear wheel frame or remove the wheels, and then fix the mechanical equipment on the semi trailer. Lowbed trailers are also widely used for the transportation of various mechanical equipment, large objects, highway construction equipment, large tanks, power station equipment, and various steel products.
Structure of 3 Axle Lowbed Trailer for Sale
The Series of lowbed trailers consist of flatbed type, four beam type, and tire exposed structure. All of their longitudinal beams adopt flat type or gooseneck type. The frame is stepped and the longitudinal beam section is I-shaped, which has the characteristics of high stiffness and high strength. The main platform of the frame pallet is low, which ensures the stability of transportation and is suitable for carrying all kinds of construction machinery, large equipment and steel. The typical axle structures are three axles, double axles, or rigid suspension. A mass balance block is installed between the front and rear leaf springs, which can change the deflection of the front and rear leaf springs with equal amount, and balance out the stress of the front and rear axles. The entire lowbed trailer adopts advanced computer-aided design software to optimize its function, which is flexible and diverse. The bearing surface of the frame is designed according to the user's requirements to for transportation of various special goods. The trailer is usually divided into semi-trailer and full semi-trailer
Things to Pay Attention to 3 Axle Lowbed Trailer for Sale
The lowbed trailer’s axles are placed behind the center of gravity of the trailer so the weight can be distributed evenly. The trailer is equipped with a coupling device that can transfer horizontal or vertical forces to the tractor. The front of the trailer rests on the rear platform of the tractor. Nowadays, the trailers are generally no longer than 13 meters. Lowbed trailer must have a water spraying system when leaving the factory because in long-distance transportation, braking for a long period of time will lead to wheel heating. If the brake can’t be cooled sufficiently, it will cause reduction or even failure of braking effect. It will also reduce the service life of wheel hub, axle, and tire.
