Low flatbed semi-trailer
Low flatbed semi-trailers are usually used to transport heavy vehicles (such as tractors, buses, special vehicles, etc.), rail vehicles, mining machinery, forestry machinery, construction machinery (such as excavators, bulldozers, loaders, road pavers, cranes, etc. ) and other heavy loads, the lower the center of gravity, the better the stability and safety, and the greater the ability to transport super high loads and pass overhead obstacles.
Low flatbed semi-trailers usually use a concave beam (or well-type) frame, that is, the front section of the frame is a gooseneck (the traction pin of the front section of the gooseneck is connected to the traction saddle on the tractor, and the rear end of the gooseneck is connected to the semitrailer frame. connected), the middle section is the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including wheels).
When loading mechanical equipment on a low-bed semi-trailer, it is usually loaded from the rear end of the semi-trailer, that is, by moving the mechanical equipment from the rear wheel frame or removing the wheels, and then fixing the mechanical equipment on the semi-trailer. superior.
Features
Low flatbed semi-trailer is also widely used for the transportation of various types of machinery and equipment, large objects, road construction equipment, large tanks, power station equipment and various steels.
low plate
1. The series of low flatbed semi-trailers have flatbed, concave beam and tire exposed structures, and the longitudinal beams are straight or gooseneck. The frame is stepped, and the longitudinal beam section is I-shaped, which has the characteristics of high rigidity and high strength.
frame pallet
2. The main plane of the frame and platform is low, which ensures the stability of transportation and is suitable for carrying all kinds of construction machinery, large-scale equipment and steel.
Three-axis balance
3. The three-axis balance type, double-axis balance type or rigid suspension is adopted, and a mass balance block is installed between the front and rear leaf springs, which can make the deflection of the front and rear leaf springs change in an equal amount, so that the front and rear axles are balanced in force, etc.;
4. The low-bed semi-trailer series products are suitable for the transportation of various kinds of mechanical equipment, large objects, highway construction equipment, large tanks, power station equipment and various steels. They are widely used, efficient and fast. The whole vehicle adopts advanced computer-aided design software, and the optimization design is flexible and diverse, and the frame bearing surface is designed according to user requirements to meet the transportation of various special goods.
The main types of low-bed semi-trailers are: two-axle high-low-high, two-line four-axle high-low-high, three-axle high-low-high, three-line six-axle high-low-high.
According to the number of axles and the size of the tires, the load of the low-bed semi-trailer is also different. The more the number of axles, the greater the load, and the load range is between 20-150 tons.
