Low flatbed semi-trailers are commonly used to transport heavy vehicles (such as tractors, buses, specialized vehicles, etc.), rail vehicles, mining machinery, forestry machinery, engineering machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.), and other heavy-duty goods. The lower the center of gravity, the better the stability and safety, and the stronger the ability to transport ultra-high cargo and pass overhead obstacles.
1, Structure
Low flatbed semi-trailers usually adopt a concave beam (or well shaped) frame, with the front section of the frame being 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 semi-trailer frame), the middle section is the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including the wheels).
2, Loading
When loading mechanical equipment onto a low flatbed semi-trailer, it is usually done from the rear end of the semi-trailer by moving the mechanical equipment from the rear wheel frame or removing the wheels, and then fixing the mechanical equipment onto the semi-trailer.
3, Product features
Low flatbed semi-trailers are also widely used for transporting goods, suitable for various types of mechanical equipment, large objects, highway construction equipment, large tank bodies, power station equipment, and various types of steel.
Low flatbed
The series of low flatbed semi-trailers have flat, concave beam, and tire exposed structures, and the longitudinal beam adopts a flat or gooseneck type. Its frame is stepped and the longitudinal beam section is I-shaped, with high stiffness and strength.
Frame cargo platform
The main plane of the frame cargo platform is low, ensuring smooth transportation and suitable for transporting various types of construction machinery, large equipment, and steel.
Three axis balanced type
Adopting three-axis balance, double axis balance, or rigid suspension, a mass balance block is installed between the front and rear steel plate springs, which can make the deflection of the front and rear steel plate springs change equally, and balance the force on the front and rear axles;
The low flatbed semi-trailer series products are suitable for the transportation of various types of mechanical equipment, large objects, highway construction equipment, large tank bodies, power station equipment, and various types of steel. They have a wide range of uses and are efficient and fast. The whole vehicle adopts advanced computer-aided design software for flexible and diverse optimization design, and the frame bearing surface is designed according to user requirements to meet the transportation of various special goods.
4, Type
The main types of low flatbed semi-trailers are: two axle high and low, two line four axle high and low, three axle high and low, and three line six axle high and low.
5, Load capacity
According to the number of axles and tire size, the load capacity of a low flatbed semi-trailer also varies. The more axles there are, the greater the load capacity, ranging from 20 to 150 tons. The maximum weight limit for six axles and above on highways is 49 tons.
6, Technical specifications
The Technical Specification for Low flatbed Semi trailers specifies the general technical requirements for low flatbed semi-trailers, special requirements for low flatbed reinforced semi-trailers, test methods, inspection rules, as well as identification, on-board documents, and storage. This standard applies to the design, production, inspection, and use of low flatbed semi-trailers.
