Low flat trailer is a specialized vehicle for transporting heavy vehicles, rail vehicles, construction machinery, highway construction equipment, large tank bodies, power station equipment, and other types of non detachable large goods. Its structure is generally designed as concave beam, flat plate, and tire exposed, and there are no guardrails around the body to facilitate the loading, unloading, and fixation of goods.

Compared to other models, low flatbed trailers have a larger transportation weight and higher requirements for transportation stability, passability, and safety. When selecting accessories, such models often have higher requirements. So, can a low flatbed trailer use a regular trailer rear axle?

Before answering this question, let's compare the differences between a low flat axle and a regular axle.

The wheel ends of low flat axle are generally relatively exquisite and compact, and the diameter of the brake drum is smaller than that of a regular axle:

This design makes the ground clearance height of the low flat axle lower than that of the ordinary axle, which can to some extent reduce the center of gravity of the vehicle, make cargo loading and unloading more convenient, and improve the stability of the vehicle during driving. Especially when vehicles transport large goods on roads with height limits, a lower center of gravity often means higher trafficability.

Although the raw material used for the low flat axle is also 20Mn2 seamless steel pipe, the selected steel pipe wall thickness is higher than that of the ordinary axle:

This thickness difference can be completely observed by the naked eye, and this design can to some extent ensure the load-bearing capacity of the low flat axle, so as to provide good and stable support when transporting large goods. In addition, not only the axle beams, but also the wheels, brake drums, brake pads, and other components used for low flat trailer axles are designed for heavy-duty use. Whether it is strength, toughness, or wear resistance, they can fully meet the standards, providing a solid foundation for the transportation of low flat trailer.

From the above content, we know that there are still differences between low flat axle and ordinary axle. Their exterior and internal design are tailored for low flat trailer transportation, which is more in line with the transportation needs of low flat trailer.

Of course, there are many low flatbed axles in the market, with varying quality. How to choose them is also a technology. It is recommended that car owners try to choose products that have entered the market earlier. On the one hand, such products have undergone the baptism of the market, and their quality and performance have been verified; On the other hand, these manufacturers have accumulated years of production experience and their strength is still trustworthy. Of course, if conditions permit, it is still recommended that car owners visit the axle factory on site. Whether it is technology, craftsmanship, scale, and strength, face-to-face inspection can also make false propaganda nowhere to hide.
