How many meters can low plate trailer be licensed?

Low flat semi-trailer is a type of vehicle commonly used in the domestic logistics transportation industry, which is usually used for the transportation of heavy vehicles, rail vehicles, mining machinery, forestry machinery, construction machinery and other heavy goods that cannot be disassembled.

Low plate semi-trailer generally adopts concave beam frame in structure, that is, the front section is gooseneck, the middle section is the cargo platform, and the rear section is the wheel frame. There is no fence plate around. When loading and unloading, the mechanical equipment is moved from the rear wheel frame or the wheel is removed, and then the mechanical equipment is fixed on the semi-trailer.

In March 2020, the Ministry of Transport issued an announcement, redefining the technical specifications of low plate semi-trailer.

In terms of the outer size limit, the original standard of the special semi-trailer for low flat plate requires length ≤13.75m, width ≤3m, height ≤4m, and the new requirement will put the width to 3.4m;

In terms of quality parameters, the original standard requires that the quality of the three-axis low flat plate is less than or equal to 10t, and the new requirement is that the three-axis is more than 42t and the five-axis is more than or equal to 55t. Compared with other types of semitrailers, the maximum loading capacity of low plate semitrailers is 140 square meters, much higher than the volume of standard van semitrailers, equivalent to the total loading capacity of the front car + the rear car with middle axle.

But the new rules do not change the definition of what a low-slab semitrailer is used to transport "unremovable" large objects.

In terms of its own advantages, low flat semi-trailer has low center of gravity, good stability and safety, and strong ability to transport ultra-high cargo and pass height limit obstacles.

It is worth noting that there are particularities in the application field of low plate semi-trailer, and the accessories installed there are certain differences with ordinary semi-trailer.

Take, for example, the low flatbed trailer axles produced by DARO Group. This axle is obviously less than other trailer axles in height off the ground, which is convenient to reduce the center of gravity of the vehicle, increase the transportation stability, but also to provide convenience for the loading and unloading of goods, and the passage of vehicles in high upper limit sections can be enhanced accordingly;

In addition, on the wall thickness of the shaft tube, it can be intuitively seen from the below horizontal screenshot that the wall thickness of the low flat plate hanging axle is significantly higher than that of other axles. The higher the thickness, the higher the strength, the stronger the corresponding load-bearing performance, and the higher the transportation safety of heavy machinery.

In addition, the low flat trailer axle accessories, such as brake drums, brake pads, bearings, bolts, etc., are also special for heavy-duty semi-trailer, strength, toughness, wear resistance and other indicators are higher.

After the update of Technical Specification for Low plate semi-trailer, opinions on low plate trailer in the market are mixed.

1, the owners of the opposition believe that the existence of large pallet car has seriously affected the freight environment, resulting in the current freight only decreased phenomenon, is not conducive to the long-term interests of the owners.

17.5 and 13.75 big plate car in accordance with the requirements can only transport not disassembled large goods, but many owners in the interests of the drive to use them to transport general goods, which is a kind of impact for those who run the transport owners and standardized transportation environment, to strictly implement a more than four penalties, and the national law enforcement unified efforts, otherwise it is difficult to solve.

2. The owners who support it believe that the existence history of low flat trailer is not short. After years of development, it has achieved ecological balance with standardized trailer. They say the main reason for the drop in freight rates is the economic environment. Even if large trucks are not allowed to transport ordinary goods, they will only eventually lead to more 13m new cars flooding the market, which will do little to ease the pressure on freight.

In fact, objectively, the technical specifications and vehicle related qualifications of low plate semi-trailer are clearly marked that its use is used for and can only be used for the transportation of non-disassembled goods, that is to say, it is illegal to use this type of vehicle to engage in general goods such as zero-load and Lvtong, but the current relevant governance standards are not unified, governance is not strict, but this is a kind of industry chaos. Disrupted the development of the logistics transportation market, and the country advocates the standardization, standardization, closed transportation is contrary to, once the relevant departments invest in governance, a lot of vehicles or will therefore idle down, the impact on the owners is also very large, it is recommended that the owners or to put in a long-term view, follow the law of industry development.
