With the continuous improvement of cargo transportation requirements in all walks of life, the freight industry has more and more subdivided fields, and different transportation fields also put forward different requirements for vehicle types, so the concept of "special vehicles for special use" came into being, such as slag trucks, mixer trucks, refrigerated vehicles, hazardous chemicals transport vehicles, etc.

However, in the actual use process, due to the restrictions of the source of goods, freight, and the number of vehicles and goods, some special vehicles also began to "use one vehicle for multiple purposes" and "cross the border" to pull goods.

1. Low platform semi-trailer

I'm afraid that the most common one of the "special cars are not special" is the low platform semi-trailer, which is what we often call the large platform truck.

According to the announcement, the large plate truck is a special vehicle, which is specially used to transport large and non detachable goods. In the actual transportation process, only the three line six axle semi-trailer is really used for the transportation of large goods. Other low plate semi-trailers, such as 17.5 large plate and 13.75 large plate, are generally used for the transportation of general goods, such as goods dumping, department stores, LCL, household appliances, furniture, Lvtong, express delivery, mechanical equipment, cement Sand and gravel have become their transportation goods. In the words of car owners, they can pull any goods and earn any money.

The width limit of low platform semi-trailer is 3m, and the length is generally more than 13m. Its cargo platform is low and there is no fence around it. Therefore, its loading capacity is very terrible. Other transport vehicles are not competitors at all. Therefore, many owners regard it as the culprit of disrupting the freight market, which is one of the reasons for the continuous decline of freight.

2. Skeleton container semi-trailer

Skeleton semi-trailer is welded by longitudinal beam, cross beam and front and rear end beams. Its bottom is exposed from the top of the body. Generally, it is mainly used to transport containers and is used in logistics systems such as ships, ports, routes, highways, transit stations, bridges and tunnels.

According to the announcement, the maximum length of skeleton semi-trailer can reach 13.95m, so as to better adapt to the standard container length of 45ft on the market, which is 20cm longer than box semi-trailer.

However, in actual use, the extra space given by the laws and regulations failed to meet the market's desire. Containers with extra length, width and height appeared. Under less strict laws and regulations, the loading capacity was increased in violation of regulations.

What's more, the containers in the upper loading part are directly replaced by refrigerated compartments, racks, dump carriages, etc., to transport different kinds of goods. Although this kind of modification looks ingenious, it is actually dangerous and illegal.

3. Vehicle transport semi-trailer

That is to say, the car carrier, as its name implies, is a semi-trailer specially used to transport passenger cars, vans, commercial vehicles, jeeps and other passenger vehicles. Especially after the emergence of the concept of "zero kilometer transportation" for new cars, the market coverage of car carriers is also increasing.

Generally, car carriers can be divided into skeleton type, fully enclosed type and semi enclosed type. In the past, when the supervision was relatively weak, some people, driven by the interests, lengthened or widened the carriages, or changed the single row to double row, so there were "single row", "single cage", "small cage", "two strange", "T cage", "airplane jump", "big strange" and other car nicknames.

With the gradual strengthening of the supervision of the relevant departments on the vehicle transport industry, the illegally modified vehicles have relatively converged. However, the phenomenon of "cross-border" transportation still exists.

4. Refrigerated semi-trailer

In the freight market, cold chain transportation is the envy of ordinary car owners. Its supply of goods is relatively fixed, and a lot of people earn 20000 to 30000 a month. However, with the influx of a large number of new vehicles and the emergence of the epidemic, the cold chain market does not seem to be as popular as before, and some refrigerated vehicles even begin to seize the business of the general goods market.

In particular, retail refrigerated vehicles can't find the source of goods on the return trip, and the owners are unwilling to let the vehicles run empty. Therefore, if they can't find cold chain goods, they will also pick up some ordinary goods. Some refrigerated car owners are willing to reduce the freight to get the order.

In fact, the refrigerated truck transportation of ordinary goods does not meet the requirements of laws and regulations. Although it seems that the refrigerated truck is not much different from the van, according to the Regulations on Road Freight Transportation and Station Management, the refrigerated truck belongs to the "special transportation" category of "using refrigerated and fresh-keeping equipment" for transportation. If its operation certificate is clearly marked with "special transportation of goods (cold storage and fresh-keeping equipment)", it is not allowed to carry out general cargo transportation, otherwise it is likely to face punishment once investigated.

5. Dangerous chemical transport vehicle

The transportation of dangerous chemicals is a special type of transportation, which has certain safety risks. The general review procedures, qualification conditions, transportation supervision and other links are much stricter than the transportation of ordinary goods.

It is rare to see dangerous chemicals transported by trucks, but there is no such thing. So does it meet the requirements of laws and regulations? In fact, laws and regulations have clearly stipulated that:

The tank type special vehicles or special vehicles for the transportation of toxic, infectious and corrosive dangerous goods shall not be used for the transportation of ordinary goods; Other dangerous goods transport vehicles can be used to transport ordinary goods if they meet certain conditions, such as cleaning and disinfection and sterilization of dangerous goods vehicles or after hazard elimination treatment and inspection. Dangerous goods shall not be mixed with ordinary goods for transport.

It can be seen that if the dangerous chemicals transport vehicle meets the corresponding standards, it can also be engaged in general cargo transport.

After seeing these cases of special vehicles "crossing the border" for transportation, many ordinary freight car owners said that they had a headache: there was only one source of goods in the ordinary freight market, ordinary vehicles could not be divided, special vehicles also came to grab, and even reduced the freight for the purpose of getting orders. How can ordinary freight car owners survive?

From a macro perspective, this chaos of "cross-border" transport is also not conducive to the long-term development of the freight market. "One vehicle with multiple uses" may be the immediate demand of transport participants, but it is not the ultimate demand of the freight industry. Perhaps in the actual implementation of laws and regulations, due to the different implementation standards, it provides a hotbed for violations to a certain extent. However, owners should be clear that existence is not equal to rationality. If it is determined that it is an illegal act, it is better not to do it, otherwise once caught, it will not be worth the loss.
