At present, semi-trailer is the most widely used vehicle in domestic road cargo transportation. Its Trailer bucket can be divided into many types according to different transported goods, such as van type, flat plate, warehouse grid, breast board and so on.

In the early years, "when the motor rings, ten thousand liang of gold" was a common recognition inside and outside the industry. The increasing number of semi-trailer purchases has pushed many brands and manufacturers into the industry, and the market is gradually becoming saturated. The great sales pressure promotes the emergence of various marketing means, and the semi-trailer "trade in" is one of them.

What is "trade in"? Very simple, it is to add the procedures of old cars to the new semi-trailer (or the new semi-trailer). The trailer manufacturer will recycle the user's old trailer to offset the price of some new cars.

There are generally two ways to "trade in" semi trailers:

1. The old trailer is sold to the trailer factory to offset part of the new car price. Users sell all their old trailers to the trailer factory, and the manufacturer converts the old trailer into cash to offset the price of the new trailer. Users only need to pay the price difference. The price of the old Trailer depends on its new and old degree and the performance of various parameters, and it should be determined according to the market situation at that time.

2. The old trailer is sold to the trailer factory. Generally, it is mostly loaded on the trailer, so as to discount and offset part of the new car price. If many parts and components of some users are in good working condition, such as tires and axles, manufacturers can also be required to continue to use these parts and components on new cars, and finally pay the price difference.

According to insiders, at present, the "trade in" of semi-trailer has long been common. Most Trailer enterprises have more or less carried out this promotion business and are more favored by car buyers.

The benefits of "trade in" semi trailers are also obvious:

1. It allows car buyers to buy a new semi-trailer with less money, which saves more money;

2. This kind of "trade in" is basically built in combination with the use conditions of car buyers, which is more suitable for actual use;

3. In the "trade in" of semi-trailer, it is basically the replacement of light body trailer for heavy trailer, with lighter self weight and less charge under the condition of weight charge;

4. For manufacturers, "trade in" eliminates the formalities, and only needs to be produced according to the size of the original formalities, models or user requirements, which is more worry-free.

However, the semi-trailer "trade in" does not meet the requirements of relevant laws and regulations, that is, this "trade in" purchase method is likely to make the owner face punishment.

The main reasons are as follows:

1. According to the provisions on compulsory scrapping standards for motor vehicles, "the owner of motor vehicles shall sell the motor vehicles to the scrapped motor vehicle recycling and dismantling enterprises, which shall register, disassemble and destroy the scrapped motor vehicle recycling and dismantling enterprises according to the provisions, and submit the registration certificate, number plate and driving license of scrapped motor vehicles to the traffic management department of the public security organ for cancellation". Trailer manufacturers are manufacturers and do not have the qualification to recycle scrapped vehicles.

2. If you choose to use the procedure and number plate of an old car in "trade in", it is basically equivalent to a licensed car. Although it saves money when you buy it, there may be many problems in subsequent use. For example, the insurance company refuses to settle the claim for this reason, or is caught by the traffic police and faces the severe punishment of fine, deduction of 12 points and degradation.

3. If the purchase tax is not paid in the process of "exchanging the old for the new", it is a serious act of tax evasion, which violates the law. Once it is found, there is no need to say more about the punishment.

Therefore, the semi-trailer "trade in" is not desirable, and it will be more troublesome in case of problems in the follow-up. Especially for the semi-trailer, which needs to transport heavy goods frequently, the service environment of its parts is generally complex and harsh, and the degree of wear and tear is generally large. Of course, if the old car is basically unused after buying it back, it's another matter. Otherwise, many damages of these workpieces cannot be identified with the naked eye. Unless they are tested by special technology, it is not recommended to directly remove them from the old car and continue to install them on the new car.

Darong heavy industry group is an enterprise specializing in the production of trailer axles. Up to now, it has accumulated 20 years of industry experience. The "one-piece" trailer axle produced by Darong heavy industry group has made great improvement in the anti heavy load performance. The axle head and axle body are ground from a piece of steel, eliminating the steps of connecting the axle head and axle body by welding in the traditional "three-piece" axle, avoiding thermal deformation and improving strength and stability.

Darong's disc axle, drum axle, low flat axle, concave axle, three wire six axle axle axle, special axle and other series are rich, stable and reliable in quality. For many years, it has been widely praised by the market with its ultra-high cost performance.
