Speaking of semi-trailer transportation, many people think it is a business that can make a lot of money. The freight is often more than 10000, which is much better than migrant workers. Therefore, more and more freight forwarders want to transfer from the original ordinary freight to semi-trailer transportation. So, what kind of driver's license do you need to drive a semi-trailer? Can the original B2 driver's license continue to be used?

The answer is No. The semi-trailer is a tractor, which is different from the ordinary freight vehicle. It can only be driven with A2 driver's license.

1. A1: the permitted driving models are large buses with a body of more than six meters and more than 20 passengers, A3 city buses, B1 medium buses and B2 large trucks.

2. A2: the permitted driving model is tractor, including full trailer and semi-trailer. Note that even if you have an A1 driver's license, you are not allowed to drive a tractor, so the tractor trailer can only be driven by the owner of an A2 driver's license. A2 is also allowed to drive B1 medium-sized passenger cars and B2 large trucks.

3. A3: city buses are allowed to drive. Although some city buses are longer than buses, A3 driver's license does not allow driving large buses, nor does it allow driving B1 or B2 models. In addition to urban public transportation, A3 is also allowed to drive C1 small cars.

4. B1: the quasi driving model is a medium-sized bus with a body length of less than six meters and a seating capacity of 10-19 people. In addition, you can also drive C1 small cars and m-wheeled self-propelled mechanical vehicles. It should be noted that B2 is not included in the quasi driving model of B1 driver's license.

5. B2: the permitted driving models are large trucks or large, heavy and medium-sized special operation vehicles, C1 small cars and m-wheeled self-propelled mechanical vehicles.

It can be seen that although trucks and trailers belong to transport vehicles, if you want to change from driving trucks to driving trailers, you need to apply for an additional driving license first.

As for how much money a semi-trailer driver can earn in a month, it depends on the average level of the owner's area, whether the owner's supply of goods is stable and whether he can often have business. It also depends on the owner's usual attendance rate, the distance of the route, whether he often doesn't care about going home in black or white, or whether he can have a fixed time to go home every month, In addition, it also depends on whether to run alone or for others. What is the profit composition when running for others? The income of those with complete qualifications, high driving age, rich experience and strong handling ability is also relatively higher.

Generally, the general treatment for A2 drivers is about 10000 yuan a month. When the supply of goods is stable, the monthly income is at least about 10000, or tens of thousands. In addition to the basic salary, some car owners will pay a certain proportion of transportation profits separately according to the attendance rate or transportation efficiency. Of course, there are seven or eight thousand or even fewer cases in a month, which also need specific analysis of specific problems. In addition, semi-trailer transportation has high requirements for contacts, resources and experience, so it needs to be analyzed and considered calmly and comprehensively.

To improve operational efficiency, the procurement of semi-trailer parts is also a knowledge. If we can select those products with excellent and reliable performance, quality and affordable price from a wide variety of products in the market, it is very key to reduce the cost of comprehensive vehicles.

Take the axle as an example. At present, the most widely used type of axle in China is American. Its axle adopts an integrated axle body, which is different from the welded axle body of three joints, and has stronger heavy load performance. In addition, the axle head design is strengthened, and a more regular shape is adopted to increase the thickness and strength of the connecting part with the bearing, so as to further provide guarantee for the improvement of bearing capacity.

With the development of the domestic axle industry for many years, the production process of this integrated axle is no longer monopolized in the hands of first-line brands. Many time-honored axle enterprises have also mastered this technology. For example, Shandong Darong group is one of the first enterprises to mass produce integrated axles, including disc axle, drum axle, low flat axle, three-line six axle axle Integrated axle bodies are widely used in special axles, and on this basis, improvements have been made according to the actual needs of domestic users, such as lightweight and long maintenance cycle.

More importantly, since its establishment 20 years ago, Darong group has always adhered to the cost-effective route, which can provide users with more realistic and affordable price choices. At present, the cooperative customers of Darong group have widely covered Trailer enterprises, logistics companies, fleets, retail investors, axles / axles / accessories, with an annual demand of more than 170000 pieces. The accessories are universal and easy to maintain, so that the majority of car owners can use more reliable products with less money.
