The development of Expressway accelerates the process of transportation integration and greatly increases people's travel choice and mobility. For the semi-trailer, taking the expressway can greatly improve the transportation efficiency, shorten the transportation time, increase the transportation benefit, and is conducive to the operation safety to a certain extent. So, how do you charge for driving at high speed on a semi-trailer? What is the charging standard?

Before January 1, 2020, the high-speed semi-trailer will be charged according to the weight, based on the total weight of vehicles and goods weighed at the toll station. The charging amount of vehicles with different tonnage is different. More loading and more charging, less loading and less charging.

From January 1, 2020, the high-speed charging of semi-trailer will be changed to axle charging, that is, it will be charged according to the vehicle model, and the toll will be calculated according to the number of vehicle axles. The vehicle model with the same number of axles will be charged according to the same standard no matter how much goods are loaded or how little goods are loaded.

Among them, two axle trucks with a length of less than 6 meters and a total mass of less than 4.5 tons are classified as class 1 trucks; Trucks with a length of more than or equal to 6 meters or a total mass of more than or equal to 4.5 tons are classified as class 2 trucks; Three to six axle freight cars correspond to categories 3, 4, 5 and 6 respectively.

At the same time, the national highway toll station will carry out non-stop weighing and detection for freight vehicles at the entrance, and vehicles exceeding the limit and overloading are not allowed to enter the highway. In addition to judging from the total mass of the vehicle, it is also judged from the overall dimension of the vehicle: if the total height exceeds 4m from the ground, the total width exceeds 2.55m or the total length exceeds 18.1m, it will be deemed as exceeding the limit.

High speed axle charging on semi-trailer has a subversive impact on the freight industry. The blue light truck that once had transportation advantages has gradually returned to the urban distribution logistics market, and some models with large tonnage and few axles have gradually developed. Basic choice for users running heavy goods 6 × 4. Users who mainly sell goods with light weight can choose 4 × 2 tractor.

In addition, domestic semi-trailer manufacturers and accessories enterprises also began to make a big fuss about lightweight, because for users, under the condition of compliance, the lighter the self weight of the vehicle, the more goods can be loaded and the operating income can be increased. Coupled with the continuous tightening of overload control, lightweight products will be more and more popular.

The lightweight trailer bridge produced by Shandong Darong group is in line with this industry trend. In terms of raw materials, Darong axle has selected high-strength alloy seamless steel pipes with reliable strength and lighter weight. Through 1300 ℃ integrated hot rolling, one-time cold square pushing, 865 ℃ medium frequency quenching, 480 ℃ shaft tempering and thermal insulation, CNC treatment, shot blasting, on-line straightening, precision grinding and other processes, the strength, toughness, ductility, wear resistance and other comprehensive mechanical properties of raw materials are fully stimulated, At the same time, the weight of the finished product is successfully reduced, which is about 15% less than the weight of the traditional axle, which plays a great role in reducing the weight of the vehicle.

As a time-honored axle enterprise with 20 years of production experience, as well as the first axle enterprise in Liangshan to mass produce integrated axles, Darong group has always adhered to the high cost performance route and the price is beneficial to users. Over the years, Darong group has established good and stable cooperative relations with many Trailer enterprises, logistics companies, motorcades and retail investors. The axles of Darong group cover disc type, drum type, concave type, low flat plate, three wire six axle and other series, and provide customized services for special models to fully meet the use needs of users.
