Ordos double-trailer car train pilot operation

The dual-trailer focuses on high efficiency and energy saving, and has advantages in optimizing road transportation, improving transportation efficiency and economy, and promoting high efficiency and low carbon. However, because the double-trailer exceeds the provisions of GB1589 that "the maximum allowable total mass of the vehicle is 49t, the maximum total length does not exceed 16.5m, and the total length of the car train does not exceed 22m", it is an overlong and overweight vehicle, so it has not been legally operated on the road. With the launch of the Ordos double-trailer pilot operation, this regulation may usher in trailer axle reform.

Recently, 18 dual-trailer trains arrived at Dalate Banner in Ordos via G210 line. Get ready for the pilot.

It is understood that this batch of double-trailer car trains adopts the form of 9-axle 6*4 tractor + A trailer + B2 trailer, which meets the National VI emission standard; the traction power is 560 horsepower, and the traction device is 90# traction seat and traction pin. Electronic stability control, 360-degree surround view, blind zone anti-collision and other systems; the vehicle carrying unit is a standard seaborne 20-foot container, with a designed axle load of 8t and a total load mass of 74t. Compared with ordinary trailer combinations, the transport volume of these double-trailer car trains can be increased by 50%, and the transportation unit cost of various comprehensive cargo combinations can be reduced by an average of 34%. At the same time, the unit fuel consumption of transported goods can also be reduced by 10%.

Advantages of double trailers

As a representative of high-efficiency and energy-saving transport models, the advantages of double-trailer vehicles can be simply summarized as more transport, less consumption, and less emissions. The implementation of double-trailer transport can improve the efficiency of multimodal transport logistics, reduce logistics costs, reduce road occupancy, and reduce The total traffic flow and congestion rate of road freight vehicles will be realized as soon as possible to achieve "carbon peaking and carbon neutrality" and speed up the construction of a powerful transportation country.

Looking abroad, double trailers have been put trailer axle into operation in many countries, such as Sweden, Finland, Netherlands, Spain, Australia and so on.

Disadvantages of double trailers

The double-trailer has a long length and a heavy load. It is more difficult to turn or turn around on a narrow road section than an ordinary semi-trailer. This puts forward higher requirements for the technical configuration of the vehicle and the quality and skills of the driver. In addition, most expressway entrances and exits, roundabouts, and curves in China cannot meet the transportation needs of double trailers, and service areas or gas stations cannot provide suitable parking spaces. To realize the popularization of dual-trailer vehicles, it is necessary to fully consider road infrastructure, road network traffic density, personnel safety awareness, driver training and other factors.

Those foreign countries that have put into use double-trailer trucks also have very strict requirements for double-trailer operation. Drivers must have 5 years of truck driving experience and have no accidents for 3 consecutive years. They must receive special training before driving; overtaking is prohibited throughout the driving process. , driving is prohibited in bad weather; the length of the vehicle must be marked on the rear of the vehicle, reflective strips and warning signs must be installed, hydraulic retarder, full vehicle air suspension and disc brakes must be installed, and complete mechanical and electronic auxiliary systems trailer axle must be equipped, such as blind spots Monitoring, adaptive cruise control, electronic stability system, etc.

Reasons for the implementation of double-hanger transportation in China

This also needs to be addressed from the perspective of the environment. my country has a large volume of road transport, heavy energy conservation and emission reduction tasks, and a long way to go to achieve the goal of "double carbon". The contracting parties to the Convention need to promote the integration of domestic models with international models and improve the types of road transport vehicles in our country.
