Ministry of Transportation: Upcoming Hanging Transport Technology Standards

China's Ministry of Transport selected 10 provinces and cities in China to carry out the pilot work of dumping and transport, which was officially launched at the end of 2010. In order to cooperate with the promotion of the hang-and-drop transport pilot project, the Ministry of Communications has proposed research and development plans for relevant standards and hopes to improve the suspension and transport development by improving the standard system of suspension and transport technology. According to reports, the Ministry of Communications recently launched the "Standard Guideline for Road Drop Loading and Transportation," "Technical Requirements for Drop-and-Hold Transport Vehicles," "Technical Conditions for Van Trailers," and "Development and Revision of Cargo Trailer Series". jobs.

At present, the development of China's drop-and-hook transport is lagging, and the ratio of towing to loading is low. Road freight transport is still dominated by ordinary single-trucks or a tractor towing a semi-trailer, which is incompatible with the requirements of energy-saving emission reduction and the development of modern logistics. The reason for this is that the basic technical work of drop-and-hook transportation has not been carried out in depth. This is an important factor.

China's road freight is dominated by common single-trucks. According to experts participating in the formulation of relevant standards, in 2009, China had a total of 9.07 million cargo trucks, but only 290,000 tractors and only 330,000 trailers, accounting for only 3.2% and 3.6% respectively. The ratio of the number of tractors and trailers is only 1:1.14. The number of tractors and trailers is small, and the ratio of trailers to trailers is low. Compared with the level of development of suspension of transport by developed countries, the gap is very obvious.

The dumping and transportation must be "flipped up", and the combination of tractors and trailers must be frequently de-coupled, which imposes high demands on the standardization of vehicles. At present, the models of tractors and trailers in China are numerous and complicated, and the matching between tractors and trailers lacks technical standards. Some transport companies report that they often appear to be “unable to hang and can't be towed”, which restricts the promotion of large-scale production in an objective manner. Hanging operation.

Li Yongfu, chief engineer of the Automotive Research Center of the Institute of Highway Research of the Ministry of Communications, told reporters that in terms of vehicle technical standards, the United States and Europe have established perfect suspension and transportation standards, including requirements for tractors and trailers, and tractors. The combination of trailers and even connecting parts all have a uniform specification.

In China, although there are production standards for tractors and trailers, there are no specific requirements for how tractors and trailers are connected and combined. There is no uniform specification for the connection method and connection components between the tractor and the trailer. The mismatch between the tractor and the trailer cannot effectively improve the operation quality and overall efficiency. The specific issues of these technical links have restricted the rapid development of suspension and transportation.

Ensure that the towing operation is simple and easy The Ministry of Communications and other five ministries and commissions jointly issued the "Notice on Promoting the Development of Road Cars Loading and Unloading Transportation" issued by the end of 2009. It is proposed to promote the standardization of equipment for the suspension and transport of transport vehicles and to organize the development of the connection of tractors and trailers. Relevant technical standards will guide manufacturing companies to strictly implement national standards for the production of tractors and trailers.
