A tractor loaded with cargo was sent from Qingdao, Shandong Province. After arriving in Weihai, the trailer was dumped and another semi-trailer full of goods was unloaded and returned to Qingdao without stopping. This vehicle transports goods by means of drop-and-hang in the goods distribution centers in Qingdao and Weihai, and is a microcosm of a logistics company in Qingdao to perform drop-and-hook transport.
The pilot project adopting this mode of transportation currently has 69 pilots across the country. It is a pilot project for the Ministry of Transport to promote energy-saving and efficient transportation methods and carry out dumping and transport. In order to promote suspension and transportation throughout the country, the Ministry of Transport recently released the second batch of recommended models for suspension and transportation of highways. It is hoped that standardization will be promoted through the recommendation of suspension models.
A number of products were selected in the list of recommended models
At the beginning of last year, the Ministry of Transport announced the first batch of recommended models for road dumping and transport, with 16 models of 11 car makers short-listed. Compared with the first batch of models, this year, there are 17 tractors with 29 tractor models and 23 semi-trailer companies with 30 semi-trailer models on the list. Not only FAW Jiefang, Dongfeng Commercial Vehicles, China National Heavy Duty Truck and other companies, but also Valin, Guangzhou Automobile Hino, Chery, Dongfeng Liuzhou and other companies selected products, Volvo, Mercedes-Benz and other foreign brand models are also selected for the first time selected models.
According to the person in charge of the Institute of Highway Research of the Ministry of Transport, the production companies reported high enthusiasm and reported more models, and received a total of 144 application models recommended by 45 domestic manufacturers. Most of the recommended models are market-tested flagship products. The recommended models released this time focus on practicality and advancement. The vehicle model selection widely understood the transportation needs of the hang-up transport pilot enterprises and sought the opinions of industry experts. LNG tractors, high-end transport customers are concerned about the air-suspension tractors and semi-trailers, lightweight aluminum alloy semi-trailer list.
It is understood that the models recommended for suspension and transportation have the features of high power configuration and low fuel consumption, ensuring that the transportation vehicles have sufficient power reserve, transportation efficiency and fuel economy; the technical requirements for the vehicle structure size, installation and connection are clear to facilitate the suspension of suspension. Transport operations and driving safety, improve cargo handling efficiency; Optimize vehicle configuration and control environment, Improve traffic safety performance, Reduce over-limit overloaded transport; Vehicle load is heavy, light weight, limited the quality parameters of key components, guide the vehicle to standardization Development of light weight.
Guide the standardization of vehicles with efficient transportation demand
Drop-and-hook transport is a form of efficient transport. Judging from foreign experience, the standardization of vehicle models is a necessary condition for the realization of the suspension and transportation. In developed countries such as Europe, the United States and Japan, dumping and transport has become the mainstream mode of transport. Semi-trailer trucks consisting of tow tractor trailers account for nearly 80% of the total transport volume. In China, the advanced transport mode of slinging and hanging transportation has been developing slowly.
According to Yu Weijiang, head of the vehicle management department of the Department of Road and Transportation of the Ministry of Transport and the head of the expert working team of the recommended models for suspension and transportation, compared with the basic requirements for vehicle suspension and transportation, China’s transport vehicles still have many problems. The tractors and semi-trailer models are numerous and there are more than 800 models of tractors alone.
Among them, the top 10 models only accounted for 18% of the market share; there is no standard specification for the connection and matching of tractors and trailers, and the separate development and production of truck companies and special vehicle companies lack unified design. These problems have caused the tractors and semi-trailers to “pick up and fail to pull†in the process of drop-and-hook transportation, seriously restricting the promotion of large-scale suspension and transportation, especially cross-company and cross-industry suspension and transportation.
In 2005, the Ministry of Transport issued the "Working Rules for Cars and Cars Train Recommended Vehicles", and formulated the "requirements for vehicle suspension and transport recommended models that meet the relevant requirements for the management of operating vehicles and meet the technical requirements for vehicle equipment for suspension and transport." 》 Since then, the National Circular issued by the relevant ministries and commissions has also clearly stated that it is necessary to organize the development and application of relevant technical standards for the application of tractors and trailers, and to guide manufacturers to strictly implement national standards for the production of tractors and trailer.
In order to promote the demonstration project of suspension and transportation, the Ministry of Transport announced two recommended models, and through these recommended models, specific requirements were imposed on the suspension and transportation vehicles.
Promote technology upgrades to improve product quality
Some commercial vehicle manufacturers are more active in recommending the transport of dumped and transported vehicles. The relevant responsible persons of CNHTC and Shaanxi Auto have stated that they are involved in the suspension and transport of transport models, which is beneficial to product standardization and promotion of corporate reputation. Cai Dong, general manager of China National Heavy Duty Truck Group believes that the suspension of transport recommended models to guide vehicle manufacturing companies pay more attention to the development needs of the transport market and vehicle standardization, and promote the comprehensive upgrading of modern road transport technology and equipment.
As a production enterprise, it should actively participate in the formulation of relevant standards and standards and the application of the recommended models for road dumping and transport; in the production process, it should further improve quality control and production consistency management, and carefully follow up the follow-up work on the models recommended for dumping and transport. A commercial vehicle company believes that the Ministry of Transport has certain requirements on product quality and technology when screening vehicles, and entering the list of recommended models for suspension and transportation will help improve product quality and technology.
