The low efficiency of China's road transport has been criticized, and improving the efficiency of transportation requires multiple departments to work together and make efforts in multiple links. Among them, improving the efficiency of loading and unloading operations is an important part. At the 2013 Wuhan Commercial Vehicle Show, Scania's “Efficient Logistics Operation†physical loading and unloading demonstration demonstrated a legally compliant, low-cost, high-opera- tive, and environmentally-friendly logistics and transportation solution for the audience. The trailer is the "protagonist" of the demonstration. 
Demonstration site, with the white curtain on both sides of the side curtain trailer slowly opened, two kinds of standard specifications of the pallet box placed neatly, the staff will be fixed on the cargo box fastening strips one by one, side curtain There is a forklift loading and unloading operation on both sides. In less than 20 minutes, nearly two-thirds of the containers were unloaded. At the end of the demonstration, the driver adjusted the heights of the front and rear axles by manipulating the air suspension devices of the tractor and the side curtainer. It was only seen that the floor of the cargo box was slightly tilted backwards, and the loading and unloading of the rear compartment was more convenient.
Xu Wei, Strategy Director of Scania China Strategic Research Center, told reporters that due to the side curtain trailers use cords instead of other box materials, and through the rational use of single tires, air suspension, and aluminum alloy materials on each side, the body weight was reduced by 4 Around the ton, effectively increased the legal load, and increased fuel capacity while increasing the carrying capacity. At the same time, the side curtains on both sides and the top curtain can be fully opened, enabling high-efficiency operation modes such as cargo collection and distribution, multi-warehouse touring and loading and unloading of mixed loading and unloading, and more efficient transport between multiple points of supply.
How much can the efficiency of using side curtain trailers be improved? Xu Hao calculated an account: If more 4 tons of cargo loading, at least 20% increase in the carrying capacity. From a time perspective, if it takes 2 hours to unload a car normally and 3 hours to load a car, it takes only half an hour to use the side curtain car, and 1 hour to load and fasten the car. Save up to 70% of the loading and unloading time.
“The reason why the side curtain trailer loads cargo is not only efficient because multiple forklift trucks can be operated simultaneously after the side curtains are deployed. It is more important to use standard pallets to carry out the loading. The loading steps are optimized, and through the mutual combination of pallets, the container volume is increased. The maximum utilization rate. In addition, a reasonable cargo layout also helps to average the axle load, reduce vehicle wear and improve vehicle safety.â€
Our country is vigorously promoting the dumping and transport, and in fact both are conducive to improving transport efficiency. Xu Wei said that the suspension of the transport is to maximize the efficiency of the use of tractors, if the suspension and side curtain trailer combined application, the efficiency of the two can be superimposed.
Policies and regulations to be improved
This reporter learned that the curtain curtain trailer is currently widely used in Europe, about 60% of users will choose, China is only in some coastal cities have applications. Xu Wei introduced to reporters the constraints and resistance of China's promotion of side curtain trailers.
One is worrying about its safety. The cargo fastening straps displayed in this event can firmly hold the cargo in the carriage, effectively avoiding the loss caused by bumpy roads. At present, although China still lacks fixed standards for road cargo, the relevant units are actively drafting draft standards and hope that relevant policies and regulations will be introduced as soon as possible because the cargo fastening zone will not only improve the intact rate of goods transported on roads, but also reduce the safety accidents of vehicles. The risks will make the vehicle safer and more secure.
Second, related policies and regulations lag behind. Now, the outside width of the van has been relaxed to 2.55 meters, but the side curtain is only 2.5 meters. China's pallets are 1.2 meters wide, which means that any inaccurate positioning will result in the inability of the goods to be loaded, and they cannot be quickly loaded with electric forklifts, which directly affects the handling efficiency.
Third, there is no uniform standard for our pallets. U.S. standard, Australian standard, Japanese standard trays are all used. In fact, unified pallet standards can maximize the sharing between the car body and the pallet. There is also the problem of standardization for small-volume goods, such as how much volume the packaged water should be made to fit on standard pallets, and unsuitable size for pallets to be empty, causing waste.
Xu Hao expressed that he hopes that with this demonstration, relevant departments will be given more attention, and China's logistics industry will be promoted to standardize the operational procedures of enterprises, fully mobilize and utilize existing resources, increase the utilization rate of vehicles and equipment, and improve the efficiency of transportation, so as to be truly safe and efficient. ,low cost.
