　　Where to start with lightweighting of semi-trailer? Detailed content

　　With the comprehensive implementation of toll collection across the country, light-duty semi trailers are receiving increasing attention from drivers. Many netizens are inquiring about the lightweight information of semi trailers. Therefore, we have collected relevant information and consulted semi trailer staff. Let's take a look at where the lightweight of a semi-trailer is.

　　On the basis of selecting lighting, the difference in weights between different models is very large, and only when the selected model says that lightweight is meaningful. For example, when transporting heavy coal in the north, iron powder is usually hung at the entrance of the warehouse instead of being dumped or disposed of in goose necks, as the amount of goose necks and garbage is unacceptable.

　　Shortening the length of a semi-trailer also helps to reduce weight. According to a post by netizen "Yishui Leng", shortening the length of a semi-trailer appropriately can effectively help with weight loss. However, only when it comes to coal, iron, and other heavy-duty semi-trailer trucks, can the body length of the semi-trailer be appropriately shortened. Generally, it is 13 meters long here, but gradually people are starting to make it 12 meters long, and some even 11 meters long, reducing a few hundred pounds is not a problem!

　　It should also be noted that if the body is short, it must be installed high, and the center of gravity of the semi-trailer will inevitably increase, especially in areas with poor road conditions. Attention should also be paid to the national regulations for semi-trailer installation.

　　How to "slim down" a healthy weight loss semi-trailer

　　After determining the specific model, the lightweight of the semi-trailer tracked the execution of each part. The following are the main parts of the semi-trailer.

　　Main beam: made of height steel

　　The main beam is a crucial component of a semi-trailer, and the quality of a semi-trailer largely depends on the beam quality. To alleviate the current situation where the steel used for the main beam of semi-trailer trailers is mainly ordinary steel, manganese steel, height steel, etc., good materials can ensure the load capacity. According to the salesperson in the trailer, the warehouse semi-trailer uses height steel beams that are about 1 ton higher than ordinary beams. Welding height steel requires a rigorous process and is more difficult. When choosing a semi-trailer manufacturer, it is important to choose a cardholder with higher technical skills to ensure the quality of the semi-trailer manufacturer.

　　In addition to using high steel, curved beams are a common "ton" type of beam that is lightweight. Although curved beams are cheaper and lighter than traditional beams, there is a certain gap in degree or weight compared to traditional beams, and semi-trailer manufacturers rarely use this design.

　　Suspension: few leaf spring, air suspension

　　Lightweight spring suspension can lose a lot, such as the use of 4-chip lightweight spring grille semi-trailer, which can reduce to 100 kilograms compared to ordinary springs. By adopting air suspension, the weight reduction effect is more significant. It is reported that compared with ordinary springs, air suspension can reduce about 500 kilograms, but it also eliminates the weight required to match the accessory axle. More expensive, but the price of air suspension is lower for three axle semi trailers at 28000 yuan, while air suspension costs 47000 yuan, making imports even more expensive.

　　The company is a designated production enterprise for special vehicles approved by the Ministry of Industry and Information Technology of China, and is a management enterprise of the National Automobile Announcement Catalog. It has obtained the national manufacturing product quality "CCC" certification, passed the ISO9001:2000 quality management system certification, and has self operated import and export licenses. Its products are exported to Mongolia, Kazakhstan, Russia, Southeast Asia, Africa, South America and other regions. Shandong Liangshan Tiantong Special Vehicle Manufacturing Co., Ltd. is located at the foot of Shuibo Liangshan, the birthplace of the classic Chinese novel "Water Margin" and the production base of Chinese trailers (special vehicles), on the east side of National Highway 220.

　　Refuse to raise dust from soil and debris Intensify the promotion of intelligent and environmentally friendly dump trucks in various regions

　　In addition to industrial emissions and diesel truck standard emissions, construction site dust, especially the transportation of urban construction waste, is also one of the main sources of fine particulate matter (PM2.5) in cities. Although relevant departments in various regions have strict regulations on the collection, transportation, and disposal of waste trucks, there are still phenomena such as illegal dumping, inability to achieve full closure, scattering everywhere, and soil hanging in the carriages.

　　Intelligent environmental protection What is the difference between the new type of dump truck?

　　What is an intelligent and environmentally friendly dump truck? New dump trucks must be equipped with GPS positioning devices and speed limit loading systems. During loading, if the dump truck is too full and the environmental protection cover is not sealed, the vehicle cannot be started. During transportation, if the driver speeds up, the intelligent system will automatically control deceleration.

　　According to Wang Fa, the president of Kunming Waste Industry Association, intelligent waste trucks in Kunming need to be equipped with Beidou vehicle positioning terminals and connected to the Ministry of Transport platform and Kunming Smart City Management Monitoring Platform. In addition to real-time detection of whether the cargo compartment is loaded, whether the roof is sealed, and whether the cargo compartment is lifted, the in vehicle intelligent control system will also supervise whether the dump truck is driving according to the prescribed route and whether there are speed issues. It is equipped with corresponding automatic alarm, automatic speed limit, and remote locking functions.

　　Implementation of promotion policies in multiple provinces and cities The pace of phasing out old car models is accelerating

　　According to reporters from the Special Vehicle Network, there are currently 1631 dump trucks in Fuzhou, Fujian Province, of which 693 are old dump trucks. According to personnel from the Fuzhou Municipal Waste Management Office in Fujian Province, according to the plan, all these old waste trucks in Fuzhou will also be withdrawn from the Fuzhou operating market before July 2018.

　　In addition to Fujian Province, many provinces and cities such as Hubei Province (Wuhan), Henan Province (Zhengzhou), Anhui Province (Hefei), and Tianjin have put the promotion of intelligent and environmentally friendly dump trucks and the elimination of old vehicles on the agenda. Among them, Kunming City in Yunnan Province has advanced the original plan to promote the application of intelligent and environmentally friendly dump trucks in 2018 by half a year, and has decided to promote the use of intelligent and environmentally friendly dump trucks and eliminate existing models within the third ring road of Xishan District in Kunming City from July 1, 2018.

　　In summary, under the concept of "continuously reducing PM2.5 and adhering to the blue sky defense battle", intelligent and environmentally friendly dump trucks are the new trend in the development of dump trucks.
