Semi trailer is the main vehicle in the domestic road transportation industry. With the characteristics of high transportation efficiency and low transportation cost, it plays an important role in promoting the form of logistics organization. With the continuous development of vehicle technology, do you know what direction semi-trailer will develop in the future?

1. Lightweight.

With the continuous tightening of overload control efforts of relevant departments, long-distance semi-trailer transportation tends to standard load transportation. Under the condition of a certain gross vehicle weight limit, the lighter the weight of the semi-trailer, it means that more weight space can be reserved for loading goods. For car owners, they can reasonably earn higher freight within the scope of standard load.

Market demand drives production. In order to realize the lightweight of trailers, many trailer manufacturers have come up with many methods, such as replacing traditional steel with aluminum alloy, drilling special-shaped holes on the girder, changing double tires to large single tires, configuring air suspension or lightweight leaf spring / axle, etc. taking Darong lightweight axle as an example, each axle can lose about 15% of the weight of the traditional axle, which can effectively reduce the weight of the trailer itself, Increasing the selection range of goods for car owners can also reduce fuel consumption, energy conservation and environmental protection.

However, we also need to pay attention to that the premise of lightweight must be safety. As a means of heavy cargo transportation, semi-trailer must ensure load-bearing and reliability. If we get rid of the reality and simply pursue "lightweight", the gain is not worth the loss.

2. Standardization.

The introduction and implementation of gb1589-2016 "outer dimensions, axle loads and mass limits of automobiles, trailers and automobile trains" and gb7258-2017 "national standard for safety technical conditions of motor vehicles" have made clear provisions on the outer dimensions, load capacity and chassis configuration of semi-trailer. After the buffer period of the new regulations, vehicles that do not meet the requirements may not be licensed, driven on the road or pass the annual examination. To some extent, this means that the transportation of semi-trailer will be more standardized in the future, and those semi-trailer with super length, super width and overweight may withdraw from the stage of history.

3. High efficiency.

The rapid development of the logistics and transportation industry puts forward higher requirements for the transportation efficiency of vehicles. Whether logistics companies or individual retail investors, the driving mileage of their vehicles is increasing. 150000-200000 kilometers a year is common. For those vehicles, the annual driving mileage is often longer, which can basically reach more than 300000 kilometers. This requires that the maintenance mileage of the vehicle, especially the maintenance mileage of the axle and wheel end, must be improved. The maintenance free axle can just meet this demand.

However, maintenance free ≠ no maintenance, even if the maintenance free axle, the owner can not completely let go, and the daily inspection is still very necessary.

4. Intelligent.

Intellectualization mainly refers to some electronic and automatic technologies, such as tilt alarm, bounce control, anti rollover system, anti lock braking system, remote control, brake pad wear prompt, maintenance prompt, tire pressure monitoring, etc. it is of great significance for vehicle safety, driving comfort, operation efficiency, remote management, energy conservation and consumption reduction.

5. Specialization.

For a long time in the past, many semi trailers drove on the road with goods inconsistent with their own operating conditions, such as the transportation of less than carload goods by low flat trailer, liquid goods by rail car, frozen goods by warehouse truck, etc., which not only affected the quality of goods, but also easily disturbed the market order and was not conducive to transportation safety. With the improvement and promulgation of relevant laws and regulations, the industry pays more and more attention to the special use of special vehicles, and matches different goods according to different vehicle uses.

It is worth noting that the exclusive use of special vehicles to a certain extent means that semi trailers in different application fields need to be equipped with accessories of different specifications and requirements.

For example, the axles under Darong group are suitable for different types of vehicles: the disc axle is suitable for three-axis fence, transportation of valuable goods / precision instruments, transportation of dangerous chemicals and other vehicles with high requirements for transportation stability and cargo loss rate; Drum axle is suitable for heavy goods and all kinds of ordinary goods transportation vehicles; German style vehicle bridge is mainly applicable to long-distance cargo transportation, cold chain transportation, express transportation and other vehicles with high requirements for transportation timeliness and maintenance cycle; Low flat axle is mainly used for low flat semi-trailer and car transport vehicles; Three line six axle axle axle is mainly used for large cargo transportation or large cargo transportation vehicles; Special axle is mainly applicable to agricultural vehicles.

For axles with special requirements and sizes, Darong group can provide customized services to fully meet the use needs of different users.
