The fence semi trailer has the advantages of strong specialization, large loading capacity, fast transportation, convenient disassembly, wide use, and low investment cost. Driven by social and economic factors such as energy-saving and environmental protection, it has been rapidly developed and widely used and has become the main equipment of road transportation. However, the fence semi trailers of many informal manufacturers are shoddy, it is difficult for users to get due guarantee in quality and service, and the safety of vehicle operation is difficult to guarantee. With the development of science and technology, the society, the progress of the fence semi trailer is facing the challenges of technological upgrading and other transportation methods in the market.
Here is the content list:
1.What are the technical characteristics of the fence semi trailer?
2.How did the fence semi trailer develop?
1. The model of the fence semi trailer and the fence structure design process is combined with the user's cargo category, rationally designed to fully reduce the weight of the fence semi trailer under load conditions, the structure is simple and suitable, and the disassembly is convenient, reducing investment costs for users and creating more profits value.
2. Frame: the fence semi trailer adopts a space frame structure formed by welding longitudinal beams and integral through-type beams. The fence semi trailer can balance the strength, rigidity, and toughness of the frame, with strong bearing capacity and no permanent deformation.
3. The fence semi trailer’ frame is of a beam-through structure, and the longitudinal beam is of a straight or gooseneck type. The height of the webs ranges from 400 to 500, the longitudinal beams are welded by automatic submerged arc welding, the frame is shot blasted, and the cross beams penetrate the longitudinal beams and weld the whole.
4. Suspension system: the fence semi trailer adopts a new type of suspension system, which has high strength and strong impact resistance; a load of each axle is balanced, and the system tie rod angle is reasonably designed, which reduces the tires of the fence semi trailer during frequent turbulence. The frictional slip distance with the ground can effectively reduce tire wear. At the same time, the tie rod can be adjusted and the wheelbase can be adjusted to effectively avoid the phenomenon of partial running-in and gnawing of the tire.
The rapid development of fence semi trailers began at the beginning of this century, especially around 2008. With the increase of the country's efforts to control overweight, the transportation market's demand for wheel quantified models has become more urgent. At the same time, the national inspection agency's inspection standards for van semi-trailers are further clarified: "The top is closed and cannot be opened" and "No more than two side doors are allowed on the side." The advantages of van semi-trailers are gone. The fence semi trailer is 2~3L lighter than the van-type semi-trailer, so the fence semi trailer is gradually replacing the van-type semi-trailer in some fields, such as the transportation of coal transportation, agricultural and sideline products, and other light foam goods. Fence semi trailers are developing rapidly due to their flexibility and full-featured features, especially the rise of many special cargoes such as small batches and express delivery, and the number of goods transported by fence semi trailers has been continuously increasing. In 2016, the output of fence semi trailers was about 190,195, which was double that of 2015. The growth rate was extremely fast, and it also had an absolute advantage in the overall number of semi-trailers.
It is the responsibility of each manufacturer to produce fence semi trailer that meets the standards, to ensure the healthy development of the fence semi trailer market. Qingdao Feudor International Trade Co., Ltd. conducts many tests on fence semi trailer before they leave the factory, and the quality qualification rate is guaranteed.
