13 meter double door high bar semi-trailer with stable price and sharp design

Description :

　　Around 2021, with the increasing national efforts to control overloading, the demand for lightweight vehicle models in the transportation market has become more urgent. The curb weight of the compartment semi-trailer is 2-3 tons lighter than that of the box semi-trailer, especially with the promotion and application of high-strength steel for automobiles, which greatly reduces the curb weight of the compartment semi-trailer. In general, the self weight of the 13m compartment grate is 6-6.5t, which is significantly better than that of the box semi-trailer. At the same time, the relevant national departments have further clarified the testing standards for the box semi-trailer: "The top is closed and cannot be opened" and "There are no more than two double doors allowed on the side". The advantage of convenient use of the box semi-trailer is completely lost.

　　Therefore, in some fields, it is gradually replacing box type semi trailers. Warehouse rack semi trailers have developed rapidly due to their flexibility, versatility, and complete functions. Their types and structures are also gradually improving, and they have an advantage in the overall number of semi trailers. At present, the silo semi-trailer has become the main equipment for road transportation due to its advantages, such as strong customization, large loading capacity, fast transportation, easy disassembly, wide application, and low investment cost. With the promotion of social and economic factors such as energy conservation and environmental protection, it has developed rapidly and been widely used. In order to adapt to different types of cargo transportation, the warehouse style semi-trailer has evolved from a single door opening method to multiple door opening methods, such as single-layer and double-layer warehouse grilles, long lock bar and short lock bar warehouse grilles, and other vehicle models. Single layer and double layer grille semi trailers are quite common and are also the earliest grille structures. The height from the bottom plate of a single-layer semi-trailer to the top of the grille generally does not exceed 1800mm, making the grille easier to disassemble; The height from the bottom plate of a double decker semi-trailer to the top of the grille is generally above 1800mm, and the strength of the grille is higher. These two types of warehouse semi trailers are mainly used for long-distance transportation, such as agricultural and sideline products, steel, and large volume light foam goods.

　　A semi-trailer designed with a fence structure for the cargo area of a warehouse style semi-trailer. Mainly used for the transportation of agricultural and sideline products and other light foam goods. 1. The design process of the vehicle model and fence structure is combined with the user's cargo category, and is reasonably designed to fully reduce the weight of the carriage under load conditions. The structure is simple and applicable, easy to disassemble, and reduces investment costs for users, creating more profit value. 2. Frame: A spatial frame structure composed of longitudinal beams and integral through type transverse beams welded together. It can balance the strength, stiffness, and toughness of the frame, with strong load-bearing capacity and no deformation. 3. The series of warehouse rack semi-trailer frames are all of the through beam structure, with longitudinal beams of the straight or goose neck type. The web height ranges from 400 to 500, the longitudinal beam is welded by automatic submerged arc welding, the frame is shot blasted, and the crossbeam penetrates the longitudinal beam and is welded as a whole. 4. Suspension system: adopting a new type of suspension system with high strength and strong impact resistance; The load of each axle is balanced, and the angle of the system pull rod is designed reasonably. During frequent bumps, the friction and sliding distance between the tire and the ground are reduced, effectively reducing tire wear. At the same time, the pull rod can be adjusted to adjust the wheelbase, effectively avoiding the phenomenon of tire running in and biting.

　　The warehouse semi-trailer is developed based on the early coal transportation box semi-trailer. At that time, the side of the coal transportation box semi-trailer was fully open and had a long locking rod structure. Later, due to changes in the technical requirements of the country for box semi-trailer, the weight of the box truck was relatively large, and the top of the warehouse semi-trailer was open, making it easy to load mechanical equipment. After the inner side of the side warehouse was nailed with canvas, the surrounding area was basically closed, which had the function of a box truck. When the side doors were fully opened, the door opening size was relatively large to meet the unloading needs of construction machinery such as forklifts. The box coal transportation semi-trailer was gradually replaced by the long locking rod warehouse semi-trailer. When the length of a semi-trailer with a long lock bar is generally over 11m, there are 3 pairs of doors on each side. Compared with long lock bars, short lock bar semi trailers have no top edge and shorter lock bars, making them relatively lighter in weight. The interior of its side grille can also be nailed with canvas, but due to the lack of an upper bumper, the anti swelling ability of its grille is relatively poor compared to the long lock rod structure. In terms of size, the length of a short lock bar semi-trailer is generally 13m, and the height from the bottom plate to the top of the warehouse rack is generally not more than 1800mm. This type of warehouse rack semi-trailer can not only transport coal and sand and gravel, but also carry out long-distance logistics and general cargo transportation.
