Fence semi trailer

The semi-trailer with fence structure is used in the loading part of the warehouse semi-trailer. It is mainly used for transportation of agricultural by-products and other light bubble goods. 1. The design process of vehicle type and fence structure combines with the types of goods of users, so that the weight of carriage can be reduced sufficiently under the condition of load, the structure is simple and applicable, and the disassembly is convenient, so as to reduce the investment cost for users and create more profit value. 2. Frame: Spatial frame structure composed of longitudinal beam and integral through-beam. It can balance the strength, stiffness and toughness of the frame, and has strong bearing capacity without permanent deformation. 3. Series of grille semi-trailer frames are beam-through structures, and the longitudinal beams are straight or gooseneck. The web height ranges from 400 to 500. The longitudinal beam is welded by automatic submerged arc welding. The frame is shot blasting. The cross beam penetrates the longitudinal beam and welds the whole body. 4. Suspension system: adopt new suspension system with high strength and strong impact resistance; balance axle load, reasonable design of system tie rod angle, reduce friction and slip distance between tire and ground during frequent bump operation, effectively reduce tire wear, at the same time adjustable tie rod, adjustable wheelbase, effectively avoid tyre eccentric grinding and gnawing wheel phenomenon.

Container semi-trailer:

Container semi-trailer is a semi-trailer with container structure. Mainly used in ships, ports, routes, highways, transfer stations, bridges, tunnels, multi-modal transport logistics system. 1. It is specially used for the transportation of various containers. It can be used repeatedly for a long time and has enough strength. 2. Container transshipment of goods can be directly loaded in the shipper's warehouse and unloaded in the consignee's warehouse. It is not necessary to take the goods out of the box and replace them when changing the vehicle or ship halfway. 3. It can be quickly loaded and unloaded, and can be directly and conveniently transferred from one transport to another. 4. Easy to fill and unload cargo to meet customer's personalized needs. According to customer needs, tooling assurance, stable quality, reliable performance. Container semi-trailer is a special transport trailer for carrying containers. In the early stage of container transportation development, because the container load is small and the quantity is small, it is usually carried by ordinary trucks. Since the 1960s, with the rapid development of container transportation, many countries have developed specialized vehicles to transport containers. The size of the loading part of container trailer is determined according to the standard container size, and a torsion lock device for fixing the container is installed at the corresponding four corners of the bottom of the container. A special transport trailer for carrying containers. The four corners of the loading part are provided with a twisting lock device for fixing the container. Usually semi-hanging type, full-hanging type and double-hanging type are adopted, and half-hanging type is the most common type. Semi-trailer can be divided into two types: flat platform and skeleton. The former can also be used to transport Ordinary large and large goods. The latter has no platform, and the container is loaded on the skeleton of the chassis. The torsion lock device is fixed to the strength component of the semi-trailer.
