Classification of semi-trailer: Warehouse grate semi-trailer

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 permanent 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.
