Quotation for a 2.55-meter-wide semi-trailer with a lightweight disc brake bridge

Description :

　　According to the new regulation GB7258, starting from January 1, 2020, three axle rail type and compartment type semi trailers must be equipped with disc brakes, and dangerous goods transport vehicles must use disc brakes one year in advance. The new regulations have given car companies and truck drivers two years as a buffer, indicating that trailer chassis accessories will become more compliant in the future. In addition, GB7258 also stipulates that in the future, models such as three axle rail type and compartment type semi trailers will use airbag suspension. The use of airbag suspension on semi-trailer can improve the shock absorption effect of the vehicle. In addition, when the vehicle is unloaded, the trailer axle can be raised to reduce the friction between the tires and the ground, lower the fuel consumption of the vehicle, and improve fuel economy. Disc brake airbags will be popularized, and strict implementation of regulations for over limit transportation will make semi-trailer transportation more standardized in the future. Those ultra long and ultra wide semi-trailers will become history in the near future, and semi-trailers in the future will be more compliant. In addition to the overall dimensions of the semi-trailer, the load capacity is more compliant, and the chassis configuration is also more standardized.

　　Characteristic Structure and Product Advantages of High end Semi trailer: 1. Integrated Beam Structure: Welded by imported fully automatic tracking submerged arc welding machine, it has the special abilities of high load, good elasticity, high durability, and anti lateral deformation of semi-trailer special longitudinal beams. In addition, the unique multi angle structure of the longitudinal beam enhances the load-bearing capacity and deformation resistance of the entire longitudinal beam. 2. Characteristic through beam structure: The special through beam structure better disperses the weight of goods and reduces damage to the frame and bottom plate caused by goods. 3. Large diameter balance arm shaft pin: In order to better adapt to the complex environment of heavy load transportation, a large diameter balance arm shaft pin is used, which is impact resistant and heavy load resistant. Suspension system: adopting a unique new suspension system with high strength and strong impact resistance; The load on each axis is balanced, and the angle of the system pull rod is designed reasonably. During frequent bumps, it reduces the instantaneous friction and slip distance between the tire and the ground, effectively reducing tire wear. At the same time, the adjustable pull rod can adjust the wheelbase, which can effectively avoid tire eccentric wear and tire gnawing; The axle clamp is an integral casting component.
