Multi-spool heavy-duty low-platen semi-trailer, with 8.25-15 tires, hydraulic gooseneck structure, the height of the loading platform can be automatically raised and lowered, the length of the cargo platform can be spliced at will, hydraulic automatic steering, and hydraulic pump station power system. Now it is necessary to introduce technology. The series of low flat semi-trailers have flat, concave beam and tire leaking structures. The frame is stepped and the longitudinal beam section is I-shaped, which has the characteristics of rigid height and strong height.
The frame of the series semi-trailer is a through-beam structure, and the longitudinal beam adopts a straight type or a gooseneck type. The webs are welded from 400mm to 550mm with manganese plates, the longitudinal beams are welded by automatic submerged arc welding, the frame is shot blasted, and the beams penetrate the longitudinal beams and weld the whole. The suspension adopts non-independent steel plate stamping rigid suspension (optional air suspension), which is composed of tandem steel plate springs and suspension supports; the structure is reasonable, with strong rigidity and strength, and is used to support the load and reduce the impact.
The low plane of the column of the truck rack ensures the stability of transportation, and it is suitable for carrying all kinds of construction machinery, large equipment and steel.
Carbon dioxide gas shielded welding; the entire frame is shot peened to make the vehicle more beautiful, strong and durable. The vehicle bridge is used to cross the girder, which effectively reduces the ground clearance of the cargo platform. The increased passing capacity of the vehicle can load objects with larger diameters. It is an ideal transportation tool suitable for transporting wind turbine towers and large-diameter cargo. The car can be made into a pull-out type according to customer requirements, and the middle is made into an arc shape to adapt to large-diameter round objects.
Sophisticated workmanship: the main components of the vehicle are processed by advanced equipment, and the longitudinal beams are welded by a fully automatic submerged arc welding machine imported from Germany; the assembly machine is used to realize the wheel and axle assembly, and the distance meter is used to ensure the wheelbase; the electric test bench is used for alignment The electric circuit of the car is debugged; the parts of the car are shot peened, which greatly enhances the adhesion of the paint.
Frame: The frame is a frame structure composed of longitudinal beams and reinforced beams welded by 16MN automobile steel. The strength, stiffness, and toughness of the frame are considered in a balanced manner. It has the characteristics of strong bearing capacity and no deformation.
Axle: The axle is made of high-quality axles produced by professional manufacturers, which has strong load-bearing capacity and is not easy to deform; at the same time, it can be equipped with domestic and foreign ABS anti-lock braking systems to reduce the braking distance and effectively prevent the wheels from locking during emergency braking. The phenomenon of vehicle sideslip, tail-flick, etc., improves the driving safety of the vehicle.
Suspension system: adopts the most unique new suspension system with high strength and strong impact resistance; each axle load is balanced, and the system tie rod angle design is reasonable. In the process of frequent turbulence, it reduces the instantaneous friction slip distance between the tire and the ground. Effectively reduce tire wear, while the adjustable tie rod can adjust the wheelbase, which can effectively avoid tire eccentric wear and tire gnawing; the axle clamp is an integral casting, and the lower clamp is the product.
Brake system: adopt safe and reliable
Circuit break air brake braking system, energy storage pump has parking brake function, select the relay valve with open performance. Multiple gooseneck structures: adopt a variety of gooseneck forms with low load-bearing surface, which can meet the transportation needs of different goods.
