Craftsmanship design of mechanical equipment, low flatbed transport vehicle, lightweight gooseneck low flatbed trailer

Description :

　　The low flatbed semi-trailer has no railing on the vehicle body and is widely used, mainly for medium and long-distance freight transportation. The series semi-trailer frame adopts a through beam structure, and the longitudinal beam adopts a straight movable goose neck type. The web height ranges from 400mm to 550mm, 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. Composed of a series of dry plate springs and suspension supports, the structure is reasonable, with strong rigidity and strength, used to support loads and mitigate impacts. Low flatbed semi trailers are usually used to transport heavy vehicles (such as tractors, buses, specialized vehicles, etc.), rail vehicles, mining machinery, forestry machinery, agricultural machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.), and other heavy cargo. The lower the center of gravity, the better the stability and safety, and the stronger the ability to transport ultra-high cargo and pass overhead obstacles. The structure and loading of low flatbed semi trailers usually adopt a concave beam (or well type) frame, with the front section of the frame being a goose neck (the traction pin of the goose neck is connected to the traction saddle on the tractor, and the rear end of the goose neck is connected to the semi-trailer frame), the middle section being the cargo platform (the lower part of the frame), and the rear end being the wheel frame (including the wheels). When loading mechanical equipment onto a low flatbed semi-trailer, it is usually done from the rear end of the semi-trailer, that is, by moving the mechanical equipment from the rear wheel frame or removing the wheels, and then fixing the mechanical equipment onto the semi-trailer.

　　The walking structure of the low flatbed semi-trailer is made of high-strength steel material, which has a light weight and ensures its ability to resist torsion, earthquake, and bumps, meeting different road bearing capacities. Liangshan Hongsheng Ruixin Manufacturing and Sales Company produces 13 meter low flatbed semi-trailer, 12 meter low flatbed trailer, 11 meter hook plate semi-trailer, 10 meter high low flatbed semi-trailer, 9.5 meter trailer, light concave beam hook plate semi-trailer, tire exposed low flatbed semi-trailer, 13 meter trailer plate, high-low low flatbed semi-trailer, three-axis low flatbed semi-trailer, mechanical transport semi-trailer, and flatbed excavator transport vehicle; Provide current prices for low flatbed semi trailers. The main plane of the frame cargo platform is low, ensuring smooth transportation and suitable for carrying various types of construction machinery, large equipment, and steel. Adopting three-axis balance, dual axis balance or rigid suspension, a mass balance block is installed between the front and rear steel plate springs, which can make the deflection of the front and rear steel plate springs change equally, and balance the force on the front and rear axles. CO2 gas inverter welding; The entire frame has undergone shot blasting treatment to make the vehicle more aesthetically pleasing. The entire vehicle is optimized and designed using advanced computer-aided design software. Based on the vehicle's load-bearing quality requirements, the frame is subjected to finite element analysis for scientific design and reasonable load distribution.

　　From the perspective of domestic demand, with the implementation of environmental protection production restrictions during the heating season in some provinces and cities, the steel production of low flatbed semi trailers will decrease in the later stage. On the one hand, environmental protection production restrictions have a certain impact on both supply and demand, and there will be certain prerequisites for their implementation in practice, rather than a one size fits all policy, which will not significantly reduce steel production; On the other hand, after the new conference, more targeted policies and measures to stabilize growth will be released, and the national economy is expected to continue to maintain a steady and positive development trend. Infrastructure construction, as well as major steel industries such as machinery, specialized semi trailers, and home appliances, are expected to maintain rapid growth, and steel demand will remain stable.
