Analysis of the advantages of 4-axis large cargo transportation high-low flatbed semi transporter technology

1、 Load capacity and structural stability
Four axis design enhances load-bearing capacity
The four axis layout significantly improves overall stability by dispersing loads. Taking the Q345 high-strength steel as the main beam of the vehicle as an example, its single transport capacity can reach 80-100 tons, which is about 30% higher than that of the three axle vehicle. For example, a certain model of main beam with a height of 500mm, combined with a cross shaped beam structure with upper and lower wing plates of 20mm and middle web plates of 12mm, can effectively reduce the risk of structural deformation when transporting heavy equipment such as wind turbine towers.
Low center of gravity design enhances safety
The sunken cargo platform reduces the center of gravity of the goods by 15% -20%, and with the dual line pneumatic braking system (including WABCO emergency relay valve), the braking distance can be shortened by more than 30% during long downhill or emergency braking. A test case shows that when fully loaded with 50 tons, the braking distance at an initial speed of 60km/h is reduced by 8 meters compared to a regular flatbed truck.
2、 Loading and unloading efficiency and adaptability to multiple scenarios
Open architecture supports multi-dimensional assignments
The rear dual spring loaded manual ramp (720mm wide) and side detachable guardrail design allow forklifts and cranes to operate synchronously from three directions. For example, when transporting a 36 ton excavator, the loading and unloading time is reduced by 40% compared to a closed truck, and no additional lifting equipment is required.
Compliance in the transportation of oversized goods
The sunken cargo platform increases the height limit of goods from 2.8 meters for standard flat plates to 3.2 meters, meeting the transportation needs of irregular goods such as wind turbine blades and steel structures. Combined with 2-inch or 3.5-inch interchangeable towing pins, it can adapt to different towing heads and achieve inter provincial intermodal transportation.
3、 Economy and maintenance convenience
Modular design reduces costs
Three flatbed semi trailers can be combined to transport ultra long goods (such as 40 meter wind turbine towers), reducing packaging costs through bare wax spraying technology. A case study of a wind power project shows that after adopting this scheme, the transportation cost per kilometer is reduced by 18%, and packaging material waste is also reduced.
Durability design extends service life
The main beam and side beams are made of “I” type high-strength steel, which increases the torsional stiffness by 50% compared to ordinary steel. Combined with 28 ton two speed manual support legs and polyurethane top coating (total dry film thickness ≥ 100 μ m), the structural lifespan can reach over 15 years in high-frequency usage scenarios.
