40 Tons Side Wall Trailer Advantages

Frame: The frame utilizes a space frame structure, expertly welded with longitudinal beams and integrated through-type cross beams. This construction effectively balances strength, rigidity, and toughness, ensuring a robust load-bearing capacity without deformation.

Structure: The primary beam adopts a through-beam design, while the longitudinal beam options include flat or gooseneck types. Web heights range from 400 to 500 units. Longitudinal beams are precision-welded using automatic submerged arc welding. The frame undergoes meticulous shot blasting treatment, and the cross beam is seamlessly integrated with the longitudinal shaft through welding.

Suspension System: An innovative suspension system is implemented, characterized by its exceptional strength and impact resistance. It maintains balanced axle loads, and the system’s tie rod angles are thoughtfully engineered to minimize tire-ground friction during rough rides, reducing tire wear. Additionally, adjustable tie rods allow axle spacing customization, effectively preventing wheel bias-grinding and gnawing issues.
