3 Axle 40FT Sidewall Semi Trailer Detailed Description
Reinforced Main Beam & Structural Integrity
To handle up to 60 tons without deformation, our main beam is constructed from Q345B high-tensile steel with a reinforced plate configuration: 14mm upper, 8mm middle, and 16mm lower. This provides a superior strength-to-weight ratio. The entire chassis undergoes automated submerged arc welding and a professional shot peening process, ensuring the paint adheres better and the structure remains rust-free in harsh climates.
Flexible Loading & Intermodal Compatibility
The 600mm-800mm (customizable) side walls are designed for quick assembly and disassembly. When the walls are removed, the trailer functions as a 40ft flatbed. To maximize your investment, we offer 12 sets of container twist locks as a standard option, allowing you to seamlessly integrate into intermodal logistics chains. The side beams are reinforced with 16mm or 18mm steel channels to prevent lateral bowing under heavy side-loads.
