Core Advantages & Manufacturing Excellence

1. High-Tensile Q345B Steel Architecture

The backbone of our 80-ton trailer is a specialized 500mm main beam forged from Q345B high-strength steel. This provides an exceptional strength-to-weight ratio, ensuring the trailer resists sagging and torsional stress even under maximum load.

2. Quad-Axle Precision Performance

The four-axle configuration distributes the 80-ton weight evenly, reducing ground pressure and improving road safety. Buyers can specify FUWA or BPW axle systems, which feature advanced low-alloy beams with no welding points for a maintenance-free lifespan of up to 400,000 kilometers.

3. Advanced Robotic Welding & Durability

Utilizing national-standard robotic welding technology, every joint is meticulously fused. Our process includes 30 minutes of additional welding time compared to standard models, guaranteeing the best structural results.

4. 9-Year Anti-Rust Electrophoresis Painting

To withstand harsh environments and maritime transport, the entire trailer frame undergoes a full-body electrophoresis painting process. This provides 360-degree coverage and paint adhesiveness that lasts up to 9 years.

Professional Customization Options

Cargo Platform: Choose between Flatbed, High-Low-High (Drop Deck), or Ultra-low configurations. Dimensions can be tailored to your specific regional transport regulations.
