Heavy-Duty 4-Axle Chassis for Optimal Weight Distribution
Compared to standard 2-axle or 3-axle skeletal chassis, the 4-axle setup provides a significantly larger payload margin while complying with strict highway axle-load regulations.
Advantages of the 4-Axle Setup:
- Even Load Distribution: Spreads heavy container weight across 4 axles to prevent frame stress and excessive road impact.
- Enhanced Driving Stability: Minimizes sway and bounce during high-speed highway transport and long-distance hauling.
- Extended Component Life: Reduces wear on individual tires, brake drums, and suspension leaf springs.
Reinforced Q345 / T700 Steel Skeletal Frame
The main beam is submerged-arc welded using premium high-strength carbon steel. The open skeletal design drastically reduces tare weight without sacrificing load-bearing stiffness:
- High Anti-Torsion Strength: Resists frame twisting caused by uneven container loads or unpaved port logistics roads.
- Convenient Inspection: Open chassis structure allows quick access for daily maintenance of air tanks, brake lines, and electrical wiring.
- Durable Surface Protection: Shot-blasted steel frame finished with anti-corrosion primer and a protective polyurethane topcoat.
