Key Structural & Performance Features
1. Tri-Axle Architecture & High-Capacity Deck Design
- High-Tensile Steel Construction: Fabricated using Q345B high-tensile structural steel plates, providing superior web resilience and torsional balance required for extended three-axle frame lengths.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees absolute structural joint integrity under continuous high-load highway transit.
- Optimized Tri-Axle Load Sharing: Engineered with a balanced three-axle bogie suspension system that distributes gross vehicle weight evenly across multiple tire contact points, minimizing road wear and meeting regional bridge-formula laws.
- Multi-Stage Hydraulic Deck Lift: Advanced hydraulic cylinders and precision control valves operate upper and lower movable ramps, facilitating smooth, independent loading of upper-tier vehicles.
- Punch-Hole Traction Decks: High-strength stamped punch-hole steel flooring offers maximum tire grip during wet loading conditions while maintaining an optimized tare weight profile.
2. Tri-Axle Suspension, Wheels & Pneumatic Braking Systems
- Heavy-Duty Tri-Axle Setup: 3 premium heavy-duty commercial axles (FUWA, BPW, or equivalent brands; 13T capacity per axle) featuring robust spindles and maintenance-friendly hubs.
- Suspension Options: Heavy-duty multi-leaf spring equalizer suspension or smooth air-ride suspension systems designed to protect sensitive vehicle frames and electronics during transit.
- Tire & Rim Setup: 12 to 14 low-profile commercial tires paired with 8.25-22.5 or 295/80R22.5 high-load steel rims.
- Advanced Pneumatic Braking System: Dual-line pneumatic braking system featuring emergency relay valves, automatic slack adjusters, and full ABS compliance for safe, controlled stopping power.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: 28-Ton two-speed heavy landing gear (JOST / FUWA) and standard 50# (2") or 90# (3.5") interchangeable kingpins.
- Electrical & Lighting System: 24V 7-pin LED lighting system featuring waterproof wiring harnesses, clearance side markers, and rear multi-chamber lamp clusters.
- Standard Utility Add-ons: Retractable loading ramps, side safety rails, heavy-duty steel mudguards with anti-spray flaps, and a lockable weather-sealed strap and tool chest.
