Heavy-Duty Skeleton-Flatbed Dual-Purpose Trailer
The Heavy-Duty Skeleton-Flatbed Dual-Purpose Trailer is a highly versatile hybrid commercial transport semi-trailer engineered to perform as both a skeletal container chassis and a heavy-duty platform flatbed. Built with high-strength Q345B structural steel and automated submerged-arc welding, it features a open-frame skeletal spine fitted with removable or drop-in floor panels and an integrated multi-lock layout. This dual architecture allows operators to rapidly adapt between lightweight ISO container haulage and solid-floor general break-bulk freight transport, maximizing fleet operational utilization and minimizing deadhead miles. Equipped with 12 heavy-duty twist-locks, premium 13T axles, and air or mechanical suspension, it delivers exceptional payload efficiency across port terminals and long-haul intermodal logistics corridors. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Convertible Hybrid Chassis & High-Tensile Spine
- Dual-Purpose Modular Design: Features a reinforced skeletal sub-frame integrated with removable deck inserts or a modular steel floor, allowing instant conversion from a high-efficiency container skeleton into a solid open-deck flatbed.
- Q345B High-Strength Spine: Main longitudinal beams fabricated from high-yield Q345B steel using automated Submerged-Arc Welding (SAW), ensuring maximum resistance to bending and torsional fatigue under mixed-freight operations.
- 12 Multi-Lock Container Matrix: Standard 12-twist-lock arrangement designed to lock 1x40ft, 2x20ft, or single 20ft centered ISO shipping containers firmly to the skeletal cross-members.
2. Axle, Suspension & Pneumatic Braking Systems
- Heavy-Duty 3-Axle Setup: 3 commercial-grade axles (FUWA / BPW / HuaJin brands; 13T capacity per axle) tuned for balanced weight distribution and lower rolling resistance.
- Adaptable Suspension Architecture: Heavy-duty leaf spring setup (10pcs, 90x13mm) or pneumatic air suspension engineered to mitigate road vibration and protect structural frame joints.
- Advanced Pneumatic Braking System: High-response ABS air braking system (WABCO / Kemi / Haldex brands) ensuring consistent, safe, and controlled stopping performance.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: Heavy-duty 28-Ton two-speed landing gear (JOST / FUWA) combined with 50#(2") or 90#(3.5") kingpins for fast, reliable tractor coupling.
- Electrical & Lighting System: Weatherproof 24V LED lighting system with a 7-pin socket and 6-line wiring harness for total highway compliance and safety visibility.
- Corrosion Protection: Surface fully cleaned via shot-blasting, protected by anti-rust primer, and finished with double-coated polyurethane topcoats for extended service life.
