48ft Extended Skeletal Container Semi-Trailer
The 48ft Extended Skeletal Container Semi-Trailer is a specialized, long-span intermodal transport chassis engineered specifically for the secure and compliant hauling of 48ft domestic and international shipping containers. Fabricated using premium ultra-high-tensile T700 structural steel and automated submerged-arc welding, it is heavily reinforced to completely eliminate mid-span deflection under full commercial payloads. Featuring specialized rear extension profiles, precise ISO twist-locks, and robust multi-axle configurations (FUWA/BPW), it delivers exceptional structural longevity and highway stability for North American and transcontinental long-haul corridors. Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Ultra-High-Tensile T700 Long-Span Chassis
- Premium T700 Steel Construction: Fabricated entirely from ultra-high-tensile T700 structural steel plates, providing superior yield strength and exceptional rigidity to support extended-length cargo spans.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees absolute structural weld integrity under severe long-span highway transit stresses.
- Anti-Deflection Structural Design: Engineered with deep-profile box-section main beams and internal gusset reinforcements to completely prevent mid-span sagging and structural fatigue under full 48ft payload weights.
- Precision ISO Twist-Locks: Equipped with heavy-duty cast steel twist-locks positioned precisely to lock 48ft domestic and maritime containers firmly against longitudinal and lateral displacement.
2. Axle, Suspension & Pneumatic Braking Systems
- Axle Configurations: 3 axles (FUWA, BPW, or equivalent premium brands; 13T / 16T capacity per axle) optimized for long-span weight distribution and highway axle-load limits.
- Suspension Options: Heavy-duty multi-leaf spring suspension or smooth-riding air suspension systems designed for stable load balancing across varied regional highway networks.
- Tire & Rim Setup: 12 heavy-duty commercial tires paired with 8.25-22.5 or 11.00R20 high-load steel rims.
- Pneumatic Braking System: Advanced dual-line pneumatic braking system featuring emergency relay valves and ABS compliance matching international highway safety codes.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: 28-Ton two-speed landing gear (JOST / FUWA) and 50# (2") or 90# (3.5") interchangeable kingpins for rapid tractor coupling.
- Electrical & Lighting System: 24V 7-pin LED lighting system with waterproof wiring harnesses meeting international road safety directives.
- Standard Utility Add-ons: 1–2 spare tire carriers, steel mudguards with anti-spray flaps, and a lockable weather-sealed tool box.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the main beam; 1-Year warranty for axles and suspension components.
- Delivery Lead Time: 20 – 30 working days upon order confirmation.
