Modular Interchangeable-Beam Skeletal Chassis
The Modular Interchangeable-Beam Skeletal Chassis is a revolutionary, highly versatile intermodal transport trailer engineered to provide maximum fleet adaptability through bolted modular frame architecture. Allowing fleet operators to interchange 20ft, 40ft, or specialized extension beams easily within a single chassis investment, it eliminates the need to maintain dedicated single-size trailers. Fabricated using high-tensile Q345B/Q550 structural steel and automated submerged-arc welding at core connection nodes, it delivers supreme structural rigidity, seamless modular reconfigurability, and unparalleled capital expenditure efficiency. Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Modular Bolted Chassis & High-Tensile Architecture
- High-Tensile Steel Construction: Fabricated using Q345B or Q550 high-tensile structural steel plates, featuring reinforced flange plates and computer-optimized stress-relief joint zones.
- Automated SAW & Precision Machining: Core structural sections welded via automated Submerged-Arc Welding (SAW), followed by CNC precision machining at connection interfaces to guarantee perfect alignment during beam swaps.
- Bolted Modular Interchangeability: Utilizes high-strength Grade 10.9 flanged fasteners and shear-resistant alignment dowels, enabling maintenance crews to swap 20ft, 40ft, or extension modules rapidly.
- Universal Twist-Lock Integration: Equipped with multi-position retractable and fixed ISO twist-locks that adjust automatically to the active modular beam configuration.
- Asset Optimization & CapEx Efficiency: Empowers fleet operators to reconfigure a single chassis investment for varying container demands, drastically reducing total fleet size and maintenance overhead.
2. Axle, Suspension & Pneumatic Braking Systems
- Heavy-Duty Axle Configurations: 2 or 3 premium axles (FUWA, BPW, or equivalent premium brands; 13T / 16T capacity per axle) engineered to handle varied load distributions across modular lengths.
- Suspension Options: Smooth-riding air suspension systems or heavy-duty multi-leaf spring options designed to accommodate shifting center-of-gravity profiles.
- Tire & Rim Setup: 8 to 12 low-rolling-resistance commercial tires paired with 8.25-22.5 or 11.00R22.5 high-efficiency steel rims.
- Advanced Pneumatic Braking System: Dual-line pneumatic braking system featuring quick-release modular airline couplings, emergency relay valves, and full ABS compliance ensuring safe stopping power across all configurations.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: 28-Ton two-speed heavy landing gear (JOST / FUWA) with reinforced base plates and standard 50# (2") or 90# (3.5") interchangeable kingpins.
- Electrical & Lighting System: 24V 7-pin LED lighting system featuring modular, plug-and-play waterproof wiring harnesses that adapt easily to extended or shortened frame lengths.
- Standard Utility Add-ons: Heavy-duty steel mudguards with anti-spray flaps, dual spare tire carriers, and a lockable weather-sealed tool/hardware chest for modular fasteners.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the main structural frame modules; 1-Year warranty for axles, suspension, and pneumatic braking components.
- Delivery Lead Time: 35 – 45 working days upon order confirmation and modular specification selection.
- Packaging & Shipping: Nude packing; stacked or shipped via Ro-Ro vessel, Bulk Cargo ship, or Container.
- Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
