Straight-Beam 40ft Skeletal Container Chassis
The Straight-Beam 40ft Skeletal Container Chassis is a specialized, uniform-profile intermodal transport semi-trailer engineered specifically without a traditional gooseneck drop. Featuring a flat, continuous straight-beam structure, it provides exceptional uniform load distribution across the entire frame length, making it ideal for specialized low-clearance container yards, hazardous material container transport, and specialized industrial frame configurations. Fabricated using high-tensile Q345B/Q550/Q700 steel and automated submerged-arc welding, it is equipped with 12 heavy-duty ISO twist-locks, reinforced crossmembers, and robust multi-axle configurations (FUWA/BPW). Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Uniform Straight-Beam Chassis & High-Tensile Structure
- High-Tensile Steel Construction: Fabricated with Q345B, Q550, or Q700 structural steel plates, providing superior torsional rigidity and uniform stress distribution across the entire flat-deck profile.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees exceptional joint durability and structural integrity under rigorous daily industrial cycles.
- Continuous Straight-Beam Profile: Designed without a gooseneck step, offering a uniform height profile that simplifies frame manufacturing, enhances structural longevity, and prevents stress concentrations.
- Low-Clearance Yard Compatibility: Engineered specifically for specialized low-clearance container yards, automated gantry terminals, and specialized intermodal transshipment hubs.
- Heavy-Duty ISO Twist-Locks: Equipped with 12 precision-cast ISO twist-locks strategically positioned to secure either a single 40ft container or two 20ft containers uniformly.
2. Axle, Suspension & Pneumatic Braking Systems
- Axle Configurations: 2 or 3 axles (FUWA, BPW, or equivalent premium brands; 13T / 16T capacity per axle) optimized for uniform load transfer and long-distance highway performance.
- Suspension Options: Heavy-duty multi-leaf spring suspension or smooth-riding air suspension systems designed for stable load balancing across varied road conditions.
- Tire & Rim Setup: 8 to 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.
- 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).
