Tri-Axle 40ft Heavy-Duty Skeletal Semi-Trailer
The Tri-Axle 40ft Heavy-Duty Skeletal Semi-Trailer is an exceptionally rugged, high-capacity intermodal transport chassis engineered specifically for hauling high-density, overweight 40ft industrial containers across rugged regional highways and demanding infrastructural corridors. Fabricated using heavy-gauge Q345B/Q550/T700 high-tensile structural steel and automated submerged-arc welding, it is equipped with 3 heavy-duty 16-ton axles (FUWA/BPW), reinforced box-type main beams, 12 heavy-duty ISO twist-locks, and a robust multi-leaf suspension system. Built to withstand extreme vertical and torsional loads, it maximizes industrial payload capacity while ensuring superior structural durability and highway stability. Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Reinforced Tri-Axle Chassis & High-Tensile Structure
- High-Tensile Steel Construction: Fabricated using heavy-gauge Q345B, Q550, or T700 high-tensile structural steel plates, engineered with increased web thickness to absorb extreme static and dynamic loads.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees absolute structural joint integrity under severe regional highway vibrations and heavy-weight stresses.
- Reinforced Box-Type Main Beams: Features deep-profile box-section main beams and dense crossmember distributions to completely eliminate frame sagging under high-density, overweight industrial cargo.
- Heavy-Duty ISO Twist-Locks: Equipped with 12 precision-cast, high-strength ISO twist-locks strategically positioned to lock heavy 40ft or dual 20ft industrial containers firmly against displacement.
2. Heavy-Duty Axle, Suspension & Pneumatic Braking Systems
- Tri-Axle Heavy-Duty Configuration: Configured with 3 heavy-duty 16-ton axles (FUWA, BPW, or equivalent premium brands) designed for high-endurance heavy freight transport.
- Suspension Options: Reinforced multi-leaf spring suspension (heavy leaf counts with wide spacing) engineered to distribute high axle loads evenly across unpaved or rugged regional highways.
- Tire & Rim Setup: 12 heavy-duty commercial tires paired with 11.00R20 or 12R22.5 high-load steel rims.
- High-Performance Pneumatic Braking System: Advanced dual-line pneumatic braking system featuring emergency relay valves, large-capacity air reservoirs, and ABS compliance ensuring reliable stopping power under full overweight payloads.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: 28-Ton two-speed heavy landing gear (JOST / FUWA) and reinforced interchangeable kingpins (50# or 90#) for secure heavy tractor coupling.
- Electrical & Lighting System: 24V 7-pin LED lighting system with waterproof wiring harnesses and heavy-duty protective light guards meeting international road safety directives.
- Standard Utility Add-ons: Dual spare tire carriers, steel mudguards with anti-spray flaps, and a large 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).
