Extendable Intermodal Skeletal Container Trailer
The Extendable Intermodal Skeletal Container Trailer is an advanced, highly adaptable transport chassis engineered specifically with a mechanical sliding beam extension mechanism. This dynamic system allows fleet operators to adjust the chassis overall length smoothly from a compact 20ft configuration up to 45ft or 53ft containers, accommodating a wide spectrum of maritime and domestic shipping box sizes. Fabricated using high-tensile Q345B/Q550/T700 structural steel and automated submerged-arc welding, it features heavy-duty slide rails, locking pin assemblies, precision ISO twist-locks, and robust multi-axle configurations (FUWA/BPW). Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Telescopic Sliding Beam Chassis & High-Tensile Structure
- High-Tensile Steel Construction: Fabricated using Q345B, Q550, or T700 high-tensile structural steel plates, providing exceptional torsional rigidity and structural endurance across sliding sections.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees absolute structural joint integrity under frequent telescopic adjustment cycles.
- Mechanical Sliding Beam Extension Mechanism: Features heavy-duty internal box-in-box slide rails, pneumatic/manual safety locking pins, and rollers designed for smooth, reliable length adjustments from 20ft to 45ft/53ft containers.
- Precision ISO Twist-Locks: Multi-position cast steel ISO twist-locks strategically placed along the main frame and extending tail sections to lock various container sizes securely.
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 variable length weight distributions.
- Suspension Options: Heavy-duty multi-leaf spring suspension or smooth-riding air suspension systems designed for stable load balancing across diverse container spans.
- 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 ensuring reliable, responsive stopping safety.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: 28-Ton two-speed heavy landing gear (JOST / FUWA) and standard 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 and extendable rear marker light wiring meeting international safety directives.
- Standard Utility Add-ons: Spare tire carriers, steel mudguards with anti-spray flaps, and a lockable weather-sealed tool box.
