20ft Standard Skeletal Container Semi-Trailer
The 20ft Standard Skeletal Container Semi-Trailer is an essential, high-efficiency intermodal transport chassis engineered specifically for the secure, rapid, and compliant short-haul or long-distance hauling of standard 20ft ISO maritime cargo containers. Fabricated using high-tensile Q345B/Q550/Q700 steel and automated submerged-arc welding, it features 4 heavy-duty ISO twist-locks, a lightweight yet torsion-resistant structural frame, and optimized multi-axle configurations (FUWA/BPW). Designed for port terminals, container yards, and factory logistics, it maximizes payload capacity, ensures strict international highway safety standards, and offers exceptional durability under intensive daily operational cycles. Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Lightweight Yet Rigid Chassis & High-Tensile Structure
- High-Tensile Steel Construction: Fabricated with Q345B, Q550, or Q700 structural steel, providing an optimal balance of high yield strength and reduced tare weight to maximize payload efficiency.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees exceptional joint durability and structural integrity under dynamic port-to-factory transport stresses.
- Optimized Skeletal Profile: Streamlined open-frame design eliminates dead weight while maintaining superior resistance against twisting moments and heavy vertical loads.
- Heavy-Duty ISO Twist-Locks: Equipped with 4 precision-cast ISO twist-locks positioned at the corners to lock 20ft containers firmly against displacement during transit.
2. Axle, Suspension & Braking Systems
- Axle Configurations: 2 axles (FUWA, BPW, or equivalent premium brands; 13T / 16T capacity per axle) optimized for dependable short-haul and highway performance.
- Suspension Options: Heavy-duty multi-leaf spring suspension or smooth-riding air suspension systems designed for stable load balancing.
- Tire & Rim Setup: 8 heavy-duty commercial tires paired with 8.25-22.5 or 11.00R20 high-load steel rims.
- Braking System: Dual-line ABS anti-lock braking system (WABCO, Kemi, Haldex, or equivalent) ensuring reliable stopping safety under full commercial payloads.
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.
