4-Axle 50ft Super-Long Cargo Flatbed Trailer
The 4-Axle 50ft Super-Long Cargo Flatbed Trailer is an extended-length, high-capacity commercial transport semi-trailer engineered specifically for oversized general cargo, long steel pipes, timber, precast components, and flexible multi-container logistics. Built with high-strength Q345B/Q550 structural steel and automated submerged-arc welding, it delivers superior longitudinal frame stiffness, anti-sag resistance, and optimal payload distribution across a 4-axle arrangement. Equipped with multiple container twist-locks, 13T-16T heavy-duty axles, and air or mechanical suspension, it ensures maximum stability and operational flexibility across long-distance highways and heavy transport corridors. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Ultra-Long Frame & Reinforced High-Tensile Design
- Q345B/Q550 Reinforced Long-Span Spine: Main longitudinal chassis beams constructed from extra-thick Q345B/Q550 high-strength steel plates and continuous automated Submerged-Arc Welding (SAW) to prevent frame deflection over a 50ft platform.
- High-Capacity Cargo Deck: Heavy-duty 3mm/4mm checkered plate flooring engineered for high wear resistance and anti-slip traction when carrying long structural loads or heavy machinery components.
- Versatile Container Lock Layout: Configured with 12 to 16 heavy-duty twist-locks for multi-modal flexibility, securing combinations of ISO containers or oversized break-bulk freight.
2. Axle, Suspension & Pneumatic Braking Systems
- High-Payload 4-Axle Setup: 4 premium commercial axles (FUWA / BPW / HuaJin brands; 13T/16T capacity per axle) configured to maximize legal axle weight distribution over extended spans.
- Robust Suspension Architecture: Heavy-duty leaf spring suspension (10pcs, 90x13mm / 90x16mm) or air suspension designed to absorb heavy dynamics and stabilize high center-of-gravity loads.
- Advanced Pneumatic Braking System: High-performance ABS air braking system (WABCO / Kemi / Haldex brands) ensuring reliable, smooth, and immediate stopping control under full load capacity.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: Heavy-duty 28-Ton two-speed landing gear (JOST / FUWA) paired with interchangeable 50#(2") or 90#(3.5") kingpins for stable tractor coupling.
- Electrical & Lighting System: Weatherproof 24V LED lighting system featuring side-marker clearance lamps, a 7-pin socket, and 6/7-line wiring harness for international highway compliance.
- Surface Protection: Prepared via thorough sandblasting, followed by anti-rust primer and double-coated polyurethane topcoats for high environmental durability.
