Flatbed Semi-Trailer with Sunken Wheel-Pockets
The Flatbed Semi-Trailer with Sunken Wheel-Pockets is a specialized low-profile commercial transport semi-trailer engineered specifically for over-height wheeled machinery, large agricultural tractors, construction equipment, and tall general cargo requiring ultra-low deck height. Built with high-strength Q345B/Q550 structural steel and automated submerged-arc welding, it features integrated wheel-pocket recesses engineered into the platform deck over the suspension area. This allows machinery wheels to drop directly into the chassis pockets, significantly lowering overall transport height to easily clear bridge and tunnel restrictions. Equipped with pocket cover plates for full flat-deck versatility, 13T heavy-duty low-bed axles, and responsive air or mechanical suspension, it delivers maximum clearance, cargo stability, and operational efficiency across demanding heavy-haul logistics networks. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Sunken Wheel-Pocket Architecture & Dual-Purpose Deck
- Integrated Wheel-Pocket Design: Precision-engineered wheel wells sunken into the rear platform frame that allow wheeled loaders, tractors, or heavy vehicles to park directly in the chassis recesses, cutting overall cargo height by 200–400mm.
- Removable Steel Cover Plates: Supplied with heavy-duty structural steel filler plates that fit flush over the wheel pockets, instantly converting the vehicle back into a standard smooth flatbed for containerized or general break-bulk freight.
- Q345B/Q550 Reinforced Spine: Main longitudinal beams constructed with high-yield steel and automated Submerged-Arc Welding (SAW) to maintain structural integrity despite chassis cutout profiles.
2. Axle, Suspension & Pneumatic Braking Systems
- Low-Profile 3-Axle Setup: 3 commercial-grade low-bed axles (FUWA / BPW / HuaJin; 13T capacity per axle) matched with small-diameter heavy-duty tires to further minimize deck elevation.
- Low-Slung Suspension Architecture: Compact multi-leaf spring setup (10pcs, 90x13mm) or specialized low-profile pneumatic air suspension engineered to absorb severe road impacts and lower center-of-gravity.
- Advanced Pneumatic Braking System: High-response ABS air braking system (WABCO / Kemi / Haldex brands) ensuring controlled, smooth, and immediate stopping power under full load capacity.
3. Operational Accessories & Safety Setup
- Landing Gear & Kingpin: Heavy-duty 28-Ton two-speed landing gear (JOST / FUWA) combined with 50#(2") or 90#(3.5") interchangeable kingpins for reliable tractor coupling.
- Electrical & Lighting System: Weatherproof 24V LED lighting system featuring a 7-pin socket and 6-line wiring harness for total highway safety compliance.
- Corrosion Protection: Surface thoroughly cleaned via shot-blasting, coated with anti-rust primer, and finished with double-coated polyurethane topcoats for long-term weather resilience.
