Flatbed Semi-Trailer with Rear Foldable Loading Ramps
The Flatbed Semi-Trailer with Rear Foldable Loading Ramps is a multi-functional commercial transport semi-trailer engineered specifically for self-propelled construction machinery, wheeled loaders, excavators, and general break-bulk freight. Built with high-strength Q345B structural steel and automated submerged-arc welding, it features heavy-duty, spring-assisted or hydraulic folding rear ramps that allow tracked and wheeled equipment to drive directly onto the platform deck. The integrated flatbed platform comes equipped with multi-position container twist-locks, durable 13T axles, and robust mechanical or air suspension, offering contractors and logistics operators a versatile dual-purpose solution for machinery drive-on transport and standard intermodal freight hauling. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Foldable Rear Ramp Assembly & Dual-Purpose Deck
- Heavy-Duty Rear Foldable Ramps: Reinforced steel loading ramps featuring dual high-tension assist springs or optional hydraulic actuators, enabling safe, low-angle drive-on access for heavy machinery while stowing vertically or folding flat onto the deck during transport.
- Q345B High-Strength Structural Spine: Main longitudinal chassis frame constructed from high-yield Q345B steel plates and continuous Submerged-Arc Welding (SAW) to withstand severe concentrated drive-on wheel loads.
- High-Traction Deck & Container Locks: Thickened 4mm/5mm checkered steel plate flooring fitted with 12 multi-position ISO twist-locks, permitting seamless switching between machinery roll-on loading and containerized freight transport.
2. Axle, Suspension & Pneumatic Braking Systems
- Reliable 3-Axle Configuration: 3 commercial-grade axles (FUWA / BPW / HuaJin brands; 13T capacity per axle) calibrated for optimal axle load distribution under heavy machinery loads.
- Robust Suspension Architecture: Heavy-duty multi-leaf spring suspension (10pcs, 90x13mm) or pneumatic air suspension engineered to absorb heavy dynamic loading shocks and preserve frame integrity.
- Advanced Pneumatic Braking System: High-response ABS air braking system (WABCO / Kemi / Haldex brands) ensuring safe, controlled, and immediate stopping power under full payload conditions.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: Heavy-duty 28-Ton two-speed landing gear (JOST / FUWA) combined with interchangeable 50#(2") or 90#(3.5") kingpins for fast, secure tractor coupling.
- Electrical & Lighting System: Weatherproof 24V LED lighting system featuring a 7-pin socket and 6-line wiring harness for total highway compliance and safety visibility.
- 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.
