Aviation Unit Load Device (ULD) Skeletal Trailer
The Aviation Unit Load Device (ULD) Skeletal Trailer is a precision-engineered intermodal transport chassis designed specifically for the rapid, secure transfer of aviation cargo containers and pallets (LD3, LD7, PMC, and PAG ULDs) between airports, cargo terminals, and logistics hubs. Featuring an integrated heavy-duty roller-bed deck and universal pop-up locking latches, it enables effortless manual or automated loading and unloading of sensitive air freight containers. Fabricated using high-tensile Q345B/Q550 structural steel and automated welding, it ensures supreme structural stability, shock absorption, and smooth apron handling. Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Roller-Bed Deck & Precision ULD Architecture
- High-Tensile Steel Construction: Fabricated using Q345B or Q550 high-tensile structural steel plates, providing exceptional torsional rigidity while maintaining a low-profile deck height for terminal compatibility.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees absolute structural joint integrity under constant apron transit stresses.
- Multi-Row Roller-Bed Deck: Equipped with heavy-duty, corrosion-resistant galvanized steel rollers and ball transfer units arranged in precision rows to facilitate frictionless horizontal movement of air cargo ULDs.
- Universal Pop-Up Locking Latches: Features spring-loaded, retractable ULD stop latches and guide rails strategically positioned across the deck perimeter to lock air containers securely during transit.
- Low-Profile Deck Layout: Engineered with a lowered center of gravity to ensure maximum stability when navigating tight airport cargo handling zones and transfer ramps.
2. Axle, Suspension & Pneumatic Braking Systems
- Axle Configurations: 2 or 3 lightweight yet durable axles (FUWA, BPW, or equivalent premium brands; 8T / 13T capacity per axle) optimized for smooth airport and short-haul logistics transit.
- Suspension Options: Air suspension systems or sensitive multi-leaf spring options designed to absorb apron vibrations and protect delicate aviation electronics and perishable air freight.
- Tire & Rim Setup: 4 to 8 heavy-duty commercial tires paired with high-load steel rims.
- Pneumatic Braking System: Advanced dual-line pneumatic braking system featuring emergency relay valves, automatic spring parking brakes, and ABS compliance ensuring safe terminal positioning.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: Heavy-duty 28-Ton two-speed landing gear (JOST / FUWA) and standard 50# (2") interchangeable kingpins for rapid tractor coupling.
- Electrical & Lighting System: 24V 7-pin LED lighting system with waterproof wiring harnesses and apron hazard marker lights meeting international aviation ground support safety standards.
- Standard Utility Add-ons: Side guide rollers, integrated safety bumpers, steel mudguards with anti-spray flaps, and a weather-sealed tool box.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the main beam and roller-bed frame structure; 1-Year warranty for rollers, latches, axles, and suspension components.
- Delivery Lead Time: 25 – 35 working days upon order confirmation.
- Packaging & Shipping: Nude packing; stacked or shipped via Ro-Ro vessel, Bulk Cargo ship, or Container.
- Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
