Product Introduction
I. Definition & Structural Analysis
The Dual-Articulated Flatbed Trailer is a heavy-duty transport solution designed for extra-long and overweight cargo, featuring two sets of articulated joints connecting front and rear sections. Core components include:
Front power module: Powered driving unit (diesel/electric options)
Dual-articulation system: Two hydraulic steering joints (±90° horizontal rotation / ±15° vertical pitch)
Rear load platform: Low-center deck (ground clearance ≤1.2m) with multi-axle independent suspension
✨ Design advantage: Reduces turning radius by 40% vs. rigid trailers and adapts to uneven off-road terrain.
II. Core Performance & Technical Highlights
| Parameter | Specification | Functional Advantage |
|---|---|---|
| Payload capacity | 80-400 tons (modular expansion to 1,000 tons) | Transports OOG cargo like wind turbine blades |
| Steering system | Electro-hydraulic control + multi-axle coordination | Navigates S-curves and complex routes |
| Terrain adaptability | 25% max grade + cross-axle stability | Mines/construction site mobility |
| Safety control | Real-time CG monitoring + auto ballast adjustment | Anti-rollover (tilt alert ≥8°) |
Innovations:
Lift axles: Retractable when empty to reduce tire wear
Modular extensions: Platform lengthening with 3/6/9m inserts
III. Typical Applications
| Industry | Cargo | Case Requirement |
|---|---|---|
| Wind energy | Turbine blades (70-90m length) | Mountainous terrain with 30% grades |
| Power projects | Transformers (≥300 tons) | Rural roads with 4.5m width |
| Mining | Excavator chassis | ≥15km/h on unpaved surfaces |
| Aerospace/defense | Rocket sections | Vibration control ≤0.5g |
✅ Scenario advantage: For blade transport in mountains, dual articulation reduces blade-tip swing by 60%, preventing collisions.
IV. Comparison vs. Rigid Flatbed Trailers
| Capability | Dual-Articulated Trailer | Rigid Trailer |
|---|---|---|
| Min. turning radius | 16m (for 40-ft trailer) | 22m |
| Ground clearance | 300mm axle tolerance | ≤150mm |
| Max cargo length | Theoretically unlimited | ≤30m |
| Complex route cost | Eliminates escort vehicles | Requires traffic control |
