Wind Tower Section Lowbed Semi-Trailer
The Wind Tower Section Lowbed Semi-Trailer is an extra-heavy-duty transport trailer engineered specifically for hauling large-diameter wind turbine tower sections, heavy tubular steel cylinders, and renewable energy infrastructure components. Built with a load capacity ranging from 30 to 150+ tons, it is fabricated from Q345B/Q550/Q700/T700 high-tensile steel using automated submerged-arc welding. Its ultra-low drop-deck configuration (700–1,100 mm) equipped with saddle cradles and extendable side outriggers significantly lowers the height of massive tubular loads, ensuring bridge clearance compliance, roll resistance, and maximum driving stability on mountain roads. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Heavy-Duty Frame Built for Large-Diameter Tubular Loads
- High-Tensile Steel Structure: Constructed with Q345B, Q550, Q700, or T700 steel to handle severe point-load concentrations and high bending moments from cylindrical tower segments.
- Automated SAW Welding: Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees superior structural integrity under dynamic road vibration and mountain transport conditions.
- Reinforced Main Beams: Main beam height options of 450 mm, 500 mm, or 520 mm with extra-thick top and bottom flange plates.
- Anti-Skid Checkered Platform: 4 mm, 5 mm, or 6 mm checkered steel floor reinforced with dense I-beam crossmembers to withstand extreme point pressure from steel saddle mounts.
2. Axle, Suspension & Hydraulic Steering Systems
- Axle Configurations: 2 to 6 axles (Supports FUWA, BPW, Huajin, or hydraulic steerable axles; 13T / 16T / 20T / 25T capacity per axle).
- Hydraulic / Self-Steering Options: Optional hydraulic steerable axles with remote control or automatic trailing steering for tight turns on wind farm access roads.
- Tire & Rim Setup: 8 to 24 heavy-duty tires paired with 6.75-17.5 or 9.00-22.5 high-load steel rims.
- Suspension Options: Multi-leaf heavy-duty spring suspension or hydraulic lifting suspension for ground clearance adjustment.
- Braking System: Dual-line ABS anti-lock braking system (WABCO, Kemi, Haldex, or equivalent).
3. Tower Section Loading & Cargo Securing Setup
- Adjustable Saddle Cradles: Equipped with rubber-lined saddle mounts and clamping adapters to firmly cradle round tower barrels without damaging protective paint coatings.
- Extendable Outriggers: Outriggers/side brackets extend platform width by 250–300 mm per side to fit wide-diameter base tower sections.
- Gooseneck Configurations: Fixed, detachable (front-loading), hydraulic, or foldable gooseneck designs for flexible loading configurations.
- Cargo Securing Systems: GR120 heavy-duty lashing chains, steel wheel chocks, and ratchet binders to lock tubular loads against rolling.
- Standard Accessories: 28-Ton two-speed landing gear (JOST / FUWA), 50# (2") or 90# (3.5") interchangeable kingpins, 24V 7-pin LED lighting system, 1–2 spare tire carriers, and a waterproof tool box.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the main beam; 1-Year warranty for axles.
- Delivery Lead Time: 25 – 35 working days upon order placement.
- Packaging & Shipping: Nude packing; shipped via Ro-Ro vessel, Bulk Cargo ship, or Container.
- Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
