Key Conclusions: The transportation of wind turbine generator sets requires specialized vehicles such as hydraulic flatbed trucks and blade transport semi-trailers. Ordinary trucks cannot meet the transportation needs of oversized and heavy components. The blades of these wind turbine generator sets are typically over 90 meters long, and the nacelles weigh over 200 tons. Ordinary vehicles pose safety hazards such as insufficient turning radius and overloading. Specialized vehicles, through modular design, hydraulic suspension systems, and longitudinal extension capabilities, can achieve dry-tonnage transportation and dynamic obstacle avoidance, making them core tools for ensuring the safe transportation of wind power equipment.
Hydraulic Flatbed Trucks: These dry-tonnage mobile platforms employ a modular splicing design. Single-axle loads can reach 30-60 tons. The hydraulic suspension system automatically adjusts the platform height to ensure the equipment remains level during transportation. Their maximum load capacity exceeds 1000 tons, enabling the transportation of oversized components such as generator sets and towers. The modular structure allows for flexible combination of platform lengths according to cargo dimensions to adapt to the transportation needs of wind power equipment of different specifications.
Wind Turbine Blade Transport Semi-Trailers: Designed for Extra-Long Blades
This series of semi-trailers comes in three types: telescopic, axle-mounted, and lift-mounted. The telescopic semi-trailer uses a hydraulically operated longitudinally telescopic platform, with a maximum transport length of 95 meters. The axle-mounted semi-trailer uses a multi-axle steering system, reducing the turning radius by 40% compared to ordinary vehicles. The lift-mounted semi-trailer is equipped with a hydraulic lifting device, which can raise the blades to a height of over 5 meters, eliminating the need to navigate low obstacles such as bridges. All three types are equipped with a hydraulic steering system, with a minimum turning radius of less than 25 meters.
Specialty Transport Vehicles: Customized Functional Solutions
These rotating obstacle-avoidance transport vehicles are developed for complex road conditions. Hydraulic control allows for 360-degree blade rotation, adjusting the transport angle in narrow sections. Some models integrate lifting, rotating, and hydraulic steering functions, with dynamically adjustable fulcrum positions, reducing the overall length of the transport vehicle by 30%. The cost per trip for these vehicles is approximately 40 RMB/km, higher than ordinary trucks, but the transport cycle can be reduced by more than 50%.
