[0002] Wind turbine tower is an important part of wind turbine generator set, with diameter generally between 2-5 meters, length between 20-40 meters, and weight between 20-100 tons. The transportation of wind turbine tower is a difficult point in wind power generation project, because the wind turbine tower is large in size, heavy in weight, and irregular in shape, which can easily cause instability and vibration of the transportation vehicle, affecting transportation safety and efficiency. At present, there are two commonly used ways to transport wind turbine tower: one is to use a special ultra-low flatbed truck to place the wind turbine tower horizontally on the flatbed truck, and then fix it with ropes or chains; the other is to use a special bracket truck to place the wind turbine tower vertically on the bracket truck, and then fix it with buckles or bolts. Both of these transportation methods have some disadvantages: the first method makes the wind turbine tower easily deformed or damaged by external forces; the second method requires height restrictions, and the wind turbine tower is prone to swing and tilt, affecting transportation stability and safety. Therefore, a new method of transporting wind turbine towers that can provide auxiliary support and fixation at multiple positions of wind turbine towers is needed, which can effectively reduce the vibration and swing of wind turbine towers during transportation and improve transportation safety and efficiency.
