Fan blade transport semi-trailers include ordinary pull-out type fan blade transport semi-trailers, axial fan blade transport semi-trailers, and lifting type fan blade transport semi-trailers. Now let’s introduce to each of you:

　　① The ordinary pull-out type fan blade transport semi-trailers is somewhat similar to the low plate transport vehicle, but its beam is designed by using the buckle box, and the beam is pulled to adjust the length of the vehicle to adapt to the transportation of fan blades of different lengths. It is understood that the current domestic pull-out type fan blade transport semi-trailer can reach up to 50 meters.

　　② The biggest difference between the axial fan blade transport semi-trailers and ordinary pull-out type fan blade transport semi-trailers is that the chassis adopts the hydraulic axis design, the cargo surface of the fan blade truck is lower, and the steering is more flexible.

　③ The lifting type fan blade transport semi-trailers refers to the fan blade transport vehicle equipped with hydraulic lifting device, which is mainly aimed at the problem of fan blade transport in mountainous areas. Under the condition of parallel road, the fan blade lies flat for transport. In the case of very small turning radius in mountainous areas, the height of the transported articles is increased by lifting devices (generally 5-10 meters high), and the length of the whole vehicle is shortened to bypass the obstacles.

The wind turbine blades transport vehicle, 35 m, 42 m, 45 m, 56 m hydraulic steering wind turbine transport vehicle, 16 m -17.5 m pull-out type low-level semi-trailer. Mountain blade transport tooling. Fan blade transport semi-trailer, 35 m fan blade transport semi-trailer as the name implies: a kind of vehicle is used for transporting the wind turbine blades. The most important feature of fan blade transport semi-trailer is that it has the function of longitudinal expansion and contraction. Due to the extremely long model, it greatly increases the difficulty of turning. In order to overcome the difficulty of curve running, air fan blade transport vehicle is generally equipped with hydraulic steering system.

　　The maximum length of the pull-out type fan blade transport semi-trailers can reach 50 meters, it is triaxial balance type, remotely controlled dynamic steering, and a mass balance block is installed between the front and rear steel plate springs, which can change the deflection of the front and rear steel plate springs in the same amount and balance the force on the front and rear axles. Its total length is 460,000/(17.5﹡22﹡6.5)X3000X1810m, which can be completely pulled apart. The bearing capacity is designed according to 80 tons. The beam height is 550 mm and the width is 300 mm. The beam is designed as the buckle box type, the side beam is 250 mm I-beam steel, the lowest loading surface is 850 mm, the car base plate is 4# floral plate, and the tire is 11.00R-20.

　　This model is specially designed for transporting wind turbine blades and can be extended and retracted up to 44 meters. Due to the length of the cargo itself, it has greatly increased the difficulty of turning. In order to overcome the difficulty of driving in the curve, the rear axle is used, and the rear axle is matched with the power station. At the same time, considering the stability requirements of the goods, the rear axle simultaneously uses its own developed suspension system, which cleverly solves the predictable difficulties in the load. This fan blade vehicle adopts the secondary stretching for 23 meters and rear pulling for 5 meters to ensure that it meets the total length of 44.15 meters; the biaxial steering system is used, and it is equipped with small hydraulic station, and is manually controlled to realize steering, with the maximum rotation angle of 35 degrees; the plate spring is placed downward. The platform is low, the longitudinal beam can draw freely and has good trafficability.
