Wind blade transporter, as its name implies, is used to transport wind power blades. The biggest characteristic of the wind blade transport semi-trailer is that it has the longitudinal telescopic function. Because the model is extremely long, it greatly increases the difficulty of turning.

There is no standard description of the type of semi-trailer for blade transport. There are common wind blade trailers, modular blade transport semi-trailers and lifting blade transport semi-trailers.

• Common wind blade trailers

The ordinary pull-out type blade transport vehicle is similar to the low bed semi trailers, but its girder adopts the buckle box design. The girder adjusts the length of the vehicle through pulling to adapt to the transport of different lengths of blades. It is understood that the pull-out type blade transport semi-trailer can be up to 50 meters.

The gooseneck of the fixed vane at the front end of the wind blade transport semi-trailer can be raised by 82 cm, and under load, by raising the vane, the wheelbase of the trailer can be effectively reduced to a certain extent, the shorter the wheelbase is It is easier when the vehicle is turning.

In addition to the adjustable height of the front gooseneck, the rear tire suspension can be raised by 60 cm. When the road conditions are good, the height can be reduced to shorten the wheelbase, and when the road conditions are bad, the height can be raised to improve the trafficability of the vehicle.

This wind blade trailer can be pulled up to 60 meters long. It is nothing to pull out. The key is that it can lift through the gooseneck of the front fixed vane when it is loaded, and cooperate with the movement of the fixed vane platform at the back. When turning, the wheelbase of the vehicle can be reduced and the turning performance of the vehicle can be improved. If there is an obstacle on the roof, by increasing the wheelbase, the height of the vehicle can be reduced and the trafficability of the vehicle can be improved.

• Modular blade transport semi-trailers

The biggest difference between modular blade transport semi-trailer and ordinary wind blade transport trailer is that the chassis adopts hydraulic axis design, which makes the cargo table of the blade trailer lower and the steering more flexible.

In response to sharp turns, the rear axle of this wind blade trailer can steer about 60 degrees to the left and right. When going through sharp turns, it can effectively prevent the vehicle from rolling and ensure the safety of the vehicle, and it can also save tires to a certain extent.

• Lifting wind blade transport semi trailer

Lift type wind blade transport semi-trailer refers to the air blade transport vehicle equipped with hydraulic lifting device, mainly aimed at the problem of air blade transport in mountainous areas, in the case of flat road, air blade lying down transport. In the case of small turning radius in mountainous areas, lift the height of goods carried by lifting device (generally 5-10 meters), shorten the length of the vehicle to bypass obstacles.

In the process of transportation, the hydraulic control can make the wind blade rotate 360 degrees, the wind blade can rotate through the lower slewing support and the annular slide way to a maximum angle of 360 degrees, and the maximum opening angle of the wind blade is 60 degrees through the expansion and contraction of the cylinder. Counted from the front of the wind blade tip landing on the ground).

These designs are compared with ordinary wind blade transport vehicles, especially for mountain vane transport. Although the lifting blade transport vehicle solves the problem of mountain transportation to a certain extent, it is still very difficult especially when facing extreme curves.

Seeing this, I believe everyone has a preliminary understanding of wind blade transport semi-trailers. Putting so many technologies together, the road adaptability of these wind blade transport vehicles should be very strong.
