Now, no matter you pass by grasslands, mountains and plains, you see a lot of wind turbines. You are particularly curious about how such a big thing is transported. Later, you know that there was a trailer specially transporting wind power blades. Xiaobian was really stunned by this mode of transportation. Let's take a look at how wind power blades are transported.

Most wind turbines are huge. With the development of technology, large and even super large wind turbines are emerging. It is very common that the blade length exceeds 50m and 60m. How are these blades transported?

Almost all these blades are installed in windy places on the mountain, and the transportation process is very difficult. How can they be fixed on these heavy transport vehicles without falling off.

Next, let's take a look at how the 59 meter long blade is fixed on the car.

One fan blade is 59 meters long, so two cranes are required to lift it at the same time.

The car transporting the fan blade is also a special car. The hole on the big wheel is used to combine with the fan blade.

The bottom of the fan blade is a bolt combined with the hole on the special vehicle.

Fan blades began to combine with special vehicles.

The bottom of the fan blade is a bolt combined with the hole on the special vehicle

It fits perfectly.

It's ready for transportation.

In order to effectively solve the problem of difficult passage of blades in climbing sections and turning sections, a special device for mountain road transportation (special blade lifting vehicle) is used for secondary transportation of blades in domestic blade transportation in recent years.

The device is used to control the blades of the transport blade truck, so as to make the blades lift, swing and rotate during transportation, avoid obstacles (trees, mountains, wires, etc.) on the way, and realize that the blades can avoid obstacles to the greatest extent during transportation.

The device is hydraulically controlled to make the wind blade rotate 360 degrees. The wind blade can rotate 360 degrees through the lower slewing bearing and annular slide. The maximum opening angle of the wind blade is 60 degrees through the expansion and contraction of the oil cylinder (calculated from the landing in front of the wind blade tip).
