How is the 140m high fan tower made?

Everyone is no stranger to wind turbines, we often reported in the past, what blade manufacturing ah:

Blade transport :

lifting

Shared a number of articles, and even discussed why there are 3 blades and not two blades and so on

But did you notice who was standing behind the blades: Mr. Canister. It also has a temper, a little bend down is enough for us to suffer:

It can be seen that the straight waist of the tower is very important.

Once we shared

Xugong 4000 tons crawler crane

It will have a diameter of 14.4 meters, a height of 118 meters and a total weight of 1,680 tons

Wanhua Yantai Industrial Park propylene tower crane installation

righted

These super-long, tube-shaped giant pieces

Give me a misunderstanding

It has always been considered that the fan tower is also a similar operation

Once formed, once straightened

Let's take a look at the hoisting process of the 140m tower cylinder, from which we can understand how the 140m tower cylinder came to be:

See

140 meters is not directly formed

It's part by part

(The original Xiaobian idea is how naive ah)

Add to it paragraph by paragraph

The final piece is 140 meters high

So this is what it looks like

That's the problem again

How did a length of tower barrel come into being?

In fact, it's also connected

Weld together

Look at how it's made

Originally, the steel plate was rolled into a cylinder by a plate winding machine

And then welded together to form a tower

Weld steel flanges to the ends of each tower section

The interior of the tower is assembled into a section of tower barrel

Several sections of the tower were carried over the mountains

Across great rivers

To a windy place

Then lay a foundation and erect the first column

And then there's the steps that we saw before we started

One by one, it grows into the "Yao Ming" of the fan industry.

One of the most critical stages is the winding process of the tower

After all, the steel plate is very thick

It's a little hard to roll into a cylinder

Let's watch the next video

This process is not only used on towers

Other large pieces with rings are rolled in this way

Roll into a cylinder and then weld

Winding process

Very intuitive

Done.

That's it

140 meters of fan tower barrel with human wisdom

And our store of knowledge

Grew taller together
