The "first hanging" completed the first hanging, and the SAC40000T high-altitude lion dance amazed the audience

The day before yesterday, Zhejiang Hopson hoisted and purchased the world's first nine-bridge 4,000 tonsAll-terrain cranesSAC40000T The first hoisting of the 200,000 kilowatt wind power project in Baiyin Pingchuan, Gansu Province was successfully completed.

The 6.25MW fan installed in the project has a hub center height of 120m, a cabin weight of 150t, and a total lifting weight of 180t including spreaders. In terms of lifting weight alone, using SAC40000T is a bit overkill, and the reason for choosing it is precisely because of itUnrivalled Nine Bridges Flexibility Advantage。

The project is a typical mountain wind power plant, with many slopes and steep curves, and the working surface site is very limited:The center of the tower is about 40m away from the cliff edge, and the equipment must complete the U-turn and swing horizontal position in a very narrow space after entering the site, with an operating radius of about 24mIn the words of the on-site personnel: 1m long is not enough.

Du Weihui, the project leader, said: "Because of the site restrictions, it is difficult for the ten-bridge car to come in and not be placed, and only this nine-bridge can be satisfied. ”

In addition to the size advantage, the assembly and transition efficiency of the SAC40000T is also full of praise from the construction party:

• Fast over-assembly，It only takes an hour to complete all the left and right overloadsZhang Jie, the person in charge of the equipment, said: "This is our first time to install, and the next time it will be faster, and it will definitely be done within an hour." ”
• Strong load-bearing transition ability, combined with different wind field topography, to provide a variety of transition modes,The heaviest can be with full arm, full leg, main winch and overtake。 This SAC40000T carried the full legs, the first and second section arms and the telescopic cylinder, successfully challenged the continuous S-shaped sharp bend with a maximum slope of 30% and a length of 2.5 kilometers, and successfully arrived at the machine position, greatly saving the time of disassembling and assembling equipment between transitions.
• High work efficiency: The tower hoisting time of the 5th section is 14 minutes, and the engine room hoisting is completed in 19 minutes.

With the advantage of 9 bridges, SAC40000T successfully passed many S-turn challenges

The day before the hanging, he received Ruixue's baptism and blessings

The performance of the head hoisting of the SAC40000T,Sun Lei, general manager of Zhejiang Hopson Hoisting CompanyThe evaluation said: "This 9-axle belt boom is very flexible in mountain transitions, and this time the unit took only 4 hours to build a car. Its user-friendly design is really good, reducing a lot of time, especially the over-lifting assembly, 2 over-lifting only took an hour. There is also a groove design of the pull plate, which can be connected by one person, which greatly saves assembly time, and in addition, it is to exceed the mast and synchronize these, such a big car, the efficiency is so high，No.1”。
