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

The day before yesterday, Zhejiang Hopson Hoisting purchased the world's first 9-bridge 4,000 tonsAll-terrain cranesSAC40000T The first crane was successfully completed in the 200,000 kW wind power project in Pingchuan, Baiyin, Gansu Province.

The 6.25MW wind turbine 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, it is a bit overkill to use SAC40000T, and it is the reason for choosing itUnrivalled flexibility of the Nine Bridges。

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

Du Weihui, the project leader, said: "Because of site constraints, it is difficult for cars to enter and put in the ten bridges, and only this nine bridges can meet them. ”

In addition to the advantages of size, the assembly and transition efficiency of the SAC40000T also made the construction party full of praise:

• The assembly speed is fast，It only takes an hour for the left and right overheads to be fully loadedZhang Jie, the person in charge of the equipment, said: "This is our first time to install, and the next time it will be faster, absolutely within an hour." ”
• Strong weight-bearing transition abilityCombined with different wind farm terrains, a variety of transition modes are provided.The heaviest can be with full arms, full legs, main winch and over-lifting transitions。 In this SAC40000T, he carried the whole leg, the first and second 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 position, which greatly saved the disassembly and assembly time of the equipment between the transitions.
• High work efficiency: The hoisting time of the 5th tower is 14 minutes, and the cabin hoisting is completed in 19 minutes.

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

The first hanging performance of the SAC40000T,Sun Lei, general manager of Zhejiang Hopson Hoisting CompanyThe review says: "This 9-axle belt boom is very flexible in the mountainous transition, and this time the seat is so small, it only took 4 hours for the branch to group the car. Its humanized design is really good, reducing a lot of time, especially the over-up assembly, 2 over-up only took an hour. There is also a slotted design of the pull plate, which can be connected by one person, which greatly saves assembly time, and the other is to synchronize these with a super mast and a healthy one, such a large car, so high efficiency，No.1”。
