October eleventh，World's Largest Tower Crane——22000 of Ton-Meter-Class Super Large Tower Crane in Zoomlion Heavy Industry Science and Technology Co., Ltd.（Hereinafter referred to as Zoomlion）Changde Tower Crane Intelligent Factory Heavy Offline，China Railway Construction Bridge Engineering Bureau Group Co., Ltd.（Hereinafter referred to as China Railway Construction Bridge Bureau）。This is the first 10,000-ton meter-class tower crane built by Zoomlion in the world.、After the 20000 of world-class star products such as ton-meter-class tower crane，Another self-breakthrough.，It is also another important achievement in the development of advanced manufacturing in China.，It has continuously demonstrated the leading strength of Zoomlion in leading the global construction hoisting machinery to climb the new peak.。

Zoomlion, the world's largest 22000, tons of meter-class super-large tower crane, successfully delivered offline

Liu Changhai, Deputy General Manager of CRCC Bridge Engineering Bureau，Assistant President of Zoomlion、Huang Jianbing, General Manager of Construction Hoisting Machinery Branch，China Railway Construction Bridge Bureau、Relevant units of the Owner、Relevant leaders of Zoomlion Construction Hoisting Machinery Branch jointly attended the offline delivery ceremony.。

Zoomlion World's Largest 22000 Ton-Meter-Class Super Large Tower Crane Successfully First Hoisted

The 22000 of ton meter-class tower crane delivered offline was jointly developed by Zhonglian Heavy Branch and China Railway Construction Bridge Bureau.，Its rated lifting torque is up to 22000.t·m，As soon as the product is off the production line, it will become the largest tower crane in the world。The maximum lifting capacity of the tower crane is 730 tons.，Maximum independent height 144.6 meters，The maximum lifting height is 400m，Equivalent to more than 600 vehicles at a time..The 2-ton car was lifted to the height of 130 stories.。

“22000 Ton-Meter-Class Super Large Tower Crane Fully Utilizes Digitalization、Intelligent、Green cutting-edge technology，Based on high security、Highly reliable design concept，Let the product reach‘Big’And‘Steady’In the meantime，It also makes the hoisting of products faster.、More accurate”， The person in charge of Zoomlion said.。

Zoomlion World's Largest 22000 Ton-Meter-Class Super Large Tower Crane

According to introduction，Relying on the advantages of digital and intelligent technology of Zoomlion，Safety of the tower crane、Reliability is further improved。Its intelligent control system is industrial grade.、Controller with super high computing power as the core，High-speed communication，Variable frequency speed regulation，294-channel high-precision sensor detection，Fully realize the digital control of the whole machine。Base on multi-source information fusionETIIntelligent control system，The product applies more than 50 intelligent technologies.，Achieve millisecond response、Millimeter level in place，Faster when lifting、More accurate。At the same time，Based on vision、Active Protection Safety Technology of Radar Multi-mode Fusion、Big data tower crane fault diagnosis technology, etc.，Tower crane to achieve global safety。In addition，In order to ensure the anti-typhoon safety of the tower crane in the marine environment，Zoomlion Innovation Bridge—Design Technology of Tower Crane Structure under the Effect of Typhoon Dynamic Load Coupled with Tower，And that accurate calculation of the wind load of the super-high heavy-load tow crane is realized.，Guarantee the bridge tower—Tower crane is safe。

Very large tower cranes are often accompanied by transportation.、Installation and other difficulties。On the structural design of the product，Zoomlion gives full consideration to standardization、Modular、Transportation size and convenience of installation and disassembly，Use the company's independent innovation of section gradient streamline flat-head single-boom technology.、“Eight King Kong”Tower Body Structure Technology of Smoothing from Large to Small、Many patented technologies, such as single pin tenon, extra large standard section technology, etc.，Not only meets the high bearing requirement of the tower crane structure,，But also solves the transportation of large-size structures.、Assembly and disassembly problems。

Offline delivery ceremony site

In addition，Relying on nearly 70 years of tower crane R & D and manufacturing technology accumulation of Zoomlion，And with the help of the world's largest tower crane intelligent factory of Zoomlion.，It takes only 10 months from contract signing to product delivery for 22000 ton meter-class super-large tower cranes.，It has set a high speed for R & D and manufacturing of super-large tower crane equipment.。

After the delivery of the 22000 of ton-meter super-large tower crane,，It will be sent to Nansha District of Guangzhou immediately.，Help build the world's largest span self-anchored suspension bridge——Wanlong Bridge，Used for hoisting steel structure of bridge tower。
