Top 10 list of global tower crane manufacturers in 2021，Zoomlion ranks first in the world in tower crane，Zoomlion has topped the list for many times.。Behind the glory，It is the hard work and sweat of countless tower crane workers。Among，34 years of focus on tower crane research and development、Won“National model worker”Title、Yu Lekang, deputy general manager of Zoomlion Construction Lifting Machinery Branch, is a typical representative and outstanding person.。

June 1986，Yu Lekang graduated from Shanghai Jiaotong University with a major in lifting machinery.，Enter the predecessor of Zoomlion——Design engineer of tower crane in Changsha Construction Machinery Research Institute，Since then, it has formed an indissoluble bond with Zoomlion and tower crane.。

“I love Zhonglian，I love tower cranes！”It is a sentence that Yu Lekang often talks about.；“Extreme pursuit of perfection”It's what his colleagues say about him.。His solid professional knowledge、Rigorous style of doing things、Pragmatic Scientific Research Spirit，It is easy to be ingenious not for prosperity.，Be the ultimate person.、Do the ultimate thing.、Become the ultimate karma，It not only helps the development of Zoomlion tower crane，It has also realized its own value.。

Before 2000，The technology of super-large tower crane has been monopolized by foreign countries.。National construction is in full swing，However, those key projects and projects are all imported super-large tower cranes.。“I was very upset at that time.，I firmly believe，China's Tower Crane Technology Needs Breakthrough，First of all, we must break through the design of super-large tower crane.、Manufacturing and other technical problems。”Yu Lekang said。End of 2009，China Railway Bridge Engineering Group Co., Ltd. has put forward the engineering demand for the super large tower crane of 5000-ton and 240-ton.，Technical proposal to be issued by Zoomlion。At that time，The company's largest tower crane is only 63-ton in the 1100-ton class.。“The pressure can be imagined.”。

As the technical director of Zoomlion,，Yu Lekang led the tower crane R & D team to design and discuss the scheme day and night.，It took only eight months to complete the world's largest tonnage slewing tower crane at that time.DDesign, development and manufacturing of 5200，Help Zoomlion Break the International Brand Monopoly of Super Large Tower Crane。

It is with this ultimate spirit.，Yu Lekang led the technical team to make continuous achievements.“The ultimate thing”：Developed the world's longest boom tower crane, which won the Guinness World Records.、World's Largest Tonnage Inner Climbing Arm Tower CraneLH3350 and other world-class star products，At the same time, it has been developed successively.TC5610、TC6012、TMore than 40 tower crane products such as 7020，And the hot market.WSeries、RGeneration series tower crane。2021，Yu Lekang and his team built the world's first 10,000-ton tower crane.W12000，Help Zoomlion surpass itself and create another world record，It also sets up another monument for the development of the industry.。

In addition to constantly introducing new products,，In terms of basic technology research，Yu Lekang led the technical team to achieve many breakthroughs.。He led the team to carry out the extreme working condition test.、Life design、Drone、Research layout of basic core technologies such as digital control，Further enhance the strength of Zoomlion in this field。
