From China's first 100-ton truck crane to the world's largest all-terrain crane，From following and imitating to independent research and development，Chinese cranes from“Chaser”Become“Frontrunner”。Between role transitions，It is the leading scientific and technological research of equipment manufacturing represented by Zhonglian Heavy Branch.，It is also inseparable from the hard work and dedication of skilled workers.，They are in batches“The most important weapon of the country”A powerful pusher of birth。

Long Weiguo, the skilled master of Zoomlion Construction Crane Branch, is the one.“Push hands”A member of.。From an ordinary crane debugger to a national technical expert，Long Weiguo has been sticking to the front line of equipment commissioning for 21 years.，To interpret and practice Zoomlion with practical actions“Craftsman”Spirit。

Practice with great concentration

In the eyes of outsiders，The debugging work is tedious and boring.。As far as Long Weiguo is concerned，Commissioning is a process that gives life to the crane.。“You will find，After adjustment，The micro-motion of the car、Reliability、The stability is all there.，The whole car seems to come alive.。” Long Weiguo said。

Long Weiguo's understated debugging work is actually extremely difficult.。All the technologies involved in the crane，Debuggers should be familiar with everything.。Know about electricity、Understand hydraulics、Can drive a car、But also have the operation qualification to get on the bus and so on.，Many aspects are involved.、The field is wide，So，In the early years, there was a great shortage of talents capable of doing this type of work in the industry.。

So，When just nowLong Weiguo, who entered Zoomlion, was assigned to a debugging post with a very high threshold by virtue of the first place in the training examination.，He grasped the opportunity firmly.。Practice hard during the day，Study theory at night.，Take the trouble to consult the master about the technical experience and skills of debugging.，It took only six months to master all the operational skills.，It also won the first place in the company's debugging skills competition.。

Accumulate over time，Long Weiguo has mastered all kinds of professional skills of debugging.，Practiced a strong basic skills.，From an ordinary debugger to a mature one、Comprehensive technical backbone for commissioning，Engage in the field of large tonnage and super-large tonnage。

Overcome difficulties

Debugging is a process of crossing the river by feeling the stones.，To some extent, it is more about finding problems and solving them.。

“When I first entered the industry.，The largest tonnage crane we make is 50 tons.，Large tonnage is monopolized by foreign enterprises.，As our company continues to innovate，Our new crane products are constantly on line.，The tonnage is getting bigger and bigger.。”For more than ten years，Long Weiguo has witnessed the vigorous development of cranes in China.，But in the field of debugging,，The challenges behind it are also growing.。“In the process of our conventional products moving towards super-large tonnage，In fact, many things have not been touched.，There is no textual reference.。Similar to super-lift technology、Horizontal bar bolt technology、Wind power arm technology and so on，These things have never been seen before.。” Long Weiguo said frankly。

There are no technical parameters，There is no mature experience for reference.，Long Weiguo experimented repeatedly.、Grope。Especially in the face of the current unique structural design and control system.，Digitized by、Automation、Super heavy equipment supported by intelligent technology，It directly leads to the increase of debugging difficulty and workload.，Long Weiguo relied on his aggressiveness.、Stubborn、Toughness and drilling，Led the team through countless“Heart abuse”All night long，Overcome difficulties step by step，At each strength test、Continuous learning from stability and reliability testing、Analyze the reasons、Summing up experience、Optimize the process，Break through the difficult problems in the field of cranes one after another，Finally, a complete set of standardized commissioning process is solidified.，It provides an excellent experience for later generations.。

Continuous breakthrough

From 2001 to 2022，Long Weiguo has debugged more than 40 items.“The first new product”，Climb up and down the turntable nearly a thousand times.，Touch、Tens of thousands of parts adjusted，In the day-to-day grind，Long Weiguo is willing to be ordinary but unwilling to be mediocre.。“Model worker of Hunan Province”“National Young Professionals”“National technical expert”……He took root in the front line of debugging for 21 years.“Medals”。In the face of hard-won honors.，Long Weiguo is always indifferent.，He used to say：“I'm just doing my job.。”

Excellent vocational skills、A conscientious attitude、The spirit of innovation，Long Weiguo has been entrusted with important tasks by the company several times.，Follow the company to participate in 2015、Preparations for live broadcast of three military parades in 2017 and 2019、On-site hoisting and shooting work，Excellent completion of Skyhawk with the team.、Erection of Universal Hawkeye、Equipment security、The task of shooting the parade.。

June 2022，Long Weiguo participated in the 2400-ton all-terrain crane with the largest tonnage in the worldZAT24000HSuccessfully delivered，It marks that Zoomlion has once again broken its own world record of the world's largest 2000-ton all-terrain crane.。For this new achievement.，Long Wei Guo Yong“Ideas build the future”To evaluate。In his opinion，These six words bear the connotation of Zoomlion as an equipment manufacturing enterprise.，It also reflects the height and vision of Zoomlion's corporate culture.。“2002，Our country can not build a truck crane of hundreds of tons.，Until now，Zoomlion and other domestic brands，Constantly set new records.，It has once again built the world's largest tonnage all-terrain crane.。The so-called thought builds the future，It is to focus on the future before the future has arrived.、Plan for the future、Achieve the future，This is Zoomlion.。”

Today，There are several big characters on the wall of the crane debugging platform of Zoomlion.——“Make the best crane”。Long Weiguo said，This is what they're doing.“The largest in the world”New challenges after：From“Max”To“Best”。They are going all out，“From the beginning，Cangshan is like the sea”，To the future。
