At first sight, Zheng Longzhi was slightly thin, wearing a clean white shirt and a pair of rimless glasses, giving a bookish impression that repairing loaders requires strength and experience.
And he looked so refined as if he had nothing to do with oil and tools.
As soon as he entered the workshop, beside the tire of a heavy loader more than one person high, he firmly grasped the handrail with both hands and lightly jumped up with his body, acting coherently and skillfully.，The reporter just realized that don't just look at the outside.，He is a real expert.
From initial fitter to training instructor、Senior technician，From obscurity“Screw”To an admirable country.“May Day Labor Medal”Winner，Zheng Longzhi has been sticking to the production line for more than 30 years，Step by step“Become a skilled person”The road。He is an apprentice with the rank of Gai.，Lao Gai kept calling him before he died.“Teacher Zheng”。For more than 30 years，He has experienced the development of loaders from fuel engines to pure motors.，It also witnessed the rise of Xiamen's construction machinery industry, which innovates and forges the heavy equipment of a big country.。
Zheng Longzhi is the leader of Gai's Labor Model Innovation Studio.。
Grow up
Apply for the major of maintenance electrician
Joined XGMA after graduation
As one of the spirits of Xiamen in the new era, Gai's military rank spirit，It deeply affects Xiamen people.。In the Antarctic research circle，Even foreigners know that there is a great Chinese mechanic named Lao Gai.。
At a sharing meeting.，As the leader of Gai Rank Labor Model Innovation Studio，Zheng Longzhi spoke with deep feeling about the extraordinary journey of his master Gai's pursuit of his dream.。He said with emotion.：“Stick to the ordinary post，Try to do every little thing well.，And create extraordinary achievements in the ordinary.，This is the greatness of my master Gai's rank.，It is also the way to realize his life value and dream.。”
Zheng Longzhi's pursuit of his dream began in 1990, when he failed the college entrance examination and was disheartened to give up school to find a job.
However，A word from his parents changed his direction.：“The family has a daughter，It's better to have a skill”。On the advice of the parents，He decided to choose Xiamen Technical School.（It is now Xiamen Technician College.），Learn a skill，So that they can support themselves in the future.。At the last moment before the end of the school's on-site enrollment.，He successfully enrolled in the major of maintenance electrician.。
Why choose this major?？Zheng Longzhi said frankly，Because of myopia, only the maintenance electrician major has no strict requirements for vision in the major he is interested in. Looking back now,，He sighed with emotion，Choose Xiamen Technical School，Select maintenance electrician discipline，Catch up on the last day of admissions，All this is fate in the dark.，Let him seize the opportunity at the critical moment of development.。
Early 1990s，Xiamen's manufacturing and construction industries are in a period of rapid development.，The demand for skilled talents is extremely strong。When Zheng Longzhi graduated in 1992.，Many state-owned enterprises、Large joint ventures and private enterprises have come to the school.“Rob people”，Including Xiamen Xiagong Machinery Co., Ltd.（Hereinafter referred to as“Xiagong”）。He and two other students in the class chose XGMA together.，And successfully joined the company。
Zheng Longzhi recalled when he first became an apprentice.，Master Gai once told him what to do.：“Skilled workers must be able to bear hardships and stand hard work.、Be persistent、The spirit of innovation，But it is more important to have a high sense of responsibility.。”As an apprentice with the rank of Gai.，He personally witnessed the successful solution of a series of difficult problems in construction machinery.，He was deeply influenced by the master's superb skills and simple disposition.。“Be sure to become a technical expert like Shifu.”The idea of，It is deeply rooted in Zheng Longzhi's heart.。
Zheng Longzhi is inspecting the internal components of the newly finalized equipment.。
Become a useful person
Accumulation of decades of experience
Practice“Look, listen, ask and feel”Stunt
In the workshop of XGMA，A loader of the latest model is being overhauled.。I don't know why，The fault light of the machine is on continuously。Disciple can't find anything unusual.，So he invited Zheng Longzhi to come over.。After simply asking for a few exceptions,，He immediately identified the problem as a radio accessory.。Take the radio down and test it.，Sure enough。
Now Zheng Longzhi has been trained.“Look, listen, ask and feel”Be able to judge the problem of the machine with a few tricks.
Like this“Human Flesh Tester”，It depends on decades of hard work.。First day in class，Zheng Longzhi followed closely behind the master.，Little by little、Learn one move at a time，Start with the basics of wiring。Have you mastered the basic skills?，He began to work hard on the principle of equipment structure.。As long as there is free time.，He crouched over the machine.，Take the design drawing and compare it with the real object bit by bit.，Learn the internal structure、How it works，Learn the causes and judgment methods of equipment failure。
Heavy loaders and cars are built with the same mechanical principles.。Before the launch of the new model，Zheng Longzhi always holds the design drawings.，Compare with various research on automobile principle。As soon as the new machine comes online，He already knows everything about the machine.。XGMA's colleagues said.，XGMA has a state-level technical center.，Most of the designers are senior experts.，But during that time in the assembly shop,，Every research and development of the electrical system should be revised and verified by Zheng Longzhi on the spot.。And the products checked by Zheng Longzhi，The pass rate is 100.%。
Therefore, Zheng Longzhi is also known as“A designer's corrector”It is an important promoter of the company's technological innovation.
2007，Zheng Longzhi is responsible for the after-sales service of 100 loaders exported to Iran.，Due to salt water erosion during shipping，Causing problems with the device's circuitry。He quickly got to the root of the problem.，Put forward the transformation plan，In order to save the delivery time of spare parts，Purchase parts in Iran's major mechanical parts markets。He repaired and optimized the damaged parts.，Finally, the problem was successfully solved.，Lay the foundation for the company to develop the market in Iran，It also provides a design model for the subsequent electrical system design.。
Zheng Longzhi or“Prototype machine”The designer of
2010，He found that the circuit design of the loader had the problem of too long wiring harness.，It wastes materials and is inconvenient to install.，Therefore, he boldly put forward the optimization design scheme.。Due to changes involving the full range of loader products，Designers have different opinions.。With the support of Master Gai，Zheng Longzhi speaks with results.，To modify a machine personally.，And persuaded the designer with a large bundle of extra wire harnesses.，Obtain the approval of technical transformation project。This adjustment is made when the output of the equipment is high.，It can save more than 10 million yuan of material cost for XGMA in one year.。
Zheng Longzhi conceives the technical training of new generation equipment。
