The Power of Role Models - Liu Zhiyan



Liu Zhiyan, one inPiling machineryHe is a senior expert who has been intensively cultivated in the field for more than 20 years. He has a master's degree and has been committed to the research and development of piling machinery products since joining Sany in 2004.

With the pursuit of technological excellence and unremitting exploration of innovation, he has won wide recognition in the industry, and won the third prize of Beijing Science and Technology, Beijing Youth Post Expert and other honorary titles, is an indispensable backbone in the development of Sany pile crane.

When I first entered Trinity, the seeds of my dreams quietly germinated

In 2004, Liu Zhiyan joined the vigorous development of Sany with a fiery dream of mechanical engineering and an infinite vision for the future. At that time, Sany was in a period of rapid growth, with opportunities and challenges coexisting. For him, who has just stepped out of campus, this is not only a workplace for a party to display his talents, but also a broad stage for him to realize his self-worth and let go of his life dreams.

"Sany is like a magnetic field full of magic, attracting everyone with lofty ideals to move forward bravely." Whenever he recalls his first entry into the Trinity, Liu Suo's eyes always shine with excitement. He knows that in this dynamic and competitive land, only continuous learning and innovation can stand out. He devoted himself to the research and development of piling machinery products, from consolidating the theoretical foundation, to in-depth analysis of the performance of each component, to repeated testing and debugging, he used practical actions to interpret his persistent pursuit of technology and full of love for work.

Twenty years of perseverance, growing up with the pile driver, sharing the same fate

More than 20 years have passed, and Liu Zhiyan has experienced the whole process of Sany's rise to become a world-renowned construction machinery giant. At the same time, he has completed a magnificent transformation from a young graduate to an experienced technical expert and manager.

"It's not easy to work at Sany for more than 20 years, what makes you so persistent?" In the face of such a question, Liu replied without hesitation: "It is the broad platform provided by Sany, the corporate culture that is deeply rooted in the heart, and the pride and sense of belonging that grows together with Sany." ”

What Sany has given Liu is far more than just a job, but also a strong sense of belonging and a full sense of achievement. Here, he was able to display his talents and realize his self-worth. The vigorous development of Sany made him feel the fruitful results brought by his hard work, and also strengthened his determination to contribute to Sany.

SR220R: A Legend of Rock from Scratch

In his more than 20 years of product design career, he has handled many projects, but the SR220R rock rotary drilling rig is undoubtedly the most shining and proud star in his memory.

Before the advent of SR220R, Sany's rotary drilling rig was mainly used in soil construction, and once it encountered hard rock formations, the construction efficiency would be greatly reduced. In order to break through this technical bottleneck and expand the application field of rotary drilling rigs, Liu led the team to resolutely embark on the research and development journey of rotary drilling rigs. This is destined to be an exploration full of hardships and challenges. From the fine optimization of pressure and torque, to the optimization and selection of drilling tools, to the in-depth study of rock crushing mechanism, Liu and his team started almost from scratch and accumulated experience bit by bit. They consulted extensive literature, visited a number of construction sites, actively exchanged and discussed with experts and scholars, and carried out experiments and improvements day and night.

"Of course, it has also experienced repeated failures, rectification and failure, and it took two years to finally bring it to market." Liu recalled, with a hint of emotion in his tone. Every failure means that countless days and nights of hard work have come to naught; Every rectification means that everything has to start anew and meet new challenges. However, Liu and his team did not back down, and they always believed that as long as they persevered, they would achieve the ultimate victory.

In the end, after countless tests and improvements, the SR220R rock rotary drilling rig broke out of the cocoon and successfully came out. This drilling rig can not only easily control a variety of complex rock formations, but also significantly improve the construction efficiency, which has won high praise from our customers. The success of SR220R has not only brought considerable economic benefits to Sany, but also injected surging vitality into the development of the entire rotary drilling rig industry.

Build dreams with ingenuity and innovate the future

Liu Zhiyan's story is the epitome of Sany's countless strugglers. They create quality with ingenuity, drive development with innovation, and contribute to the development and growth of Sany with their hard work and sweat. With their efforts, Sany will continue to write a new brilliant chapter and make greater contributions to China's manufacturing to the world.

Liu Zhiyan's experience tells us that the road to success is never smooth sailing, and only after experiencing countless failures and setbacks can we finally achieve success. Persistence, innovation and responsibility are the keys to success. In the days to come, we believe that Liu Zhiyan will continue to lead Sany rotary drilling rig with his professionalism and enthusiasm to continue to innovate and make breakthroughs, and contribute more to the development of China's construction machinery industry!
