Yan Junling is a renowned figure in the history of Shanghai Port, and his pioneering work has been recognized worldwide. Born on May 24th, 1917, Yan Junling graduated from the University of Science and Technology of China with a degree in Mechanical Engineering in 1941.

In 1945, he joined the People's Liberation Army and was assigned to the Shang Hai District Military District as a mechanic. During this time, he developed a new type of machine tool called the "Wing Breaker", which revolutionized the production process of steel plates and other construction materials.

The Wing Breaker allowed for faster and more efficient assembly of large-scale structures such as bridges and buildings, making it possible to produce more steel at a lower cost than traditional methods. This innovation not only improved the efficiency of the steel industry but also had significant implications for China's economic development.

Yan Junling continued to innovate and push the boundaries of technology during his career. He worked closely with engineers and scientists from all over the world, including the United States, Germany, and Japan, to develop and test various wing breakers before finally selecting the best one for use in Shanghai Port.

In 1968, the Wing Breaker was selected by the Chinese government to be used in Shanghai Port. The Wing Breaker was designed to be both safe and effective, allowing for quick and easy assembly of large-scale structures without the need for heavy equipment or skilled labor.

Today, the Wing Breaker remains an essential part of the steel manufacturing process in Shanghai Port, providing reliable and consistent output at unprecedented levels of speed and efficiency. Its success in the field of engineering and technology has earned Yan Junling international recognition and admiration, and his contributions to the development of modern steel industry continue to be celebrated today.
