China has taken another big step on the road to scientific and technological independence!
According to the South China Morning Post, a well-known international media in Hong Kong, recently, China's first 5,000-ton super-large hydraulic cylinder in Changzhou, Jiangsu Province officially rolled off the assembly line, which is the world's largest and strongest hydraulic cylinder, and its advent marks a major breakthrough in China's hydraulic technology in the field of marine engineering infrastructure.
This major progress not only fills the gap in domestic technology, but also breaks the long-standing monopoly of foreign companies in this field.

This giant hydraulic cylinder has a maximum thrust of 5,000 tons, which is equivalent to pushing 1,000 adult African elephants! According to CCTV, this hydraulic cylinder is independently developed by China and is currently the largest and strongest product of its kind in the world, reflecting China's independent innovation ability in the field of high-end marine engineering equipment manufacturing.
The cylinder, which is mainly used in offshore infrastructure, has a length of 28 meters and a diameter of almost 2 meters, which is equivalent to the height of a ten-story building. It will provide the core power for a 150-metre-long piling vessel under construction, which is expected to be commissioned by the end of this year for the construction of the Hangzhou Bay Cross-Sea Railway Bridge, which will soon be the world's longest sea-crossing high-speed rail bridge.
According to CCTV, Chinese manufacturers have long lagged behind the world's leading companies in the design and manufacture of large hydraulic cylinders, especially key components such as sealing rings and corrosion-resistant materials.
But that is rapidly changing. This super-large hydraulic cylinder made in Changzhou, Jiangsu Province means that China has achieved "the domestic substitution of extra-large and ultra-long hydraulic cylinders and the independent control of core technologies", laying a solid foundation for China's marine engineering.
Developed by China Communications Construction Corporation (CCCC), the cylinder is an important step towards China's maritime power. As the mainland continues to promote the development strategy driven by science and technology, the high-end equipment used in the construction of marine engineering infrastructure is gradually localized and no longer controlled by others.
In addition, this technology will be widely used in many fields such as large-scale offshore drilling platforms and the construction of wind power generation facilities in the future. This innovative achievement, jointly completed by a number of domestic new materials and intelligent manufacturing enterprises, demonstrates China's teamwork ability and scientific and technological innovation level in the field of high-end equipment manufacturing.
In July, Beijing also set up an offshore engineering innovation alliance that includes experts from large state-owned enterprises and private enterprises such as China Communications Construction Co., Ltd., as well as experts from universities with strong academic strength, such as Tsinghua University.
According to the People's Daily, the alliance's main work focuses on the construction and operation of offshore transportation infrastructure, offshore wind and solar energy, coastal bay protection and restoration, island and reef engineering construction and ecological protection, and deep-sea pipeline installation. These measures will undoubtedly further promote the technological self-reliance of the continent in the maritime field.

Behind the successful research and development of this super-large hydraulic cylinder, it reflects the leapfrog development of Made in China in the field of high-end equipment. First of all, the success of this hydraulic cylinder means that China has reached the world's leading level in ultra-large-scale hydraulic technology, which has significantly improved the competitiveness of the mainland in the field of offshore engineering.
In high-tech engineering projects such as offshore piling and deep-sea energy development, having strong domestic equipment not only reduces dependence on foreign supply chains, but also lays the foundation for the mainland to have more voice and market share.
Secondly, this breakthrough reflects the significant improvement of China's technological accumulation and innovation capabilities in the field of intelligent manufacturing and new materials. In the past, due to high technical thresholds and complex materials, Chinese manufacturers have been restricted by others for a long time in terms of sealing technology and corrosion-resistant materials.
The successful launch of the hydraulic cylinder is the result of the cooperation of many domestic enterprises in the fields of new materials and intelligent control, which represents that the overall strength of Chinese manufacturing is gradually catching up with the international leading level.
In recent years, China has actively pursued the strategy of scientific and technological self-reliance, especially in the maritime field, focusing on the localization of high-end equipment, which is crucial for safeguarding the mainland's national security and economic interests.
As a key piece of equipment, the successful localization of offshore hydraulic cylinders not only represents the improvement of manufacturing technology, but also means that the mainland can promote the construction of marine engineering more independently, whether it is bridges, wind power, or deep-sea resource development, it can rely on the core technology of independent innovation.
It is worth mentioning that the application of this hydraulic cylinder is also closely related to the national new energy strategy. With the increasing global demand for renewable energy, wind power, as a representative of clean energy, has become a key area for the development of many countries.
In the construction of wind power generation facilities, especially the piling construction of deep-sea wind farms, strong equipment support is required. This hydraulic cylinder independently developed by China will provide strong technical support for the future construction of deep-sea wind power, and help the mainland to be at the forefront of the world in the field of new energy.
From a more macro perspective, these breakthroughs made in China will also play a positive role in promoting the implementation of the "Belt and Road" initiative. The localization of high-end equipment such as offshore engineering hydraulic cylinders will enable the mainland to have more technical advantages in international engineering contracting and help enhance the competitiveness of Chinese enterprises in the global market.
Especially in infrastructure projects in coastal countries, Chinese enterprises will be able to provide more cost-effective and technical solutions with self-developed high-end equipment, further enhancing the global recognition of "Made in China".
[A little summary]
Overall, the advent of the 5,000-ton super-large hydraulic cylinder is an important breakthrough in the field of marine engineering equipment in China.
This not only broke the monopoly of foreign technology and realized the localization of key equipment, but also demonstrated the comprehensive strength of the mainland in intelligent manufacturing and new material technology.
With the use of hydraulic cylinders, the technical level and independent capabilities of the mainland in the fields of marine infrastructure construction, deep-sea wind power, and offshore drilling platforms will be significantly improved.
This series of achievements is not only an important symbol of China's manufacturing moving towards high-end and getting rid of foreign dependence, but also a solid step for the mainland to achieve the goal of becoming a maritime power.
In the future, we have reason to believe that relying on scientific and technological innovation and independent research and development, China will achieve breakthroughs in more fields and help the mainland move from a manufacturing country to a manufacturing power.
