Warm congratulations! The world's tallest piling vessel, "Tiejian Daqiao Zhuang 1," equipped with the Yongan YC-80 hydraulic piling hammer, has been successfully delivered.
Major national projects join forces, setting new records for Chinese intelligent manufacturing.
On March 31, 2026, the world's tallest piling vessel, "CRCC Bridge Pile 1," successfully completed its sea trial and was put into operation in Nantong, Jiangsu Province, marking a significant step forward for my country's offshore construction equipment in the world's leading ranks. Notably, this "offshore behemoth" utilizes the YC-80 hydraulic piling hammer, independently developed by Yong'an Machinery, as its core operating equipment. This signifies the deep integration of domestically produced high-end piling machinery with a world-class construction platform, providing a "Chinese solution" for cross-sea bridges and deep-sea wind power construction.
World-class platform: Number one in three indicators globally
The delivery of "CRCC Bridge Pier 1" represents a significant breakthrough for China Railway Construction Bridge Engineering Bureau in the field of marine engineering. According to public reports and sea trial information, the vessel has broken several world records.
- Ultimate parameters: 130.5 meters in total length, 40.8 meters in width, and 156 meters in pile frame height. It is currently the world's tallest pile frame, has the largest pile lifting capacity, and operates in the deepest water (approximately 70 meters).
- Intelligent operation: Equipped with a DP dynamic positioning system and a "DP + mooring" dual positioning mode, it can achieve centimeter-level accurate positioning even in severe sea conditions with winds up to level 7 and wave heights of 2 meters.
- Application prospects: With unlimited navigation area dispatch capability, it will directly serve major "Belt and Road" projects such as the Salvador Bridge in Brazil, as well as the construction of next-generation deep-sea wind power pile foundations.

This signing is not merely a simple supply and demand procurement, but a deep strategic partnership between a "national heavy equipment" enterprise and a "hidden champion," marking an upgrade of their cooperation from "project-based" to a "community of shared destiny across the industrial chain." Yongan Machinery's ultra-large tonnage piling equipment breaks the overseas monopoly, further streamlining the overall construction solution from "equipment to piling." For Yongan Machinery, obtaining long-term strategic certification from a central state-owned enterprise is the most valuable certification for its brand.
Core component: Yong'an YC-80 hydraulic pile hammer
As the power core of this "super piling vessel," the Yong'an Machinery YC-80 hydraulic piling hammer is not making its debut in a mega-project. It has already demonstrated its robust capabilities of "high energy, high reliability, and deep-water adaptability" in projects such as the Hangzhou Bay Railway Bridge.

The YC-80 is Yong'an Machinery's flagship product, breaking the foreign technological monopoly. With a maximum impact energy of 1360 kilojoules, it is specifically designed for large-diameter deep-water pile foundations. Its unique cylindrical marine sealing structure and anti-corrosion technology make it perfectly suited for the 70-meter ultra-deep-water operation environment of "China Railway Construction Bridge Pile 1," solving the sealing problem of traditional equipment in complex sea conditions. Furthermore, this project is based on the long-term strategic cooperation between Yong'an Machinery and China Railway Construction Bridge Bureau. The two parties have established deep mutual trust in national-level projects such as the Pingtan Strait Railway-Highway Bridge and the Shenzhen-Zhongshan Bridge.
A powerful alliance: From "equipment manufacturing" to "engineering services"
The "CRCC Bridge Pile 1," equipped with the YC-80, represents not only the installation of equipment but also the implementation of an integrated solution combining "intelligent vessels and high-end equipment." Yong'an Machinery, a national "Little Giant" enterprise specializing in specialized and innovative technologies and a drafter of industry standards, boasts 40 years of experience in piling machinery R&D, with its products applied in over 80 countries and regions worldwide. This collaboration will significantly improve utilization rates during construction windows in strong tides and deep waters, providing international clients with more efficient and lower-cost piling services. Simultaneously, this represents the ultimate recognition from the "national bridge-building team" of a "piling expert," with both parties upholding the banner of complete domestic production and independent control for "super projects."
Conclusion
The joint debut of "CRCC Bridge Pile 1" and Yong'an YC-80 is a microcosm of China's leap from an "infrastructure powerhouse" to an "infrastructure superpower." Yong'an Machinery will continue to uphold its mission of "Endless Pursuit of Security for the World," injecting even stronger "Chinese power" into global marine infrastructure construction.
