Recently, on the vast construction site south of Hanoi, Vietnam, a world-class infrastructure mega-project has entered the critical foundation construction phase. As nearly 30 units of Sunward intelligent hydraulic static pile drivers and many other pieces of equipment roll onto the site in formation, this super project—the Vietnam Olympic Sports City, covering an area of more than 9,171 hectares with a total estimated investment of approximately 925 trillion Vietnamese dong—will officially move from blueprints to reality.

As the "world's largest stadium" designed to accommodate 135,000 people in the future, its main stadium—the "Bronze Drum Stadium"—imposes stringent requirements on foundation bearing capacity. Faced with enormous construction challenges, Sunward's "steel legion" has taken on the task with hardcore strength.

Walking onto the construction site, Sunward hydraulic static pile drivers are carrying out cluster operations, creating a spectacular scene. The fleet of hydraulic static pile drivers deployed to the site is dominated by the ZYJ460B and ZYJ680B models. These two products have long been the "ace players" in the field of static pile drivers. Among them, the ZYJ460B is equipped with an efficient heat dissipation system, fully adapting to Vietnam's local high-temperature environment; it adopts a three-point hanging side pile structure with a large installation area, small side pile spacing, and high piling force. The ZYJ680B is equipped with a high-pressure, large-flow pump and a highly integrated monolithic multi-way valve, featuring high efficiency and high reliability.
