Breaking Overseas Milestone: Henan Zhifang's 250-Ton Single-Line Heavy-Duty Winches Power the World-Class Retractable Roof of Vietnam's Trống Đồng Stadium
Henan Zhifang Machinery Manufacturing Co., Ltd. has secured another landmark overseas project. Four sets of self-developed JM250 heavy-duty winches with a single rope pull capacity of 250 tons have been successfully deployed for the retractable roof traction system of Trống Đồng Stadium (VinFast Stadium) in Vietnam. With robust heavy-industry manufacturing expertise, Zhifang empowers the construction of this world-class iconic infrastructure.
Project Profile: A Mega World-Class Sports Complex
Trống Đồng Stadium (Trống Đồng Stadium) is located in the core zone of Hanoi Olympic Sports New Town and serves as a key national infrastructure project of Vietnam. Drawing design inspiration from Vietnam's millennia-old Đông Sơn bronze drum culture, the stadium presents a magnificent silhouette. Planned with 135,000 seats, it will become the world's largest dedicated football stadium upon completion.
The centrepiece of the venue is its 315 m ultra-long-span retractable roof. The total weight of the roof steel structure exceeds 30,000 tons, operating under extremely demanding working conditions:
Extreme local wind loads (basic wind speed: 44 m/s)
High seismic fortification standard (seismic intensity of 8.5 degrees)
Precise, stable and repeated traction of the thousand-ton roof
Such ultra-large span, massive load and stringent safety requirements set top-tier engineering benchmarks for the traction equipment in terms of load-bearing capacity, braking stability and fatigue resistance.
Zhifang Hoisting: 250-Ton Winches as the Core Workhorse
The roof retraction system adopts an advanced hybrid solution combining winch traction and trolley self-drive, with all core heavy-duty traction equipment supplied by Henan Zhifang Hoisting.
The four JM250 heavy-duty winches delivered for this project are specially optimized for high-end overseas infrastructure operating conditions: ✅ Superior heavy-load capacity for thousand-ton roof traction operations ✅ Dual braking protection for zero-risk performance under heavy continuous loads ✅ Wind-resistant, seismic and weatherproof structural design, adapting to harsh outdoor environments in Southeast Asia ✅ Precision welding and full-scale non-destructive testing, fully compliant with acceptance standards for premium overseas engineering projects
From customized drawing design, precision machining and complete machine assembly to full-load testing before delivery, Zhifang Hoisting adheres to strict heavy manufacturing standards. With reliable, safe and efficient equipment performance, the company has overcome technical challenges in dynamic traction for the giant roof and ensures accurate operation of the stadium retraction system.
The successful delivery and commissioning of the four 250-ton single-line winches for the landmark Trống Đồng Stadium project stands as solid proof of Zhifang Hoisting's competence in heavy-duty winches and custom special lifting equipment.
For years, Henan Zhifang Hoisting has focused on R&D and manufacturing of winches, hoist gates and special heavy lifting equipment. Its products serve high-end scenarios including mining, water conservancy, bridge engineering, heavy industrial plants and large overseas infrastructure. The company undertakes custom projects for large-tonnage, high-complexity non-standard lifting equipment.
From key domestic projects to iconic overseas infrastructure, Zhifang Hoisting delivers reliable Chinese manufacturing quality to support high-quality development of global engineering construction.
Moving forward, Zhifang Hoisting will continue technology innovation and quality improvement, further expanding its global footprint and bringing Zhifang's intelligent manufacturing to more international flagship projects.
