Against the backdrop of China's landmark cross‑river infrastructure construction, Zhifang supplied the heavy‑duty JMM 60‑ton friction winch for the Zhangjinggao Yangtze River Bridge project undertaken by CCCC Second Highway Engineering Co., Ltd. This high‑power winch unit has been fully completed and successfully loaded for delivery. Designed for heavy‑load hoisting and towing operations on world‑class suspension bridge construction sites, the equipment delivers reliable, high‑capacity traction performance to support key hoisting tasks of this grand cross‑river project.
The JMM 60‑ton friction winch is a heavy‑duty custom‑built hoisting machinery independently developed and manufactured by Henan Zhifang. Built with heavy‑duty welded steel structure, it adopts mature friction‑drum technical solution, featuring large traction force, stable load holding capacity and outstanding anti‑fatigue performance. All core load‑bearing components undergo strict stress‑relief treatment and full‑load factory testing, adapting to the complex, continuous heavy‑duty working conditions of large‑scale bridge engineering. It provides steady and powerful pulling force for steel cable arrangement, component hoisting and on‑site auxiliary construction of the suspension bridge.
The Zhangjinggao Yangtze River Bridge is a world‑class grand cross‑river suspension bridge project. It puts extremely high requirements on the hoisting capacity, operational stability and equipment reliability of winch machinery. As the key hoisting equipment for this project, our JMM60‑ton friction winch undertakes critical on‑site traction‑hoisting missions.
Rooted in sophisticated craftsmanship, Zhifang devotes itself to manufacturing heavy‑duty industrial machinery. Our robust hoisting strength lends solid support to the construction of this landmark Yangtze River crossing project, helping pave the grand transportation passage connecting river and sea.
