The Zoomlion R20000-720 has played a key role in constructing the Shiziyang Bridge in Guangzhou, China.
The Shiziyang Bridge has a main span of 2,180 m and a dual-layer steel truss suspension design. The R2000-720 tower crane, produced by Chinese equipment manufacturer Zoomlion, has a rated lifting capacity of 20,000 tonne-m and a maximum lifting capacity of 720 tonnes.
Zoomlion said the R20000-720 has demonstrated exceptional performance under extreme conditions, such as strong winds, high humidity, and heavy loads. It has successfully overcome the risks of working at heights, stringent construction standards, and complex construction challenges.
Prior to its deployment at the Shiziyang Bridge, the R20000-720 was used in constructing the Ma’anshan Yangtze River Rail-Road Bridge, the world’s first three-tower cable-stayed bridge with dual main spans exceeding 1 km, and the world’s longest steel truss cable-stayed bridge.
