[PRNewswire] Building in the "Bermuda of the East": Zoomlion's Tower Cranes
Complete Lifting Operations for the World's Longest Road-rail Cross-sea Bridge
(PINGTAN, China, Dec. 16, 2019 PRNewswire=연합뉴스) Over 35 self-developed high-end tower cranes produced by Zoomlion (01157.HK) completed lifting operations for the Pingtan road-rail bridge project, the world's longest road-rail cross-sea bridge. As the lifting equipment provider, Zoomlion set a new benchmark in metocean engineering with customised machinery for what is described as the "the world's most difficult" bridge construction project.
Zoomlion's high-end equipment series was shortlisted by China Railway Major Bridge Engineering Group Co., Ltd. (MBEC), the contractor of the project. The crane series includes the super-large D1100-63V tower crane, TC7035-16 hammerhead tower crane, and flat-head TCT7015A-10E tower crane.
Pingtan Bridge, a 16.32km long bridge project including three cable-stayed bridges, crosses the Haitan Strait in the East China Sea. The strait is often referred to as the 'Bermuda of the East' for its severe metocean conditions. Strong winds, storm surges, undercurrents and huge waves pose unique operational challenges seldom seen on construction sites.
The Pingtan Bridge project utilises significant quantities of construction materials including over 300,000 tons of steel and 2.66 million tons of cement, which is enough to build 8 Burj Khalifa towers. Zoomlion took on this challenging task as the main lifting equipment provider.
Despite the harsh environment and tight schedule, Zoomlion's tower cranes provided continuously stable operating performance and high efficiency to ensure the project was completed on time.
To combat gale-force winds in the region, Zoomlion's research team created a series of technical solutions. Zheng Changming, Product Director Large Flat-arm Tower Crane Platform of Zoomlion's Research Institute, said, "We re-designed the configuration of the D1100-63 to ensure wind resistance. The upgraded D1100-63 tower crane can be jacked up when exposed to gale-force 7 winds and can be safely operated up to gale-force 8 which is 20.7 meters per second. In extreme cases, it can withstand wind speeds of up to 46 meters per second, which is the equivalent of a category 14 typhoon."
"We also added a cyclotron sector to the D1100-63 tower cranes while keeping the length of arm unchanged to ensure the crane can rotate under extreme weather conditions," added Zheng.
The Pingtan Road-Rail Bridge project is the first cross-sea bridge to be constructed under a complex metocean environment and is built to withstand winds of gale-force 10. The bridge is expected to open to traffic in 2020.
