Qatar, the host country of the 2022 World Cup, recently announced good news: the roofing of Lusail, the main stadium for the 2022 World Cup, has been completed with the assistance of 8 TC8039-25 unsupported large-tonnage tower cranes from Zoomlion. Since early 2017 when the project first started, Zoomlion's tower cranes have withstood the test of extreme weather, and efficiently solved construction problems one after another. During the roofing construction, a 2,300-ton main cable-net was stretched 66 meters above the ground, and successfully docked to the steel structure. The successful completion of this challenging project created another benchmark for the construction in “Belt and Road” countries.
