In October this year, the super strong typhoon "Rainbow" landed at the Zhanjiang River in Guangdong. The maximum wind force reached 15 levels. The Zhanjiang Hengda Oasis was built with six tower cranes of different manufacturers. After the typhoon, there was only one Dongguan. The Yixin tower crane stood still, and the remaining five tower cranes installed in the high-rise buildings were all blown down.
