Recently, the 6000 ton steel structure corridor of the C-tower project at the Shenzhen Bay Super Headquarters Base was lifted and closed at an altitude of 119.15 meters, achieving millimeter level integration of the new landmark of the twin towers in the Greater Bay Area corridor. The C-Tower project is a super high-rise twin tower structure, with the east and west towers closely connected by an asymmetric complex corridor with upper supports and lower hangers. The corridor has four characteristics of "super span, super weight, super height, and super precision": the maximum span of the corridor is 78 meters, the maximum lifting weight is about 6000 tons, comparable to the total weight of 4000 family cars, and the overall lifting height is about 120 meters, equivalent to the height of a 40 story ordinary residential building, with precision control reaching millimeter level. The Shenzhen Bay Super Headquarters Base faces Hong Kong across the bay, gathers global headquarters, and creates a world-class coastal living room, which is the fulcrum of influence in the Guangdong Hong Kong Macao Greater Bay Area.
