Z15 Tower is a super high-rise building located at the heart of CBD in Chaoyang District,Beijing,it will be the tallest building in Beijing.the west side of the project is opposite to Beijing international trade building(the tallest building at the moment),total height of the building is 528m, and planning to be the headquarter building of CITIC. The project start on 12th September,2011, the main structure will be completed at the end of 2016,and the whole project will be completed in 2018.It was invested by CITIC, and it’s estimated total investment reaches 24 billion RMB.
Z15 tower core construction adopts KATTOR JFP system.The main parts applied in this project are: tower crane supporting system,PLC control system and hydraulic control system.
Supporting system contains three supporting layers,on the 1st and 2nd supporting layers there are supporting cylinders(100T),lateral wheels and telescopic cylinders(50T),on the 3rd layer use screw jacks(35T);Hydraulic control system and PLC control system provide powers and realize all cylinders synchronous actions,and also real-time monitor the load condition,all of them ensured the stability of tower crane during construction and jacking up process. The project construction time was greatly decreased by adopting KATTOR JFP system.
