Because the rainy season is rather long in this area the heavy rains and typhoons can easily affect the project which brings great difficulty to construction.This paper researches technology for large hoisting machines of super-high-rise buildings from tower cranes replacing selection layout and installation technology of super-high-rise buildings.The removal causes of inner climbing tower crane are analyzed. Moreover the replacing technology of tower crane is introduced.After the tower crane replacing the construction speed is more greatly accelerated and many of the safety hazards for original tower crane are eliminated.
