Towering structures are usually of imposing height, heavy weight and poor bending and torsional rigidities. Hence, their block erection is a technology-intensive cours. Traditional manual control can hardly meet the requirements of the overall process and guarantee its safety. The combination of computer technology with conventional hoisting techniques is applied to the block erection process of towering structures to do the process study of the hoisting system first of all, and to acquire data with instruments and devices according to the process study so as to aid the decision-making and process control of block erection, to realize automatic execution of emergency measures and to guarantee the safety in the course of hoisting.
