Abstract:In the construction of sludge treatment and disposal facilities, the integrated large-sized complete equipment is more widely used. The complete equipment generally has the ultrahigh, super-long and overweight characteristics. How to hoist the equipment from the outside to the inside through the window will be the common problem in the construction process of municipal infrastructure. The methods of main and auxiliary hoists to cooperate the passing-window hoisting, and the horizontal transport for handling tanks are used, which provide the successful cases for the integral hoisting of integrated complete equipment from the outside to the inside.
