The invention relates to the field of chimney construction, and discloses a hoisting method for dismounting central drum circles of hydraulic mould lifting devices. The method comprises the followingsteps of symmetrically arranging four support beams at the top of a chimney, arranging a backward pulley block on the inner side of each support beam,respectively arranging four hoisting machines fora corresponding support beam and mounting hoisting machine electric circuits; stabilizing a central drum circle by utilizing a chain block, and building an aisle for the constructors to walk to the central drum circle; lifting the steel wire ropes of the hoisting machines and fixing the steel wire ropes at corresponding hoisting points of the central drum circle after the steel wire ropes pass through the backward pulley blocks; dismounting a radial spar of a mould lifting device and a derrick and loosening the chain block which stabilizes the central drum circle; and carrying out trial hoisting on the central drum circle by utilizing the four hoisting machines, and after the trial hoisting, carrying out synchronous hoisting by the four hoisting machines so as to lower the central drum circle to the ground. According to the method, convenience is brought to the mounting/dismounting construction of a hoisting system, the construction cost is saved, and the mounting/dismounting period ofthe hoisting system is shortened.
