The invention relates to a lifting system for a decorative block, and belongs to the technical field of bridge construction. Comprising a frame body system; the lifting device comprises two lifting units, each lifting unit comprises two lifting assemblies, and each lifting assembly comprises a winch installed on the frame body system; the pulley block comprises a steel wire rope, a fixed pulley block and a movable pulley block, one end of the steel wire rope is connected to the winch, and the other end of the steel wire rope winds around the fixed pulley block and the movable pulley block; and in the lifting assembly of one lifting unit, the steel wire rope is fixed to the movable pulley block, and in the two lifting assemblies of the other lifting unit, the two steel wire ropes are connected after winding around the reversing fixed pulleys correspondingly. Four-point hoisting and three-point balancing are achieved through the four winches and the pulley blocks, so that hoisting of the special-shaped decorative blocks is balanced and stable, the cutting number of the special-shaped decorative blocks is reduced, the hoisting frequency is reduced, and hoisting safety is guaranteed.
