A pulley block mechanism for a crane belongs to the technical field of cranes. Comprising a suspension arm assembly, a transmission wheel I, a transmission wheel II, a transmission wheel III, a pulley assembly and a steel wire rope, a transmission wheel I and a transmission wheel II are arranged on the suspension arm assembly; the third transmission wheel is arranged at the lower end of the second transmission wheel through a connecting frame. The pulley assembly is arranged at the lower end of the third transmission wheel, and a steel wire rope is wound and connected among the first transmission wheel, the second transmission wheel, the third transmission wheel and the pulley assembly; the pulley assembly comprises a pulley, a fixing plate, a hook body and a hanging bracket. The fixing plates are arranged on the front and rear sides of the pulley, the upper ends of the fixing plates are provided with hanging brackets, and the lower ends of the fixing plates are provided with hook bodies. The telescopic smoothness of the steel wire rope during use can be improved; the stability of the mechanism can be improved by arranging a supporting rod and a pull wire; the pulley assembly is of a combined structure, and when the part in contact with the steel wire rope is abraded, the split roller can be partially replaced, and the rest part is reserved, so that the replacement cost can be greatly reduced.
