The present invention discloses a crane movable pulley apparatus with a rope breaking protection and anti-falling mechanism. The crane movable pulley apparatus comprises: a pulley seat, wherein the pulley seat comprises two pulley seat sandwich plates arranged in an opposite and parallel manner; a pulley, wherein the pulley shaft is arranged between the two pulley seat sandwich plates; and a rope breaking protection mechanism arranged in the pulley seat, wherein the middle portion of each pulley seat sandwich plate is provided with a sliding channel along the longitudinal axis line, both ends of the pulley shaft can be arranged in the sliding channel in a longitudinal sliding manner, the rope breaking protection mechanism is a rope clamping assembly and comprises two rope clamping mechanisms and a transmission assembly arranged in the pulley seat and respectively connected with the pulley shaft and two rope clamping mechanisms, and each rope clamping mechanism is arranged corresponding to a steel wire rope inlet-outlet end of the pulley seat. According to the present invention, when the lifting steel wire rope loosens or is broken, the lifting steel wire rope can be stopped in the pulley seat on the side with no rope breaking, such that the probability of the heavy object falling accident caused by the breaking of the steel wire rope is substantially reduced, and the good safe protection effect is provided.
