The invention discloses a novel tower crane variable-amplitude trolley rope breakage prevention protection device, and belongs to the technical field of tower crane construction safety protection. The novel tower crane variable-amplitude trolley rope breakage prevention protection device comprises a mounting frame fixedly connected to a variable-amplitude trolley, a limiting piece I is hinged to the upper end of the mounting frame, a steel wire rope of the variable-amplitude trolley penetrates through the lower end of the limiting piece I, and a limiting piece II is hinged to one side of the upper end of the mounting frame; the limiting piece II is arranged at the lower ends of a horizontal web member and an inclined web member of the cargo boom and is transversely arranged along the cargo boom, the hinging directions of the limiting piece I and the limiting piece II are perpendicular to each other, a U-shaped piece is arranged at the end, close to the limiting piece II, of the limiting piece I, and the top end, close to the limiting piece I, of the limiting piece II is limited by the U-shaped piece; the weight of the ends, away from each other, of the limiting piece I and the limiting piece II is larger than that of the ends, close to each other, of the limiting piece I and the limiting piece II. The rope breaking prevention protection device has the advantage that the reliability of the rope breaking prevention protection device is improved.
