The invention discloses a device for preventing a steel wire rope for fixed pulleys of a bridge crane from jumping from a slot, and aims to provide a device which is simple in structure and can effectively prevent wear to fixed pulley shafts and jumping-out-of-groove accidents due to lateral force and elastic force born by a steel wire rope. The device comprises rollers which are mounted on webs on two sides of a crane trolley, located above fixed pulley blocks and are perpendicular to the winding direction of the steel wire rope, and the distance between each roller and the fixed pulley blocks is 3-9 mm.
