The invention discloses a groove-disengagement-preventing device for a steel wire rope on an upper rack of a gantry crane lifting device. The groove-disengagement-preventing device comprises two end frames fixedly arranged on the left side and the right side of side plates of the upper rack respectively, and a middle frame fixedly arranged on the upper portion of the part between the two side plates of the upper rack. The groove-disengagement-preventing device can effectively relieve the friction between a steel wire rope and a handrail and lower the strength of friction subjected by the steel wire rope, and the abrasion, caused by the handrail, on the steel wire rope is relieved; the failure rate of the handrail is reduced, and ordinary maintenance and equipment failure shutdown frequency is reduced; the groove-disengagement-preventing device can be dismounted into multiple independent parts at will, apart from a wear-resistance block which is relatively prone to damage, other parts are not prone to damage, and therefore maintenance is convenient and the maintenance cost is reduced.
