A suction lifter comprises a suction cup to be placed against a fixing surface and having a deformable suction disc, the suction lifter being designed for forming a hollow space subject to a partial vacuum between the suction disc and the fixing surface, wherein the suction disc is arranged between the suction cup and the fixing surface, wherein the suction cup further has a circumferential cup rim surrounding the hollow space, and wherein a circumferential supporting area of an upper side of the suction disc facing the cup rim is supported against the cup rim under a vacuum condition. The suction cup rim and/or the suction disc rim are provided with projections which under a vacuum condition of the suction lifter and under a shearing force exerted on the suction disc impede a lateral displacement of the suction cup rim with respect to the suction disc rim.
