The device for picking and transporting components of different size has a gripping casing (1) which comprises a plurality of concentrically arranged, axially movable gripping elements (4, 8, 11). The elements move telescopically relative to each other, and each have a suction opening arranged at the end and connected, according to the working position, with a vaccuum inlet (3). For picking up a small part, only the innermost, smallest gripping element operates. In picking up a middle-size part, the innermost gripping element (11) and the middle gripping element (8) work together, while in the gripping of a large part, the outermost gripping element (4) is additionally actuated.
