ABSTRACT Self-propelled apparatus for lifting arrays of concrete, clinker brick and natural stone components of paving sets, com- prises a mobile arm and a suction lifter including a support carried by the arm and a polygonal assembly of suction cups which depend from the support. Each cup includes a bellows movable angularly and axially independently of the bellows of each other suction cup into engagement with a component of a set. The assem- bly has a plurality of lateral sides and directional jaws are movably mounted on the support adjacent to all sides of the assem- bly. The jaws are moved against the components of a set which is about to be lifted by the suction cups so that the jaws rearrange the components of an array where the distribution of components deviates from a desired distribution and the jaws move away from the rearranged components before the suction cups release the rearranged components of the set.
