Abstract (en)
[origin: US4787812A] A self-propelled apparatus for lifting arrays of paving stones has a mobile arm one end of which carries a support for a polygonal assembly of suction cups having axially and angularly movable bellows which attract the paving stones of an array during transport. The support further carries directional jaws which are adjacent to the sides of the polygonal assembly of suction cups and are movable relative to the support to rearrange the paving stones of an array if the distribution of paving stones departs from an optimum distribution. The jaws are moved out of the way before the suction cups deposit the paving stones of an array so that a freshly deposited array can be placed into immediate or close proximity of the previously deposited array or arrays.
