Abstract

Apparatus for taking paving elements from a store of such elements, moving them over a placing position and placing them successively onto the subsoil. In one preferred form the apparatus comprises a fork-lift truck having a mast, a jib carried by that mast, swivel means permitting the jib to be swivelled about an upright swivelling axis, a trolley adapted to run along the jib, elevator means for raising and lowering the load carrier, and the arrangement being such that the load carrier can take the paving elements from the store irrespective of the swivelling position of the jib. In a second preferred form the arrangement is such that the load carrier having a plurality of suction apertures to engage respective paving elements can take the paving elements as they have passed an aligning device for a simultaneous alignment of a plurality of roughly aligned paving elements.
