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.

Claims8

Dependent claims

A vehicle for placing paving elements into desired placing positions on the subsoil, comprising:

(a) support means mounted on the vehicle for supporting a store of paving elements;
(b) a generally vertical mast mounted on the vehicle;
(c) a jib;
(d) swivel means for mounting said jib, at a portion thereof, to said mast to provide for an angular displaceability of said jib about a vertical axis over a swivelling range;
said jib extending away from said mast and being located higher than said support means;
said vertical axis passing at least in the proximity of said support means whereby said portion of said jib is situated substantially vertically above said support means irrespective of the swivelled position of said jib;
(e) a trolley mounted on said jib for travel therealong;
(f) a load carrier mounted on said trolley;
and
(g) elevator means operatively related to said trolley for raising and lowering said load carrier for picking up paving elements from said support means when said trolley is in the zone of said portion of said jib and for placing the paving elements on the subsoil into desired placing positions determined by the selected swivelled position of said jib and the selected location of said trolley on said jib.
