The invention relates to a concrete paving stone multi-layer laying method with a mobile stacker truck and a laying device which carries with it laying units stacked in a number of layers on pallets and always removes the upper layer of interlocking stones, pivots it and sets it down in the sand surface. The laying arm, which is fastened on two struts or support construction on the roof, can be a rigid jib with a sliding piece, a telescopic boom or an articulated boom. The actuation can take place mechanically with oil or air pressure. By means of a rotary device, the jib is intended to reach all positions, being pivotable by 360 DEG . Actuation with levers on or near the driver's stand is expedient. The main advantage of the method is that the existing technology of the stacker truck is supplemented with two struts for receiving the load and crane booms are fastened thereon with laying tongs. Since a number of laying units are transported along at the same time, the lost time to fetch individual laying units, which is the case in many other methods, is eliminated. <IMAGE>
