Abstract
A suction lifting device for lifting and laying a layered plurality of individual slabs, bricks, stones and the like in unison to provide an exterior paved surface of a road, walk, roof or the like. A plurality of vacuum pucks are supported by the vacuum plenum of a frame through flexible tubular members which operably engage a similar number of slabs or bricks and move them in unison to a preselected and configured location. The frame is carried by a supporting means and a load-bearing member which can be mounted on a self-propelled apparatus.
