Abstract: A concrete paving machine (1) for leveling poured concrete (2) is horizontally extendable in both length and width, as well as vertically adjustable for screening concrete masses of varying dimensions. The concrete paving machine is driven on tracks (12) and is further provided with extendable pressure cylinders, which connect a pivotable arm (16) to a fixed support on a side part of the paving machine, in order to position the endless track (12), to stradle the concrete mass being leveled.

Abstract: A concrete paving machine for leveling concrete having a frame and at least one dowel apparatus carried by the frame. The at least one dowel apparatus is movable along a working width of the concrete paving machine in a direction perpendicular to a paving path. The at least one dowel apparatus includes a vibration device and a dowel distribution device. The dowel distribution device comprises a series of longitudinal members having L-shaped profiles. Each longitudinal member forms a predetermined pattern of recesses wherein the series of longitudinal members are slidably arranged so that in an unlocked position, the recesses of each longitudinal member are aligned so as to permit distribution of at least one set of dowel bars. In a locked position, each longitudinal member is arranged to so that the recesses are misaligned so as to prevent distribution of at least one set of dowel bars.
