Abstract: The present invention relates to crawler vehicles and more particular to track chain suspension mechanisms, which provide for a smooth and levelled operation of the vehicle. The track chain suspension mechanism of the present invention is characterized in having a first and a second track frame, the first frame being suspended to the vehicle by means of a suspension shaft pivotally and slidable mounted to a suspension frame, the second track frame pivotally connected to the vehicle by means of a drive shaft mounted to a drive frame and wherein said first and second track frame pivotally connected to one another by means of a pivot shaft. In its application for concrete path laying machines the track chain suspension mechanism is further characterized in comprising only one idler at the front of the first track frame.

Abstract: Device for realizing surfacing, in general, realizing surfaces that differ in nature, and more especially for realizing concrete pavements. In particular, it concerns a machine for realizing concrete roads, more especially a type of machine where work can be done without lateral formwork, in such way that after the machine has passed, the road is completely finished and that one only has to wait for the concrete to set and possibly seal the expansion joints before commissioning the road.

Abstract: Paving machine, comprising a movable frame with at least one processing device for processing the concrete, extending according to the working width and which consisting of at least two parts which possibly can be displaceable in respect to each other in order to regulate the span of the processing device, wherein the paving machine comprises means which, on one hand, directly or indirectly control the mutual position of said parts, such in respect to the surface to be formed, as well as, on the other hand, allow for an adjustment of the mutual position in function of the thus performed control.

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.
