Abstract: In a device for inserting dowels (2) in the vicinity of transverse expansion joints of freshly laid concrete road surfaces (4), comprising a machine frame (8) supported by traveling mechanisms (6), at least one storage container (10,12) for the dowels (2), a smoothing board (20) resting on the road surface (4) and including slits (24) running in a direction of travel and provided for accommodating the dowels (2), a retaining device (28) for the dowels on the slots (24), and a dowel placing device (32), it is provided that a line conveyor device (40) accepts separated dowels (2) in a section (44) of a bottom or lateral area (48,52) of the storage container (10,12) and delivers the dowels (2) to the slots in the smoothing board (20).

Abstract: A slip-form paver is provided in the form of a tractor (2) including a machine frame (4) having substantially parallel longitudinal beams (8) at opposite ends of which are track assemblies (14). The machine frame (4) includes a base frame (20) and telescopic cross beams (18) located between the base frame (20) and the longitudinal beams (8). An intermediate frame (24) is located beneath the base frame (20) and is selectively vertically adjustable. Two working mechanisms (28, 32) are in transverse relationship to the longitudinal beams (8), and the latter are transversely shiftable to selectively lengthen or shorten the overall transverse working width of the paver.
