A construction machine () with a machine frame () and lifting columns () carrying crawler track units (). The lifting columns () include consoles () coupled in pairs to the machine frame () by articulations () and a coupling rod (). The mutual distance of the articulations () on a console () is of a length and/or the coupling rod () is of a shape that, when the crawler track units () swivel between limit positions of a swivel gear (), the coupling rod () maintains a distance to the articulations () facing the machine frame and/or to the lifting columns () over a swivelling angle range in excess of 90&#xb0;, starting from the working position. The swivel gear () effects both the steering and the swivelling movements respectively in and from a transport position () to the working position and back.

Construction machinery and pivoting device

In a slip-form paver comprising a tractor () consisting of a machine frame () telescopable at least transversely to the traveling direction, with working means being mounted thereto, where at least one of the working means is displaceable along a longitudinal guide () across the entire working width transversely to the traveling direction, characterized in that the longitudinal guide () for the working means as a predetermined length and is supported at the machine frame () for free displacement transversely to the working direction without adjustment to a certain working width.

Slip form paver

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

Device for inserting dowels into freshly laid road surfaces

In a slip-form paver comprising a machine frame ( ) including longitudinal beams ( ) extending in parallel to the working direction, and transverse beams ( ), and comprising a chassis ( ) including a plurality of truck assemblies ( ) adjustable in height by means of a lifting column ( ) and carrying steerable tracks ( ) maintaining the plane of the machine frame ( ) in a predetermined position, it is provided that a slidable traverse member ( ) is mounted to at least one transverse beam ( ) of the machine frame ( ) in a manner allowing for displacement transversely to the working direction, and that the front truck assemblies ( ) are mounted on the slidable traverse member ( ).

Slip-form paver

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

A device for smoothing a concrete paving surface including a machine frame that defines a predetermined working width perpendicular to a predetermined direction of travel of the machine frame, and a carriage system for moving the machine frame in the predetermined direction of travel. The device also includes a transverse smoothing portion carried by the machine frame for smoothing concrete paving across the predetermined working width that has two transverse structures with adjacent ends and remote ends and an articulating portion for connecting together the adjacent ends of the transverse structures. The device further includes a longitudinal smoothing portion for effecting longitudinal smoothing of concrete paving, and a moving portion for moving the longitudinal smoothing portion along the transverse structures over the entirety of the predetermined working width.
