Abstract (en)

The internal cross-section and inner contour of a ground structure, such as a channel, is processed and enlarged by the equipment involving a milling tool (9) fitted on a support (1) on a beam arm (7). The support has rollers (19) for movement into the cross-section being processed. The beam arm (7) is linked to the support cardanically around a horizontal pivot axis (6) and around a further pivot axis (8). The linkage point of the arm is adjustable as to height.

Abstract (de)

Die Erfindung betrifft eine Einrichtung zum Bearbeiten und Vergrößern des lichten Querschnitts bzw. der Innenkontur eines Erdbauwerks, z. B. eines Kanals, mit einem Fräswerkzeug (9), das auf einem im zu bearbeitenden Querschnitt positionierbaren Träger (1) auf einem Auslegerarm (7) gelagert ist, wobei der Träger (1) Rollen (19) zur Abstützung und zum Verfahren in dem zu bearbeitenden Querschnitt aufweist. Optimale Arbeitsbedingungen können dadurch erreicht werden, dass der Auslegerarm (7) um eine horizontale Schwenkachse (6) und um eine weitere Schwenkachse (8) kardanisch am Träger (1) angelenkt ist und dass der Anlenkpunkt des Auslegerarms (7) höhenverstellbar ist. <IMAGE>
