Abstract

Die vorliegende Erfindung betrifft eine Abstützvorrichtung für Baumaschinen wie Hydraulikbagger und dergleichen, mit einem Abstützfuß (1), der schwenkbar an einem maschinenseitigen Tragstück (4), vorzugsweise einem Fahrzeugrahmen oder Chassis, angelenkt ist, und einem Schwenkantrieb (6) zum Aus- und Einschwenken des Abstützfußes (1). Erfindungsgemäß zeichnet sich die Abstützvorrichtung dadurch aus, dass der Abstützfuß aus mehreren Stützschenkeln (2,3) besteht, die nach Art eines Teleskops ausfahrbar aneinander befestigt sind, und eine Feststelleinrichtung (28) zum Feststellen der Stützschenkel (2,3) in zumindest einer Stellung relativ zueinander vorgesehen ist.

The present invention relates to a supporting device for construction machines such as hydraulic excavators and the like, with a support foot (1) which is pivotally hinged to a machine-side support member (4), preferably a vehicle frame or chassis, and a pivot drive (6) for swinging out and of the outrigger foot (1). According to the invention, the supporting device is characterized in that the support foot consists of several support legs (2,3), which are telescopically attached to each other in the manner of a telescope, and a locking device (28) for locking the support legs (2,3) in at least one position is provided relative to each other.
