Abstract

Ein Rammbohrgerät (1) mit einer Dreh-Zug-Umsteuerung, die aus einem in einem rohrförmigen Gehäuse (2) axial verschieb­ baren Schlagkolben (4) und einem dessen Vor- und Rückbewe­ gung durch Überfahren von im Schlagkolben befindlichen radi­ alen Steueröffnungen (6) steuernden, drehbar gelagerten Steuerrohr (15) mit korrespondierenden Steueröffnungen (21) besteht, das ein mindestens zweiteiliges Steuerrohr (15) aufweist, dessen in Schlagrichtung gesehen hinteres, an einen Versorgungsschlauch (17) angeschlossenes Teilstück (16) vom anstehenden Betriebsdruck entlastet und über eine kraftbeaufschlagte, durch Zug am Versorgungsschlauch (17) gegen die beaufschlagende Kraft (33, 34) axial entriegel­ bare Arretierung (35) mit dem Lagerrohr (14) verbunden ist, verhindert einerseits ein ungewolltes Umsteuern und erlaubt andererseits ein Umsteuern unter Druck.
