device to align the liegendschwellenteile a powered ausbaueinheit, particularly a support shield

摘要

the invention relates to a device for the orientation of the liegendschwellenteile support shield od.dgl. whose walking base is arranged between the liegendschwellenteilen.erfindungsgemu00e4u00df is a ausrichtvorrichtung envisaged, which druckbeaufschlagung of eingescherten schreitzylinders the bergestou00dfseitigen ends of the liegendschwellenteile press against each other, so that a jamming and blocking the walking base is avoided.
