Abstract
Bei einem selbstgetriebenen Rammbohrgerät (1) mit einem rohrförmigen Gehäuse (2), einer Schlagspitze (5) und einem Sender (9; 11) zur Laufrichtungskontrolle läßt sich die Richtungsstabilität auf einfache Weise dadurch verbessern, daß das Gerät mit einem in Vortriebsrichtung (7) weitestmög lich vorne angeordneten Sender (9; 11) versehen ist. With a self-driven ram boring machine (1) with a tubular housing (2), an impact tip (5) and one Transmitter (9; 11) for checking the direction of travel can be Improve directional stability in a simple way by that the device as far as possible with one in the direction of advance (7) Lich front transmitter (9; 11) is provided.
