Dichtungen für neuen Gesteinsbohrhammer von Atlas Copco ermöglichen längere Wartungsintervalle

(PresseBox) (Weinheim/Bergstraße, )
Für Atlas Copco, den weltweit führenden Anbieter von Gesteinsbohrhämmern, hat Freudenberg Sealing Technologies ein neues Dichtungssystem entwickelt. Dadurch konnten die Wartungsintervalle einer neuen Maschinengeneration im harten Untertage-Einsatz verdoppelt werden. Die Serienproduktion der
COP MD20 im schwedischen Örebro ist nun angelaufen.

Bis zu 140 Mal pro Sekunde trifft der Bohrmeißel mit einer Kraft von 25 Tonnen auf die Gesteinsoberfläche. Seine Aufgabe: 80 Löcher zu bohren, in die anschließend die Sprengladungen kommen, mit denen Versorgungstunnel im Untertage-Bergbau oder im Straßenbau in den Fels gesprengt werden. Angetrieben wird der Meißel von einem Gesteinsbohrhammer, im Englischen als „Rock Drill“ bezeichnet.
