发明名称 Matebjelkeanordning for en fjellboremaskin
摘要 A feed beam for a rockdrill has slide guides along which the rockdrill can slide on the beam, with the working surfaces of the slides being removable and replaceable. The removable slide guides on the beam itself entirely determine the profile of the slide guide, and the rockdrill is supported by the detachable slide guides and by the connections between these slide guides and the feed beam. In a similar manner, the feed beam is located on a support frame of a drill boom or similar component and can be driven along the support frame by a hydraulic cylinder or other similar means.
