Abstract

1374853 Supporting rock drills COAL INDUSTRY (PATENTS) Ltd 13 Feb 1973 [14 Feb 1972] 6690/72 Heading B4C [Also in Division E1] In a mining machine an impact tool 21 is mounted with a rotary cutter head 45 on a self advancing base 3. The tool 21 is mounted at one end of a boom 16 and a slideway 20, on which the tool can be moved by ram 25, is carried on the boom for movement about vertical and horizontal axes by rams 26, 27. The rear end of the boom 16 is pivotally secured to the base for movement about vertical and horizontal axes by rams 17, 18 and the length of the boom can be adjusted by a ram (not shown) mounted within the boom. The base is provided with skids 5 which are movable relative to the remainder and along which the rest of the base can slide. Alternatively a crawler track arrangement could be used. Stay means (Fig. 3, not shown) are provided to anchor the base and comprise pads which can be swung out to the side.
