Abstract

1382157 Rock drills TITAN MFG CO PTY Ltd 15 Dec 1972 58103/72 Heading B3C A rock drill comprises a telescopic leg 14, 15, 16, an hydraulic motor 22 for rotating the drill rod 18, a first valve 10 for supplying pressure fluid to the leg, a second valve 11 for supplying fluid to motor 22, and means for controlling the valves. Valve 11 is operated by a Bowden cable 26 and a lever 27, and valve 10 is operated by a twist grip 20. Water for dust suppression and swarf removal is piped to a unit 24, and thence through a passage in drill rod 18 to drill tip 19.
