Abstract

1,197,581. Percussive tools. COAL INDUSTRY (PATENTS) Ltd. 12 March, 1968 [14 March, 1967], No. 11940/67. Heading B4C. An excavating machine comprises a chassis 2 mounted on a self propelled base 4, a boom 24 movably mounted on the chassis and an hydraulically actuable percussive tool 32 mounted on and movable with respect to the boom. The percussive tool is provided with a cutter 42 which, when pressed against a rock face, starts the percussive action automatically, the tool being mounted on a platform member 34 which is pivoted on the boom and movable in a vertical plane by means of a ram 36; the tool is moved along the platform by means of a ram 38. The boom is movable in vertical and horizontal planes by means of rams 28 and 30 respectively and rotatable by means of a motor 31. The base may be "walked" along the ground by system of rams or by crawler tracks driven by hydraulic motors. The chassis may be slidably mounted on the base.
