ROCK CUTTING MACHINE

摘要

A rock cutting machine including a boom (11) rotatably mounted at a proximal end to a chassis (13) adapted to be placed adjacent a rock face (14) to be cut. The boom extends from the chassis to a distal end adjacent the rock fac e. A longitudinal boom axis (21) extends between the proximal and the distal en ds of the boom and a cutting device (10) is pivotally mounted about a pivot axi s (20) adjacent the distal end of the boom. The pivot axis enables wrist movement about the pivot axis by a drive mechanism (29) and is offset from t he longitudinal axis of the cutting device (23).
