Abstract

A cutting apparatus suitable for creating tunnels and subterranean roadways includes independently pivoting supports that each carry a respective, independently pivoting arm and a rotatable cutting head. Each cutting head, via the supports and arms, is configured to slew laterally outward in a sideways direction and to pivot in a vertical upward and downward direction. The supports and arms are mounted on a linear moving sled carried by a main frame.
