Abstract:
A cutting apparatus suitable for creating tunnels and subterranean roadways includes independently pivoting supports that each carries 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.
