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.
Claims10
A cutting apparatus suitable for creating tunnels or subterranean roadways and the like comprising:
- at least one arm pivotally mounted to the apparatus and arranged to pivot in an upward and downward direction;
- at least one arm actuator arranged to actuate pivoting movement of the at least one arm about an arm pivot axis;
- a rotatable cutting head mounted at the at least one arm, the head being rotatable about a head axis oriented to extend substantially transverse to the arm pivot axis;
- a drive motor unit for supplying a drive power;
- and
- a cutter gear drive train coupled between the at least one arm and the cutting head for transmitting the drive power to the cutting head, wherein the drive motor unit includes a plurality of drive motors, each drive motor being coupled to the drive train and supplying a portion of the drive power, wherein the cutter gear drive train has an axis of revolution substantially aligned with the head axis of the cutting head, the cutter drive train being arranged to transmit radial and normal forces from the cutting head to the at least one arm.
