CUTTING APPARATUS USING A PLURALITY OF DRIVE MOTORS

摘要

A cutting apparatus (100) suitable for creating tunnels and subterranean roadways. The apparatus comprises at least one arm (121) pivotally mounted to the apparatus and adapted to pivot in an upward and downward direction; at least one arm actuator (122, 130) to actuate pivoting movement of the at least one arm (121) about an arm pivot axis (401); a rotatable cutting head (128) mounted at the at least one arm (121), the head (128) rotatable about a head axis (402) oriented to extend substantially transverse to the arm pivot axis (401), a drive motor unit (125) for supplying a drive power; and a cutter gear drive train coupled between the drive motor unit and the cutting head for transmitting the drive power to the cutting head, wherein the drive motor unit (125) comprises a plurality of drive motors, each drive motor being coupled to the drive train and supplying a portion of the drive power.
