• Target on the face of the TBM provides strict line and grade with laser system (customer supplied).
• Cutter head can be accessed from the front of the TBM and the face of the bore for ease of obstruction
removal, changing the cutter head and to perform routine maintenance, all while underground.
• Torque wings provide an anti-roll function.
• Equipped with a methane gas detection system.
• Standard cutter heads: Dirt, carbide and sand shelves.
• Optional closed face attachment is available for unstable ground conditions.
