By retracting all shields, the overall diameter is reduced by up to millimeters during tunnelling, depending on the machine type. This allows for a flexible reaction to expanding rock and prevents the machine from jamming. With the aid of the gripper unit, the machine can even be retracted completely, if necessary.
