摘要: A shield advancing machine, comprising cutting tools (15) rotatably supported on cantilever arms (13, 14) being rotatable around an axis approximately extending in advancing direction and being swivellable in transverse direction to this axis, has a carrier (4) which is guided and supported in axial direction of the shield (1). A rotation drive (22, 33) for a rest (9) of the cantilever arms (13, 14) is provided on the carrier (4), and the cantilever arms (13, 14) as well as their swivel drive (16, 17) are linked to the rest (9).
