Abstract

1. Cutter-shield driving mechanism with driving cutters driven forward by a thrust mechanism, there being a piston/cylinder unit (40, 42) attached at one end (38) to each driving cutter (10), characterized in that to the other end of the piston/cylinder unit (40, 42) a supporting member (46) is attached for engagement with a supporting frame (26), and that means (56, 62) are provided to lock the supporting member (46) to the supporting frame (26) so as to resist compression and tension loads.
