    Abstract: A tunnel driving apparatus with a cylindrical shield in which is mounted a cutting head which serves to detach material from a working face to effect driving of the tunnel. The cutting head is driven by a shaft which extends through a thrust ring to which a circular array of hydraulic rams concentric with the axis of the shield is connected. This thrust ring, which supports the cutting head, is connected through universal joint assemblies to guide members which slidably locate in guideways extending longitudinally of the shield.
