The ST-30 hydraulic tunnel machine is designed for sub-horizontal consolidation, for half-section or full-section drilling, up to a maximum height of 6.98 m from ground level.

A special accessories kit lets you use the equipment also for vertical or inclined drilling, for traditional consolidation or the invert of the tunnel with a stroke of 14 m and a max diameter of 114 mm.
This feature means full-range use of the equipment for the best investment and operating flexibility.
