DEVICE FOR DRILLING HOLES AND/OR SLITS
A device is proposed for drilling holes and/or slits in the vertical and horizontal direction, in particular for drilling holes and/or slits in a stone block. The device comprises a self-propelled crane bridge (2) which runs on tracks and is of full-gantry, half-gantry or bridge design, the support pillars (3, 4) being of variable length. The crane bridge is provided with at least one traveller (9) on which height- and direction-adjustable carriages (11) and drilling tools are fitted.
