The Sandvik three-arm jumbo is an electrohydraulic jumbo designed for fast and precise drilling, in tunnels and cave excavation. DTi jumbos are fast, precise and intuitive. They allow high quality excavation, with low operating costs, thanks to several features: iSURE tunnel management program, iDATA intelligent control system and robust arms. To further improve the excavation process, remote access via WLAN can be chosen, enabling internet-based data transfer, as well as online measurement, while drilling (MWD).
