Equipment profile

Built around the project configuration

The SANDVIK Dino DC420Ri is a crawler-mounted surface top-hammer rig for construction, quarry and infrastructure drilling. Its wide oscillating carrier, articulated boom and full radio control provide a stable platform for 51–76 mm holes across urban and uneven worksites.

An 18 m² drilling coverage area reduces repositioning between holes, while the optional three-rod carousel supports continuous drilling to approximately 14 m. The 14 kW RD414 rock drill, onboard flushing air and Stage V diesel configuration form a focused package for drill-and-blast contractors.
