The Sandvik DL421-7 is an electro-hydraulic long-hole drilling rig for large-scale production drilling inunderground mines.

The rig has been designed for vertical and inclinedplane rings and fans, parallel long production holesas well as long single holes. The 360° rotation andparallel coverage, together with wide tilt angleranges forwards and backwards, make the boomsuitable to various drilling applications.

Instrumentation and data drilling with various auto-mation options allow maximum performance withsuperior drilling accuracy. Proven CAN-based tech-nology on board allows the operator to set the unitfor any rock conditions. It also makes the upgrade ofautomation level easy, and has a fault finding sys-tem, which reduces downtime.

The machine is based on a proven carrier for highmobility. Both drilling and tramming are done fromthe operator's platform.
