Sandvik DS312 is a one-man-operated, compact and highly versatile rock support drill with a dedicated screen handler boom designed for fully mechanized rock reinforcement in underground mines with small and medium cross sections.
Features

Independent mesh handler
This mesh handler is installed on its own boom with continuous 360° screen rollover. The mesh can easily be grabbed from the side wall or floor. It allows a safer and faster mechanized meshing process.

Optional instrumentation package
Sandvik Bolting Instrumentation (SBI) and the SB70S instrumented boom combined with data transfer ensure a safer, smoother bolting process as the operator has all valuable information available on the rig’s touch screen.

Optimized working environment
This drill rig offers two modern, ergonomic FOPS/ROPS cabins (standard or low-height option) for maximum operator comfort with improved visibility and reduced noise level.
