Sandvik DS311 is the most compact mechanized rockbolter on the market. Its unique rockbolting concept delivers the best ratio of rockbolt length to drift height.
Sandvik DS311 is a one-man-operated electro-hydraulic rockbolter for rock reinforcement in underground mines with small and medium cross sections. The operator works from supported ground while protected under a FOPS / ROPS-certified canopy structure. Mechanization of the bolting process ensures efficient, constant and durable rockbolt integrity. Built from proven and reliable components, Sandvik DS311 is designed for high availability. Its core is the reputable Hydrastar 200 rockdrill, which enables a fast performance. Versatility is also one of the rockbolter’s key characteristics. Sandvik DS311 can install most common rockbolts ranging in length from 1.5 to 3 meters (5 to 10 feet).
