Sandvik DS311D is a one-man-operated electrohydraulic rock bolter for rock reinforcement in underground mines with small and medium cross sections.
The operator works below supported ground while protected under a FOPS / ROPS certified cabin structure. Mechanization of the bolting process ensures efficient, constant and durable rock bolt integrity. Built from proven and reliable components, Sandvik DS311D is designed for high availability. Its core is the reputable Hydrastar 200 rockdrill, which enables a high drilling performance. Versatility is also one of the rock bolter’s key characteristics. Sandvik DS311D can install most common rock bolts ranging in length from 1.5 to 3 meters (5 to 10 feet).
