CMM2-33 hydraulic bolting jumbo is built for rock reinforcement in underground coal mines. It's especially suitable for bolting on rocks with strength smaller than f-8. Working together with a production drilling jumbo, this rock bolting rig is used for drilling holes for placing rod bolts and cable bolts. In addition, setting up temporary roof supports provides adequate protection to operators. The mining equipment features high working efficiency, easy operation & maintenance, and stable operation.
