CMD50 CBM/CSG Drilling Rig

CMD50 hydraulic drilling rig is specially designed for vertical drilling operations in coal-bed methane(CBM, CSG) and water well, with air& mud drilling techniques. It’s especially suitable for drilling water well with 1200m depth, and CBM drilling. Telescopic mast, tilting top drive, the rig can be trailer mounted, truck mounted or crawler mounted in accordance with drilling conditions.

Features:

●the most popular working mode: tilting top drive trip in& trip out.

●Telescopic mast: 9m rods can be pulled up by the long stroke of top drive.

●Mechanical direct drive mud pump with truck mounted, improve work efficiency

●Premium hydraulic components from Europe / US.
