Description of Down the Hole Drilling Rig (DTH Drilling Rig):
The down the hole drilling rig (short as DTH drilling rig) HC725, which is also called HC725 borehole machines, is extensively used engineering machinery in mining work. The machine can be used for digging holes for water and drilling blast holes on mines. Our down the hole drilling rig (DTH drilling rig) with the features of tracked drilling carriage, self-powered, energy saving, low working noise, great amplitude modulation capacity, using motor and control valve from Germany and Japan, can drill rough and rugged terrains and land forms where other drills are unable to operate. What more, the 10~20m3/min air delivery compressor adapted can ensure hole down 30m or 35m, and drill your well much quicker with an emphasis on safety.
