For soil investigation HF-44T Hydraulic drilling machine



I.  General

HF-44T Core  Drill,  a  new  type  of  product  with enhanced  capacity,  is  a  kind  of  hydraulic-driven, spindle, diamond-bit, small-diameter core drill with fairly powerful  drilling  force. It is mainly  suitable for exploration  of metal or non-metal solid mineral ore  bed.  It  is  widely  applied  in  core  drill  with diamond  bit  or  hard  tungsten-carbide-tipped   bit and diamond bit in the field of geology, metallurgy, coal mine, hydrological  and engineering  drilling. It can  also  be  used  in  the  fields  of  superficial-zone

petroleum  and  natural  gas  mining,  mine  workings  ventilation  and  water  discharge  tunnel  drilling  as  well  as foundation  pile  construction  in  large  diameter.  It  is  in  reasonable  structure,  light  weight,  powerful  capacity, multiuse, steady performance, high responsibility and high standardization and generalization.
