  1. The multi-function series drill rigs, with full-hydraulic top driving drill head, can be applied in shale gas, coalbed methane drilling, superficial petroleum and natural gas exploration, geothermal and water well construction and construction of engineering hole in mines.
  2. The engineering drill rigs are suitable for large-diameter hole drilling in the constructions of bridge, highway, high-rise building, pile foundation and anti-well drilling, which can be carried out in the quaternary period gravel or hard rock stratum and ground with largest diameter of drilling hole up to 3meters.
  3. The horizontal directional drilling series rigs have the pull capacity from150kN up to 12000kN (the largest in the world), which be applied in laying power cable, telecommunication cable, thermodynamic pipeline, gas pipeline and water supplying and drainage pipes, and other gravity pipes which have to cross river bed, highway, bridge, building and other constructions.
  4. The traditional spindle series and full hydraulic crawlers core drill rigs, with the drilling capacity to the depth from 100 to 4,200 meters (328 to 13,776 feet), can be applied in solid mine bed exploration drilling, engineering geological and underground water exploration, mine gallery ventilation and water discharge tunnel drilling. These application can be further described as:
  (1) HXY series as well as their improved products, HYDX series and HCR series drill rig, which are used in geological exploration drilling with the drilling depth from 100 meters to 4200 meters;
  (2) MD series crawlers type and HMC series truck-mounted type coal bed methane drill rig, used in shadow layer oil and gas drilling, oil well repair and ultra deep core drilling;
  (3) GQ series engineering drill rig, which are suitable for foundation pile drilling in bridge, road and building with the drilling hole dia. from 0.8 meter to 3 meters;
  (4) FDP series horizontal directional drill rig, used for underground pipe construction (including power cable, telecommunication cable, heat pipeline, gas pipe and water supply & drainage pipe) with trenchless technology, the pulling force is from 150 KN till 7500 KN.
