Core drilling drilling rig HJG-W series

explorationmultifunctiongeothermal

HJG-W series drilling rig which is a versatile internal combustion-driven crawler hydraulic drilling rig, is designed and manufactured carefully by Changsha Heijmgang Industnal Co... To ensure the stability of the ng's performance. key components are Imported pieces. Maximum clang depth of the rig is up to 900 meters and drilling range is between 105 - 311mm in diameter. The rig can meet different geological environments geothermal projects, the exploitation of groundwater, hydrogeological exploration, pile construction and some other project needs.the whole machine is advantageous with a more powerful engine, bigger output torque. higher working efficiency. flexibility, as well as better stability and multifunction. etc. When DTH hammer is applied on rock drilling In the operation, the crushed gravel Is discharged by high pressure air-flows, and the drilling efficiency is ten limes of the traditional rotary drilling. Cutting drilling or cone dnlling can be operated in the unconsolidated layer, rock and mud discharging. In total, the machine is suitable for drilling in complicated geological conditions.The rig can replace or even equal imported production and whose performance-price ration is more outstanding than latter. Comparing with other competitors.
