HJG-W850A DTH Drilling Rig:
 HJG-W series drilling rig which is a versatile internal combustion-driven crawler hydraulic drilling rig, which is designed and manufactured carefully to meet the high requirements for the users. To essure the stability of the rig's performance, key components are imported pieces. The rig can meet the different geological environments geothermal projects, the exploitation groundwater, hydrogeological exploration, pile construction and 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 times of the traditional rotary drilling. Cutting drilling or cone drilling 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.
