General Introduction of DF-H-5A Core Drilling Rig
The DF-H-5A Full Hydraulic Core Drill Rig has a reasonable design and superior performance. It is easy to operate and for maintenance.

1. Overall Unit Features:
The drill rig adopts full hydraulic driving, travelling with crawlers itself. The drill head is driven by variable motor with function of two-speed mechanical gear shifts, stepless speed change with an advanced  and simple structure. The rotator is fed and driven with a system connecting the spindle and oil cylinder with chain. The system has the function, if the piston rods of oil cylinder moving one certain distance, the drill head moving will double the distance. The mast could be adjusted within the range of angle 0 to 90 degree for its drilling hole with a low center of gravity and good stability of the overall unit. The rig provides operator with a nice field of vision and wide and comfortable working condition. The rig looks pretty in overall structure and embodies the design thought of people oriented.
1) Reliable Performance
Basing on the guideline of purchasing the critical auxiliary equipment internationally, the diesel engine, the hydraulic pump, the main valves, the motors, crawler reducers and key hydraulic spare parts are all adopted famous brands products at home and abroad.
2) High Efficiency
With big torque, high power unit allocation and with reasonable structure design and advanced operation method and 6 meters(19.7 feet) length of drill rod, all these guarantee the drill rig’s high operation and performance efficiency.
3) Environmental Protection
With lower pollution discharge of diesel engine, professional noise reducing design, the drill rig is suitable for urban operation and performance.

4) Energy Saving
Adopting the advanced load sensitive control technique, the drill  rig has reduced the power consumption and heat generation to the lowest level.
With an elegant outline, compact structure, reliable performance and operation easily, it should be the priority equipment to be selected in the full hydraulic core drill rig of present domestic market.
2. Field of Application
DF-H-5A Type Drill Rig is mainly used for slope and straight holes drilling.It could be used for exploration and prospecting of  geology, metallurgy, coal, nuke industry, hydrology and for other industries fields. It is a core drilling rig by using diamond and carbide-tipped bits mainly.
