The HFDX-5 new model Full Hydraulic Core Drill Rig is developed with advanced technique of same kind equipments at home and abroad. The drill rig has a reasonable design and superior performance. It is easy for operation and maintenance.
Overall Unit Features:
The drill rig adopts full hydraulic driving, tire trail-type. 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 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. TheHFDX-5looks 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 the 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 polluting emission of diesel engine, professional noise reducing design, the drill rig is fully
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.
Field of Application:
HFDX-5 Type Drill Rig is mainly used for inclined and straight holes drilling. It could be used for exploration and prospecting of geology, metallurgy, coal, nuke industry, hydrology and in other industries fields. It is a core drilling rig by using diamond and carbide-tipped bits mainly.
