HYDX-5A Full Hydraulic Core Drill Rig

The HYDX-5A new model Full Hydraulic Core Drill Rig is developed by H.H. Drill-Tech Drilling Machinery Co., Ltd.
The product description

I. General Introduction

The HYDX-5A new model Full Hydraulic Core Drill Rig is developed by H.H. Drill-Tech Drilling Machinery Co., Ltd. with reference of advanced technique of same kind equipment at home and abroad. The 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

HYDX-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. 


II. Main Performance Parameter of HYDX-5A

The figures in these tables have been calculated, based on field experiences, and may be reasonably expected.

Actual drilling capacity will depend on in-hold tools and conditions, drilling techniques and equipment used.
