Description

It applies to construction of big tonnage stress anchoring hole for dam of water power stations, railways, highways, drainage hole and geologic
calamity fathering for landslide prevention and rock collapse.
1.The great rotary torque and long feeding stroke distance of the drilling rig make the speed of borehole faster, the disposal capability of accident better and efficiency of drilling work higher.

2. Extension mechanism (Chinese patent number: ZL*******1.6) in the output spindle of top drive power head protects drilling tools effectively.

3. The gearshift mechanism of top drive power head adopts the hydraulic shift method which has the strongpoint of the quickness, convenience, reliability, etc. of the gearshift.

4. The hydraulic clamp & wrench device enormously decreases the assistant time and also reduces the intensity of operating work.

5. The equipment is mounted on the track chassis with the turning platform mechanism which makes the moving and walking more and more convenient.

6. The principal hydraulic elements are all selected from import or home well famous products that make the machine have a stable, reliable and durable performance.

7. The drilling rig is suitable for a variety of drill technique and methods, such as the rotary drill, auger drill, air drive DTH hammer impact and so on.
