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.
