1.applied in drilling work of GSHPs geothermal hole. 2.full hydraulic power head(to top) drilling rig.

Feature

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 mechannism(China patent number:ZL03222451.6)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 mathod which has the strongpoint of the quickness,convenince,reliability,ect.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 select from import or home well famous products that make the machine have 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 DTH hammer impact and so on.
