anchor drilling rig

Product Description

TDA*7 drilling rig is one kind of full hydraulic power head (top drive) crawler drilling rig. It is mainly applied in drilling work of GSHPs hole, and also used in drilling the drain hole and large tonnage prestressed anchoring hole of the geotechnical engineering such as the side slope of dam construction, railways, highways, etc.; the guiding hole of high pressure jet grouting in gravel area;the blast hole; the anchoring hole of high buildings deep basement foundation;the anti-floating anchoring hole; the foundational reinforcing hole of interior architecture; the grouting reinforcing hole; the reinforcing hole of road or dam foundation; and the anchoring hole of landslide preventing.

1. Features

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.

1. 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.
2. The hydraulic clamp & wrench device enormously decreases the assistant time and also reduces the intensity of operating work.
3. The equipment is mounted on the track chassis with the turning platform mechanism which makes the moving and walking more and more convenient.
4. 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.
5. 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.
