►Application
HFWJ-150Q drilling rig is a kind of full hydraulic power head (top drive) multifunctional crawler drilling rig. It can be applied in construction of big tonnage stress anchoring hole for hydro power station, railway, highway, drainage hole and geologic calamity fathering for landslide prevention and rock collapse.
►Features
● The great rotary torque of the drilling rig makes the application wider, the borehole speed faster, the accident disposal capability better and drilling work efficiency higher.
● Extension mechanism in the output spindle of top drive power head protects drilling tools effectively.
● 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.
● The hydraulic clamp & wrench device enormously decreases the assistant time and also reduces the intensity of operating work.
● The rig is crawler mounted, which makes the machine move easily.
● Most of hydraulic elements are selected from world famous brand products in order to achieve high reliability and performance stability.
● It can be used by various drilling methods, such as: Non-cycle liquid dry auger drill DTH hammer drill in rock layer by air Mud circulation drill in sand soil layer DTH hammer with tube drill in broken rock area by air
● HFWJ-150Q crawler drilling rig has level system( drill arm) is able to adjust mast in different angle and height without moving drilling rig. It also can working for anchoring drilling in deep foundation basis.
● HFWJ-150Q drill rig can install with jet grouting device in order to drill enlarge head anchoring work. height of level during the drill work.
