D series features:

HJG-D Series integrated hydraulic DTH drilling rig has a wide range of applications in constructions of metallurgy, mine, building material, railway, hydro-electricity, national defense and earthmoving engineering. The hydraulic power drives the crawler travel, rod rotation and push boom lifting erection. The compressed air drives impact drilling and hole-flushing, the air pressure ranges from 1.05 to 2.4 Mpa. Equiped with HJG high air pressure DTH hammer, the rig can drill the vertical or oblique holes which ranges 90-254mm diameter and maximum 30m depth. Parts worldwide procurement, computer optimum design and power & load adaptive system, actualize the power-pump-load adaption and ensure the low energy consumption, high performance and high reliability of machine.


(1) Intergrated structure.

Drilling system, air compressor and power engine system with compact structure and reasonable layout. The air compressor and main pump system are controlled with single motor unit, enable the rig with favourable flexibility, efficiency and movability.

(2) Flexible operating system, safe and comfortable cab with AC.

Drill frame angle adjustable, meet the requirement of multi-directiond drilling holes.

Boom supports wide range of working area, drilling rig can complete multiple holes operations at a position, significantly improved work efficiency.

Drill arm outstrectched, factors of drilling stem vibration and dust discharged from the operating environment for the machine stability and the impact of significantly lower than conventional rigs, increase machine life and drilling accuracy.

(3) Floating chassis

High reliability of driving mechanism, swift moving, fast lifting, significantly improve efficiency of production. Adopting floating moving chassis, enables the rig to work in the rugged workplace.

(5) Reliable shock absorption

Independent design shock sub below the power head, efficiently increase the performance during drilling, prolong the life-span of the power head.  

Auto block-prevention mechanism can life the drill stem automatically when the stem got stuck.

Hydraulic systems, pneumatic systems are both adopt the separated power-driven, energy-saving efficiency obviously.
