KT9C integrated surface DTH drilling rig is efficient and energy-saving advanced drilling equipment which is developed carefully for small and medium opencast mining, quarry and infrastructure construction project. I

1. The overall layout is more reasonable, easy to maintain.

2. Using Cummins QSC8 3-C260-30 diesel engine or Yuchai YCA08280-T300, big Capacity and torque reserve can provide more power support in harsh environments.

3. Hydraulic use a relatively independent multi-pump system, cancel diverter valve, more stable.

4. Equiped 17/17 single-stage high-pressure compression screw system by Dr. Tang Yan, compared with mieda Working pressure interated drilling rig made by other manufacturers, it has an overwhelming advantage.

5. Using rocker - link boom system increases the luffing angle, to meet the various needs of different stations working conditions, low level of play hole; carriage arranged laterally to make work better field of vision.

6. Cylinder - plate chain propulsion system consisting of a two-speed motor and two-speed dual circulator to meet different application requirements.

7. The drilling rig is low center of gravity and balanced distribution, with heavy "Four Wheels" and there are 19 ° and automatic leveling device can be independently controlled double locking system, and the frame has a ± 10 ° automatic leveling device, walking safe and stable.

8.The drilling rig equiped a high efficiency two-stage dry dust collection system, greatly improve the working environment, meets the energy saving, environmental protection concept.
