KT8 Integrated Surface DTH Drilling Rig

KT8 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. It both inherits advantages of KT7 drilling rig and injects new design philosophy.

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

2. Using Cummins 6CTA8.3-260 diesel engine replaced Yuchai YC6A260Z-20, big displacement 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 13/17 single-stage high-pressure compression screw system by Dr. Tang Yan, compared with mieda wind 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. 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.
