roduct characteristics:

Model KT8 open-pit DTH drilling rig is an advanced drilling equipment with high efficiency and energy saving, which is carefully developed for small and medium-sized open-pit mining, quarry and infrastructure construction projects. It inherits the advantages of the KT7 drilling truck and injects new design concepts.

1. the overall layout is more reasonable and easy to maintain.

2. Using Cummins 6CTA8.3-260 diesel engine to replace Yuchai YC6A260Z-20, the displacement and torque reserve are large, and it can provide more power support in harsh environment.

3. the hydraulic system adopts a relatively independent multi pump system, which eliminates the shunt valve and is more stable.

4. Equipped with Dr. Tang Yan's 13/17 single-stage high wind pressure screw compression system, it has overwhelming advantages over other manufacturers'wind pressure monolithic drilling rigs.

5. The drilling arm system with rocker arm-connecting rod enlarges the angle of amplitude variation, meets the needs of different workstations under various working conditions, and can drill low-level holes; the lateral arrangement of sliding frame makes the working field better.

6. The two-speed propulsion system composed of cylinder-plate chain and the two-motor two-speed gyrator can meet the requirements of different working conditions.

7. The rig has a low center of gravity and balanced distribution. It is equipped with a heavy-duty "four-wheeled belt" and a high-torque walking motor with mechanical/hydraulic double brakes. The frame has an automatic leveling device of

8. The drilling rig is equipped with two-stage dry dust collection system, which greatly improves the working environment and accords with the concept of energy saving and environmental protection.
