Advantage
The KT8 high pressure integrated drilling rig, for small and mid-sized open-pit mining, quarrying and infrastructure construction projects, is highly efficient using energy-saving advanced drilling techniques. It incorporates the advantages of the KT7 drilling rig with a new design concept and the following features:
1. An overall layout that is easy to maintain and maneuver.
2. 6CTA8.3-260 Cummins diesel engine replaces the Yuchai YC6A260Z-20 engine for a larger displacement and torque and more power in harsh working environments.
3. A hydraulic independent multi-pump system that cancels the diverter valve and provides stability.
4. Equipped with a 13/17 single-stage high-pressure screw air compression system.
5. A rocker-link drill boom system increases the lifting boom angle of the open-air rig to meet various working conditions, especially for deep holes. The carriage laterally arranged gives the operator good vision.
6. Cylinder-plate chain consisting of a two-speed propulsion system and dual two-speed rotary motor to meet the requirements of different applications.
7. A low center of gravity and balanced distribution, with heavy four wheels, a mechanical/hydraulic dual brake torque travel motor and frame with ± 10 ° automatic leveling device for safe and stable movement.
8. The integrated open-air crawler drilling rig is equipped with an efficient two-stage dry dust collection system, keeping the working environment cleaner and saving energy.
