KT integrated open-air DTH drill rig
KT6C Integrated Open-pit Down-the-Hole (DTH) Drill Rig

introduction and Parameter:

Equipped with Kaishan two-stage compression 15/18 airend, it delivers large air displacement with high energy efficiency to meet heavy-duty rock drilling demands.Fitted with low-fuel-consumption Yuchai high-performance diesel engine and high-flow desert air filter, the machine ensures stable, reliable, eco-friendly operation.Dual-motor rotary device with high torque and rotating speed boosts drilling efficiency. Matched with high-efficiency dust collection system and double dust capture cylinder structure, it achieves safe, durable and environment-friendly performance.Reinforced drill arm base enhances structural durability. Extended drill arm expands drilling coverage per positioning and improves working efficiency.Optimized controller displays all operating data clearly. Reversing camera expands visual field and guarantees driving safety.Rainproof and sunshade canopy enables normal operation under harsh weather. Optimized internal layout facilitates daily maintenance.Capable of drilling vertical, inclined and horizontal holes, suitable for open-pit mines and rock engineering projects.
