This Hydraulic Drifter undergoes strict factory quality inspections to ensure 100% compatibility with Atlas Copco/Epiroc jumbo drill rigs. It eliminates common issues like low drilling efficiency, unstable performance, and frequent malfunctions that plague non-original alternatives, especially in harsh environments with dust, moisture, and continuous vibration.
Its precision-engineered structure and high-strength alloy components deliver powerful impact force and consistent drilling performance. The 32 kW rated hydraulic power converts into high-frequency mechanical impact, enabling fast and accurate blasting hole drilling (45-130 mm) — critical for improving project progress in large-scale mining and tunnel excavation. At 185 kg, it balances portability and stability, fitting seamlessly with standard and mid-sized jumbo rig configurations for long-duration drilling tasks.
The COP 628 Drifter features a sealed design and corrosion-resistant materials. It resists hydraulic oil erosion, abrasive particles, and extreme temperature fluctuations, maintaining reliable operation in deep underground tunnels with poor ventilation and open-pit sites with changing weather conditions.
As a dedicated Hydraulic Rock Drill for jumbo rigs, it optimizes energy efficiency while maximizing drilling output. It reduces fuel consumption and operational costs, making it an ideal choice for mining companies and construction teams seeking cost-effective and high-performance equipment.
Key benefits include short delivery time and competitive pricing. This makes it a practical solution for timely equipment replacement, maintenance, or fleet expansion, minimizing downtime and project delays.
Non-original Hydraulic Drifters often fail to match the original’s performance or durability, leading to costly repairs and reduced productivity. But the COP 628 Drifter maintains structural integrity and performance stability long-term, supported by original factory quality assurance.
Whether for underground tunnel excavation, coal mine drilling, or open-pit quarry blasting, this Hydraulic Rock Drill delivers consistent, reliable results. It empowers your jumbo drill rigs to operate at peak efficiency, driving productivity and profitability in large-scale drilling operations.
