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 and frequent malfunctions that plague non-original alternatives, especially in harsh underground or open-pit environments.
Its precision-engineered structure delivers powerful impact force and stable drilling performance. The 35 kW rated hydraulic power converts into high-frequency mechanical impact, enabling fast and accurate blasting hole drilling (48-135 mm) — critical for improving project progress in tunnel excavation and open-pit mining. At 210 kg, it balances robustness and stability, fitting seamlessly with heavy-duty jumbo rig configurations for intensive drilling tasks.
The RD22U Drifter features high-strength alloy components and a reinforced sealed design. It resists dust, moisture, and continuous vibration, maintaining reliable operation in extreme conditions such as deep underground tunnels with poor ventilation and open-pit sites with drastic temperature fluctuations.
As a dedicated Hydraulic Rock Drill for jumbo rigs, it balances power and energy efficiency. It reduces fuel consumption while maximizing drilling output, making it ideal for long-duration mass drilling projects in mining and tunneling.
Key benefits include short delivery time and competitive pricing. This makes it a cost-effective solution for mining companies and construction teams needing timely equipment replacement or expansion.
Non-original Hydraulic Drifters often fail to withstand heavy loads or adapt to dual-scenario use, leading to costly downtime and project delays. But the RD22U 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 results. It empowers your jumbo drill rigs to operate at peak efficiency, driving productivity in large-scale drilling operations.
