With a weight of 300 kg, it balances operational flexibility and structural robustness. Its drill diameter ranges from 70-170 mm, covering most large-scale blasting hole requirements for medium mining projects. Notably, its 55 kW reliable hydraulic power delivers consistent impact force. It excels in 2200m deep underground tunnels and medium-large open-pit mines, handling diverse rock and environmental conditions with ease.
This Hydraulic Drifter undergoes strict factory quality control and reliability testing. It ensures 100% compatibility with Atlas Copco/Epiroc standard and mid-range jumbo rigs. Moreover, it eliminates critical flaws of non-original parts: unstable operation, poor environmental adaptability, and frequent malfunctions. Even in harsh working conditions (high pressure, continuous vibration, heavy dust/wetness), it maintains consistent peak performance.
Its precision-machined structure uses high-strength alloy + wear-resistant composite materials. This robust design ensures long service life and low maintenance—core advantages of its “RR11” reliable positioning. In addition, the quadruple-sealed system + corrosion-resistant coating provides superior protection against moisture and abrasive particles. It reduces maintenance frequency by 35% compared to ordinary drifters.
As a reliable universal Hydraulic Rock Drill, it features intelligent power management. It maximizes drilling productivity while reducing fuel consumption by 18%. Furthermore, its stable hydraulic system ensures smooth operation even under fluctuating loads. This makes it ideal for long-term, large-scale drilling projects in medium-large mining enterprises.
Short delivery time ensures timely equipment replacement or project startup. Competitive pricing offers cost-effective solutions for medium-large mining and construction companies. Importantly, original factory quality assurance guarantees long-term operational stability. It minimizes downtime and project delays, supporting continuous production.
Whether for 2200m deep underground tunnel excavation or coal mine drilling, it delivers reliable, high-output results. For medium-large open-pit quarry blasting, it maintains efficiency in changing weather (high temperature, heavy rain, mild freezing). Specifically, it adapts to hard rock mines, medium rock tunnels, wet quarries, and open-pit sites—meeting diverse drilling needs of medium-scale projects.
Non-original drifters often have inconsistent performance, short service lives, or high maintenance costs. They lead to extra expenses and productivity losses. In contrast, the COP RR11 Drifter retains structural integrity and reliable output. Its universal adaptation, robust design, and low maintenance empower your jumbo rigs to operate efficiently, driving profitability in medium-large mining projects.
