With a weight of 290 kg, it boasts exceptional structural rigidity and operational stability. Its drill diameter ranges from 70-175 mm, covering ultra-large blasting hole requirements. Notably, its 55 kW enhanced hydraulic power delivers industry-leading impact force. It excels in ultra-deep underground tunnels (up to 1500m) and mega open-pit mines, handling the most demanding heavy-duty tasks with ease.
This Hydraulic Drifter undergoes strict factory quality control and upgrade testing. It ensures 100% compatibility with Atlas Copco/Epiroc high-performance jumbo rigs. Moreover, it eliminates critical flaws of non-original parts: insufficient power, weak durability, and frequent malfunctions. Even in extreme conditions (high pressure, continuous vibration, heavy dust), it maintains consistent peak performance.
Its precision-machined structure uses premium aerospace-grade alloy components. This design ensures faster drilling speed and 20% less wear than standard models. In addition, the intelligent triple-sealed system + corrosion-resistant coating provides superior protection. It effectively repels moisture, hydraulic oil erosion, and abrasive particles, extending service life by 40% (key “Plus” upgrade).
As a flagship Hydraulic Rock Drill for heavy-duty rigs, it features intelligent power management. It maximizes drilling productivity while reducing fuel consumption by 18%. Furthermore, the “Plus” version adds energy recovery technology, lowering long-term operational costs. This makes it ideal for long-duration, ultra-large-scale drilling projects.
Short delivery time ensures timely equipment replacement or fleet expansion. Competitive pricing offers cost-effective solutions for premium heavy-duty equipment needs. Importantly, original factory quality assurance + “Plus” upgrade warranty guarantees long-term stability. It minimizes downtime and project delays, supporting critical operations.
Whether for ultra-deep underground tunnel excavation (up to 1500m) or coal mine drilling, it delivers reliable results. For mega open-pit quarry blasting, it maintains efficiency in extreme weather (high temperature, heavy rain, freezing conditions). Specifically, it adapts to poor ventilation in deep tunnels and drastic temperature fluctuations in open pits.
Non-original drifters often fail under ultra-heavy loads or long-duration use. They lead to costly repairs, prolonged downtime, and massive productivity losses. In contrast, the COP 1638+ Drifter retains structural integrity and performance consistency. Its “Plus” upgrades (enhanced power, intelligent efficiency, longer life) empower your jumbo rigs to operate at peak efficiency, driving productivity, safety, and profitability in extreme environments.
