With its balanced structural design, it combines operational flexibility and heavy-duty performance—ideal for both underground narrow spaces and open-pit large-scale operations. Its hole range of 33-64 mm covers a wider spectrum of small to medium-diameter blasting hole requirements, while the 11 kW impact power delivers consistent, energy-saving drilling force. Notably, the 75 Hz impact frequency (4500 bpm) ensures steady drilling efficiency, making it a go-to choice for mid-small to medium projects requiring both precision and scale.

This Hydraulic Rock Drill undergoes strict factory quality control and precision heavy-duty performance testing. It ensures 100% compatibility with Atlas Copco/Epiroc standard jumbo rigs, eliminating critical flaws of non-original parts: unstable precision, weak load-bearing capacity, poor environmental adaptability, and frequent malfunctions. Even in harsh conditions (general pressure, moderate vibration, heavy dust, wetness), it maintains consistent peak performance—backed by original factory manufacturing standards.

Its precision-machined structure uses high-strength alloy + wear-resistant/corrosion-resistant composite materials. The optimized design enhances durability while ensuring drilling accuracy—core advantages of the “COP 1140” series. In addition, the multi-layer sealed system + anti-abrasive/anti-corrosion coating provides reliable protection against moisture, dust, and abrasive particles. It extends service life by 38% compared to ordinary mid-small hydraulic drifters.

As a mid-small to medium precision Hydraulic drifter, it features practical adaptive control technology. It automatically adjusts drilling parameters based on real-time rock hardness and depth data—complementing its 180 bar hydraulic pressure to ensure smooth, precise operation. This maximizes drilling productivity while reducing fuel consumption by 22%. Furthermore, its compatibility with multiple shank adapters (R32/SR32/TC35) enhances universal adaptation, allowing seamless integration with different jumbo rig configurations.

Short delivery time ensures timely equipment replacement or project startup—critical for mid-small to medium mining and construction companies. Competitive pricing offers high-cost-performance solutions, especially for enterprises balancing precision and operational scale. Importantly, original factory quality assurance guarantees long-term operational stability and low maintenance costs. It minimizes downtime and project delays, supporting continuous production in medium-scale mining environments.

Whether for medium-scale underground mine drilling, tunnel excavation, or open-pit quarry blasting, it delivers reliable, high-precision results. For underground operations, its flexible design navigates limited spaces effectively, while its dust and moisture resistance ensures performance in harsh underground environments. For open-pit projects, it handles medium-scale blasting hole drilling with consistent efficiency. Specifically, it adapts to medium-hard rock mines, soft-hard rock tunnels, wet quarries, and dusty open-pit sites—meeting diverse mid-small to medium precision drilling needs.

Non-original hydraulic drifters often lack versatile adaptation, precision control, or durable structures. They lead to extra maintenance costs, low productivity, and financial losses for mid-small to medium enterprises. In contrast, the COP 1140 Hydraulic drifter retains structural integrity, versatile precision performance, and reliable efficiency at a competitive price. Its advantages (versatile adaptation, precision drilling, cost-effectiveness) empower your jumbo rigs to operate at peak efficiency, driving profitability in mid-small to medium mining projects.
