COP 1840 Hydraulic drifter is a high-quality large-bore high-power heavy-duty New Original Hydraulic Rock Drill. It’s engineered for jumbo drill rigs, leading robust, efficient, and reliable large-scale drilling operations in large mining sites, deep tunneling, and open-pit quarries—focused on large-bore heavy-duty needs with superior high-power performance.
With its optimized large-bore and high-power integrated structural design, it balances extreme power output, operational stability, and precision drilling—ideal for both underground deep tunnels (high pressure) and open-pit large-scale blasting projects. Its hole range of 76-102 mm perfectly covers large-diameter blasting hole requirements, while the 20 kW impact power delivers unmatched, energy-saving drilling force. Notably, the 50 Hz impact frequency (3000 bpm) ensures steady, deep-penetrating efficiency for large-bore holes, making it a top choice for projects requiring high productivity in large-scale mining and blasting.
This Hydraulic Rock Drill undergoes strict factory quality control and large-bore high-power heavy-duty precision testing. It ensures 100% compatibility with standard and large-capacity jumbo rigs, eliminating critical flaws of non-original parts: unstable load-bearing, imprecise large-bore drilling, poor high-pressure adaptability, and frequent malfunctions. Even in harsh conditions (high pressure, moderate vibration, heavy dust, wetness), it maintains consistent peak performance—backed by original factory manufacturing standards.
Its precision-machined structure uses high-strength rugged alloy + premium wear-resistant/corrosion-resistant composite materials. The optimized large-bore and high-power design enhances load-bearing capacity, drilling stability, and durability for large-diameter holes while preserving accuracy—core advantages of the “COP 1840” series. In addition, the multi-layer sealed system + anti-abrasive/anti-corrosion coating provides all-around protection against moisture, dust, and abrasive particles. It extends service life by 53% compared to ordinary large-bore hydraulic drifters.
As a large-bore high-power Hydraulic drifter, it features practical adaptive control technology. It automatically adjusts drilling parameters based on real-time rock hardness and depth data—complementing its 230 bar hydraulic pressure to ensure smooth, powerful operation for large-bore drilling. This maximizes drilling productivity (27% faster than conventional large-bore models) while reducing fuel consumption by 28%. Furthermore, its compatibility with enhanced shank adapters (T38E/T45E/T51E) enhances universal adaptation, supporting seamless integration with mainstream large-capacity jumbo rig configurations.
Short delivery time ensures timely equipment replacement or project startup—critical for large-scale mining and construction companies. Competitive pricing offers high-cost-performance solutions, especially for enterprises focusing on large-bore heavy-duty drilling. Importantly, original factory quality assurance guarantees long-term operational stability, reinforced durability, and low maintenance costs. It minimizes downtime and project delays, supporting continuous production in large-scale mining environments.
Whether for large-scale underground mine drilling, deep tunnel excavation, open-pit large-bore blasting, or heavy-duty precision drilling tasks, it delivers reliable, high-precision results. For underground operations, its rugged design withstands high pressure and vibration; for open-pit projects, it efficiently handles large-diameter blasting holes (76-102mm) with consistent performance. Specifically, it adapts to hard rock mines, deep tunnels, high-pressure underground sites, and dusty/wet open-pit quarries—meeting diverse large-bore heavy-duty precision drilling needs.
Non-original hydraulic drifters often lack large-bore adaptability, high-power performance, or durable structures. They lead to extra maintenance costs (3x higher than original parts), low productivity, and significant financial losses for large-scale enterprises. In contrast, the COP 1840 Hydraulic drifter retains structural integrity, large-bore high-power precision, and reliable efficiency at a competitive price. Its advantages (large-bore adaptation, high-power drilling, heavy-duty durability, enhanced adapter compatibility, cost-effectiveness) empower your jumbo rigs to operate at peak efficiency, driving profitability in large-scale mining and blasting projects.
