With its reinforced extreme-resistant + large-bore + multi-adapter integrated structural design, it balances powerful performance, operational flexibility, and precision drilling—ideal for underground deep tunnels (high pressure/extreme vibration) and open-pit extreme sites (low temperature/high corrosion). Its hole range of 76-102 mm perfectly covers large-diameter blasting hole requirements, while the 19 kW impact power delivers consistent, energy-saving drilling force. Notably, the 50 Hz impact frequency (3000 bpm) ensures steady, deep-penetrating efficiency for large-bore holes, the specialized extreme-resistant coating enhances durability in harsh environments, and the multi-adapter compatibility supports diverse rig configurations—making it a top choice for projects in extreme working conditions with variable adapter needs.
This Hydraulic Rock Drill undergoes strict factory quality control and extreme-resistant large-bore multi-adapter 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 extreme-environment adaptability, weak adapter compatibility, and frequent malfunctions. Even in harsh conditions (extreme pressure, extreme vibration, heavy dust, wetness, high corrosion, -35℃ to 65℃ temperature range), it maintains consistent peak performance—backed by original factory manufacturing standards.
Its precision-machined structure uses high-strength corrosion-resistant alloy + premium wear-resistant/shock-absorbing composite materials. The integrated extreme-resistant, large-bore, and multi-adapter design enhances drilling stability, efficiency, environmental resilience, and adapter matching flexibility while preserving accuracy—core advantages of the “COP 1840EX+” series. In addition, the multi-layer sealed system + anti-abrasive/anti-corrosion/anti-temperature-shock coating provides all-around protection against moisture, dust, corrosion, and extreme temperature fluctuations. It extends service life by 58% compared to ordinary large-bore hydraulic drifters.
As a large-bore extreme-resistant multi-adapter high-efficiency Hydraulic drifter, it features practical adaptive control technology. It automatically adjusts drilling parameters based on real-time rock hardness and environmental data—complementing its 230 bar hydraulic pressure to ensure smooth, powerful operation even in extreme conditions. This maximizes drilling productivity (32% faster than conventional large-bore models) while reducing fuel consumption by 29%. Furthermore, its compatibility with three types of enhanced shank adapters (T38E/T45E/T51E) enhances universal adaptation, supporting seamless integration with diverse large-capacity jumbo rig configurations and different rock formation drilling needs.
Short delivery time ensures timely equipment replacement or project startup—critical for large-scale mining and construction companies operating in extreme areas. Competitive pricing offers high-cost-performance solutions, especially for enterprises needing extreme-condition large-bore drilling reliability and flexible adapter matching. Importantly, original factory quality assurance guarantees long-term operational stability, reinforced extreme resistance, and low maintenance costs. It minimizes downtime (less than 0.5% annual failure rate) and project delays, supporting continuous production in extreme mining environments.
Whether for large-scale underground mine drilling (high temperature/high corrosion), deep tunnel excavation (high pressure/extreme vibration), open-pit large-bore extreme blasting (low temperature/heavy dust), or heavy-duty precision drilling tasks with different adapter needs, it delivers reliable, high-precision results. For underground operations, its rugged design withstands extreme pressure and vibration; for open-pit projects, it resists low temperature and high corrosion while handling large-diameter blasting holes (76-102mm) with consistent efficiency and flexible adapter matching. Specifically, it adapts to hard rock mines, deep high-pressure tunnels, high-vibration open-pit quarries, and high-corrosion mining areas—meeting diverse extreme large-bore heavy-duty precision drilling needs with multi-adapter compatibility.
Non-original hydraulic drifters often lack extreme-environment resistance, large-bore adaptability, multi-adapter compatibility, 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 1840EX+ Hydraulic drifter retains structural integrity, extreme-resistant large-bore precision, and reliable efficiency at a competitive price. Its advantages (extreme-environment adaptation, large-bore drilling, multi-adapter universal compatibility, high-efficiency performance, heavy-duty durability, cost-effectiveness) empower your jumbo rigs to operate at peak efficiency, driving profitability in extreme large-scale mining and blasting projects.
