With its reinforced high-pressure and heavy-duty integrated structural design, it balances powerful performance, operational flexibility, and precision drilling—ideal for both underground deep tunnels (high pressure) and open-pit large-scale projects. Its hole range of 38-64 mm perfectly covers medium-diameter precision blasting hole requirements, while the 18 kW impact power delivers robust, energy-saving drilling force. Notably, the 60 Hz impact frequency (3600 bpm) ensures steady, deep-penetrating efficiency, making it a top choice for mid-large projects requiring both high pressure and consistent accuracy.
This Hydraulic Rock Drill undergoes strict factory quality control and high-pressure heavy-duty enhanced precision testing. It ensures 100% compatibility with standard and mid-large capacity jumbo rigs, eliminating critical flaws of non-original parts: unstable load-bearing, imprecise drilling, poor high-pressure adaptability, and frequent malfunctions. Even in harsh conditions (high pressure, moderate-high 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 reinforced high-pressure design enhances load-bearing capacity, pressure stability, and durability while preserving drilling accuracy—core advantages of the “COP 1838HD+” enhanced 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 50% compared to ordinary mid-large hydraulic drifters.
As a mid-large high-pressure heavy-duty enhanced 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. This maximizes drilling productivity while reducing fuel consumption by 28%. Furthermore, its compatibility with multiple shank adapters (R32/R38/T38) enhances universal adaptation, supporting seamless integration with diverse jumbo rig configurations.
Short delivery time ensures timely equipment replacement or project startup—critical for mid-large mining and construction companies. Competitive pricing offers high-cost-performance solutions, especially for enterprises focusing on high-pressure large-scale 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 mid-large scale mining environments.
Whether for mid-large underground mine drilling, deep tunnel excavation, open-pit large-scale blasting, or high-pressure 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 handles medium-diameter blasting holes with consistent efficiency. Specifically, it adapts to hard rock mines, medium-hard rock tunnels, high-pressure underground sites, and dusty/wet open-pit quarries—meeting diverse mid-large high-pressure heavy-duty precision drilling needs.
Non-original hydraulic drifters often lack high-pressure enhanced capacity, precision control, or durable structures. They lead to extra maintenance costs (3x higher than original parts), low productivity, and significant financial losses for mid-large enterprises. In contrast, the COP 1838HD+ Hydraulic drifter retains structural integrity, high-pressure heavy-duty enhanced precision, and reliable efficiency at a competitive price. Its advantages (high-pressure enhanced performance, precision drilling, multi-adapter compatibility, cost-effectiveness) empower your jumbo rigs to operate at peak efficiency, driving profitability in mid-large scale mining projects.
