With a weight of 190 kg (419), it balances premium operational flexibility, reinforced ultra-high-strength structural design, and extreme power output. Its drill diameter ranges from 85-220 mm, fully covering mega-scale blasting hole requirements for ultra-large mining projects. Notably, its 110 kW ultra-power hydraulic system delivers stable, extreme-impact, and energy-saving force with millimetric precision control. It excels in 3200m ultra-deep underground tunnels and mega open-pit mines, handling extra-hard rock and extreme harsh environments with unparalleled stability.

This Hydraulic Rock Drill undergoes rigorous factory quality control and extreme heavy-duty performance testing (1000+ hours of continuous operation under ultra-high pressure). It ensures 100% compatibility with Montabert premium and flagship jumbo rigs. Moreover, it eliminates critical flaws of non-original parts: insufficient power reserve, unstable precision control, weak extreme-environment adaptability, and frequent breakdowns. Even in harsh conditions (ultra-high pressure, continuous high vibration, heavy dust, wetness, corrosion, high temperature), it maintains consistent peak performance.

Its precision-machined structure uses aerospace-grade titanium alloy + premium nano-wear-resistant/corrosion-resistant/shock-absorbing composite materials. This flagship design integrates advanced multi-sensor fusion technology while boosting load-bearing capacity by 55%—core advantages of the “HC158” series. In addition, the nine-layer sealed system + anti-abrasive/anti-corrosion/anti-high-temperature coating provides superior protection against moisture, dust, corrosion, vibration, and high-temperature erosion. It extends service life by 58% compared to ordinary hydraulic drifters.

As a premium flagship Hydraulic drifter, it features state-of-the-art AI-assisted adaptive precision control. It automatically adjusts drilling parameters (impact force, speed, pressure, vibration frequency, cooling intensity) based on real-time rock hardness, depth, temperature, and environmental data. This maximizes drilling productivity and precision while reducing fuel consumption by 33%. Furthermore, its optimized ultra-power hydraulic system ensures smooth operation even under fluctuating ultra-heavy loads, making it ideal for long-term mega-scale high-intensity drilling projects.

Short delivery time ensures timely equipment replacement or project startup (average lead time 7-15 working days). Competitive pricing offers cost-effective solutions for mega mining and construction groups. Importantly, original factory quality assurance (2-year warranty) guarantees long-term operational stability, extreme durability, and minimal maintenance costs. It minimizes downtime and project delays, supporting continuous production in high-demand extreme mining environments.

Whether for 3200m ultra-deep underground tunnel excavation, coal mine drilling in narrow ultra-high-pressure shafts, or mega-scale open-pit blasting, it delivers reliable, high-output, and precise results. For open-pit mining, it maintains efficiency in extreme weather (freezing cold -30℃, scorching heat 60℃, heavy rain, sandstorms, high wind). Specifically, it adapts to extra-hard rock mines, ultra-thick ore layers, ultra-high-pressure narrow tunnels, and extreme dust/wet/corrosive/high-temperature quarries—meeting diverse mega-scale drilling needs of ultra-large projects.

Non-original hydraulic drifters often lack ultra-heavy-duty capacity, advanced precision control, or have short service lives. They lead to extra maintenance costs (3x higher than original parts), low productivity (25% lower efficiency), and massive financial losses. In contrast, the HC158 Hydraulic drifter retains structural integrity, premium smart precision performance, and extreme power output. Its advantages (cutting-edge smart control, extreme durability, ultra-high efficiency) empower your jumbo rigs to operate at peak efficiency, driving profitability in mega-scale mining projects.
