With a weight of 72 Kg (158 Ib), it balances upgraded operational flexibility and reinforced structural robustness. Its drill diameter ranges from 80-190 mm, covering large-scale blasting hole requirements for large mining projects. Notably, its 75 kW enhanced hydraulic power delivers consistent, powerful, and energy-efficient impact force. It excels in 2600m deep underground tunnels and large open-pit mines, handling complex rock conditions and harsh environments with ease.
This Hydraulic Drifter undergoes strict factory quality control and enhanced heavy-duty performance testing. It ensures 100% compatibility with Montabert standard and high-performance jumbo rigs. Moreover, it eliminates critical flaws of non-original parts: unstable heavy-duty operation, poor environmental adaptability, and frequent malfunctions. Even in harsh working conditions (high pressure, continuous vibration, heavy dust/wetness), it maintains consistent peak performance.
Its precision-machined structure uses high-strength alloy + upgraded wear-resistant/corrosion-resistant composite materials. This enhanced design ensures faster drilling speed and longer service life—core advantages of the “HC25” upgrade. In addition, the six-layer sealed system + anti-abrasive coating provides superior protection against moisture, dust, and abrasive particles. It extends service life by 40% compared to ordinary drifters.
As an enhanced universal Hydraulic Rock Drill, it features advanced intelligent power management. It maximizes drilling productivity while reducing fuel consumption by 25%. Furthermore, its upgraded hydraulic system ensures smooth operation even under fluctuating heavy loads. This makes it ideal for long-term, large-scale drilling projects in large mining enterprises.
Short delivery time ensures timely equipment replacement or project startup. Competitive pricing offers cost-effective solutions for large mining and construction companies. Importantly, original factory quality assurance guarantees long-term operational stability. It minimizes downtime and project delays, supporting continuous production.
Whether for 2600m deep underground tunnel excavation or coal mine drilling, it delivers reliable, high-output results. For large open-pit quarry blasting, it maintains efficiency in extreme weather (high temperature, heavy rain, freezing cold). Specifically, it adapts to hard rock mines, medium rock tunnels, wet quarries, dusty open-pit sites, and high-pressure underground spaces—meeting diverse drilling needs of large-scale projects.
Non-original drifters often lack heavy-duty capacity, have inconsistent performance, or require frequent maintenance. They lead to extra costs and productivity losses. In contrast, the HC25 Drifter retains structural integrity and enhanced high-efficiency output. Its enhanced universal adaptation, robust design, and low maintenance cost empower your jumbo rigs to operate efficiently, driving profitability in large-scale mining projects.
