HL820ST Rock Drill is a high-quality mid-range smart heavy-duty enhanced New Original Hydraulic Rock Drill. It’s engineered for mid-range high-performance jumbo drill rigs, leading intelligent, precision-driven, and stable high-intensity drilling operations in medium-large mining, ultra-deep tunneling, and open-pit quarries.
With a weight of 390 kg, it balances flexible operational performance, reinforced structural design, and enhanced high-power output. Its drill diameter ranges from 80-200 mm, fully covering large-scale blasting hole requirements for medium-large mining projects. Notably, its 90 kW mid-range enhanced hydraulic system delivers stable, powerful, and energy-saving impact force with precision control. It excels in 2900m deep underground tunnels and medium-large open-pit mines, handling hard rock and extreme harsh working environments with extraordinary stability and vibration resistance.
This Hydraulic Drifter undergoes strict factory quality control and enhanced heavy-duty performance testing. It ensures 100% compatibility with Sandvik/Tamrock standard high-performance jumbo rigs. Moreover, it eliminates critical flaws of non-original parts: insufficient power reserve, unstable precision control, poor high-vibration adaptability, and frequent malfunctions. Even in harsh conditions (high pressure, continuous high vibration, heavy dust, wetness), it maintains consistent peak performance.
Its precision-machined structure uses ultra-high-strength alloy + premium wear-resistant/corrosion-resistant/shock-absorbing composite materials. This enhanced design integrates advanced multi-sensor technology while boosting load-bearing capacity by 43%—core advantages of the “HL820ST” enhanced series. In addition, the seven-layer sealed system + anti-abrasive/anti-corrosion/anti-vibration coating provides reliable protection against moisture, dust, corrosion, vibration, and abrasive particles. It extends service life by 48% compared to ordinary hydraulic drifters.
As a mid-range enhanced Hydraulic Rock Drill, it features practical AI-assisted adaptive precision control. It automatically adjusts drilling parameters (impact force, speed, pressure, vibration frequency) based on real-time rock hardness, depth, and environmental data. This maximizes drilling productivity and precision while reducing fuel consumption by 27%. Furthermore, its optimized enhanced hydraulic system ensures smooth operation even under fluctuating heavy loads and high vibration, making it ideal for long-term medium-large scale high-intensity drilling projects.
Short delivery time ensures timely equipment replacement or project startup. Competitive pricing offers high-cost-performance solutions for medium-large mining and construction companies. Importantly, original factory quality assurance guarantees long-term operational stability, enhanced durability, and low maintenance costs. It minimizes downtime and project delays, supporting continuous production in high-demand extreme mining environments.
Whether for 2900m ultra-deep underground tunnel excavation, coal mine drilling in narrow high-pressure shafts, or medium-large open-pit blasting, it delivers reliable, high-output, and precise results. For open-pit mining, it maintains efficiency in extreme weather (freezing cold, scorching heat, heavy rain, moderate sandstorms, high wind). Specifically, it adapts to hard rock mines, ultra-thick ore layers, high-pressure narrow tunnels, and extreme dust/wet/high-vibration quarries—meeting diverse high-intensity drilling needs of medium-large scale projects.
Non-original hydraulic drifters often lack enhanced heavy-duty capacity, reliable precision control, or have short service lives. They lead to extra maintenance costs, low productivity, and significant financial losses. In contrast, the HL820ST Rock Drill retains structural integrity, mid-range smart precision performance, and enhanced high-power output. Its advantages (mid-range smart precision control, enhanced durability & vibration resistance, high-power efficiency) empower your jumbo rigs to operate at peak efficiency, driving profitability in medium-large mining projects.
