RD520 Rock Drill is a high-performance smart universal heavy-duty New Original Hydraulic Rock Drill. It’s engineered for mid-range jumbo drill rigs, leading intelligent, efficient, and cost-effective drilling operations in medium-scale mining, deep tunneling, and open-pit quarries.

With a weight of 260 kg, it balances smart operational flexibility and robust structural design. Its drill diameter ranges from 55-140 mm, covering medium-scale blasting hole requirements for medium mining projects. Notably, its 50 kW high-efficiency hydraulic power delivers consistent and powerful impact force. It excels in 2100m deep underground tunnels and medium open-pit mines, handling medium to hard rock conditions and harsh working environments with ease.

This Hydraulic Drifter undergoes strict factory quality control and heavy-duty performance testing. It ensures 100% compatibility with Sandvik/Tamrock standard and mid-range jumbo rigs. Moreover, it eliminates critical flaws of non-original parts: unstable operation, poor environmental adaptability, and frequent malfunctions. Even in harsh conditions (high pressure, heavy dust, wetness, continuous vibration), it maintains consistent peak performance.

Its precision-machined structure uses high-strength alloy + wear-resistant/corrosion-resistant composite materials. This universal design ensures wide adaptation to different working conditions while enhancing durability—core advantages of the “RD520” series. In addition, the four-layer sealed system + anti-abrasive coating provides superior protection against moisture, dust, and abrasive particles. It extends service life by 28% compared to ordinary hydraulic drifters.

As a smart Hydraulic Rock Drill, it features advanced adaptive control technology. It automatically adjusts drilling parameters (impact force, speed, pressure) based on real-time rock hardness and depth data. This maximizes drilling productivity while reducing fuel consumption by 16%. Furthermore, its optimized hydraulic system ensures smooth operation even under fluctuating loads, making it ideal for long-term medium-scale drilling projects.

Short delivery time ensures timely equipment replacement or project startup. Competitive pricing offers cost-effective solutions for mining and construction companies, especially small to medium-scale enterprises. Importantly, original factory quality assurance guarantees long-term operational stability. It minimizes downtime and project delays, supporting continuous production in high-demand mining environments.

Whether for 2100m deep underground tunnel excavation, coal mine drilling in narrow shafts, or medium open-pit quarry blasting, it delivers reliable, high-output results. For open-pit mining, it maintains efficiency in extreme weather (high temperature, heavy rain, mild freezing). Specifically, it adapts to medium rock mines, hard rock tunnels, wet quarries, and dusty open-pit sites—meeting diverse drilling needs of medium-scale projects.

Non-original hydraulic drifters often lack heavy-duty capacity, intelligent control functions, or have short service lives. They lead to extra maintenance costs, low productivity, and financial losses. In contrast, the RD520 Rock Drill retains structural integrity, smart performance, and durable quality at a competitive price. Its advantages (smart control, universal adaptation, cost-effectiveness) empower your jumbo rigs to operate at peak efficiency, driving profitability in medium-scale mining projects.
