Xianghe, Hebei, China — August 12, 2026 — Global mining and tunnel construction projects are increasingly confronting complex geological conditions, especially ultra-hard granite, basalt and dense rock strata that place higher demands on drilling power, continuous operation stability and site adaptability. To meet diversified on-site construction needs from global contractors and mining enterprises, Hebei Shenli Pneumatic Machinery officially spotlighted its flagship S83 ultra-heavy air leg rock drill, alongside a complete lineup of pneumatic drilling equipment covering YT24, YT27, YT28, YT29A, S82 and S250 models. The full-gradient product matrix achieves full coverage from light-duty trimming, conventional mining, efficient rapid drilling, high-torque hard rock excavation to environmental-friendly wet drilling, forming a one-stop pneumatic rock drilling solution for global mining, quarrying, tunnel engineering and infrastructure reinforcement projects.
As the top-tier flagship model of Shenli’s entire air leg rock drill series, the S83 pneumatic jackleg drill is professionally developed for high-intensity continuous drilling in ultra-hard rock formations. Different from conventional medium and heavy-duty rock drills, the S83 focuses on overcoming construction pain points such as slow penetration rate, insufficient torque and easy component aging during long-term operation in f8–f18 super-hard rock. It has become the preferred core equipment for large-scale deep mine development, high-standard mountain tunnel excavation and large open-pit quarry blasting projects worldwide

As the core upgrade model of the entire product line, the S83 air leg rock drill is the only equipment in the series specially optimized for 24-hour uninterrupted heavy-duty operation on f≥16 super-hard rock formations. It achieves comprehensive upgrades in output power, energy-saving performance, dust suppression effect and overall component durability compared with S82, YT29A and S250, effectively solving the problem of insufficient continuous operation capacity of traditional rock drills in high-hardness and high-intensity working scenarios.
Diversified Application Scenarios Empower Global Mining & Infrastructure Projects
With its super-hard rock adaptability and multi-angle flexible drilling capability, the S83 flagship air leg rock drill covers multiple core application fields, delivering stable and efficient construction solutions for complex working conditions worldwide.
Underground Metal & Non-Metal Mining
The S83 is widely used for deep roadway blast hole drilling, roof and side wall anchor support construction, and secondary ore fragmentation in gold mines, copper mines, iron mines and tungsten mines. For mining areas dominated by granite and basalt strata, the S83 can completely replace traditional YT28 and S82 models, significantly improving daily tunneling efficiency and overall project output.
Open-Pit Quarrying Industry
Ideal for deep bench blast hole drilling and large stone separation operations in large-scale granite, limestone and basalt quarries. Matched with Shenli’s supporting button drill bits and tapered drill rods, it realizes one-stop procurement of drilling host and consumables, simplifying the overall construction equipment supporting system for quarry owners.
Large-Scale Tunnel Engineering
It adapts to hard rock excavation of mountain highway tunnels, railway diversion tunnels, long-distance water conservancy tunnels and urban deep metro tunnels. For urban construction sites with strict environmental protection requirements, the S83 can be used in combination with the S250 wet dust-control rock drill to realize efficient and environmentally friendly construction of mixed rock layers.
Infrastructure Slope Stabilization
The equipment supports multi-angle inclined drilling, efficiently solving the difficult anchor hole construction problems in highway mountain slope reinforcement, water conservancy dam wall support and mine waste slope renovation, making up for the insufficient operating performance of lightweight models such as YT24 in high-inclination working conditions.
Emergency Rock Breaking And Demolition Projects
It can cooperate with TPB series pneumatic breakers and W series mobile diesel air compressors to form a complete construction equipment set, suitable for mountain landslide obstacle clearance, large concrete foundation hard rock excavation and mine collapse rescue drilling, providing reliable equipment support for emergency engineering operations.
Vertical Factory Manufacturing Strength Ensures Consistent High Quality of Full Series Rock Drills
