Narrow tunnel profiles require precise drilling to avoid overbreak. The YT27 provides controlled impact energy, allowing operators to shape tunnel faces accurately.
This precision reduces excess excavation and lowers material handling costs later in the construction process.
Operating the YT27 is streamlined for on-site efficiency, requiring minimal training for operators. It pairs seamlessly with FY250 oil injectors and FT160A/FT160B legs; prior to use, ensure the air pressure is set to 0.5-0.63MPa and water pressure to 0.3MPa, then check the oil injector’s transparent reservoir to confirm adequate lubrication. The integrated air-water linkage system enables wet drilling, significantly reducing dust levels, while the centralized control handles allow for easy adjustment of drilling parameters. Post-operation, simply disconnect the water pipe and run the machine briefly to blow out residual moisture, preventing internal corrosion—a small step that extends the drill’s service life substantially.
The difference between the YT27 and conventional rock drills is transformative for quarry operations. Traditional models often struggle with frequent breakdowns in dusty or temperature-fluctuating environments, leading to 2-3 hours of daily downtime for repairs. In contrast, the YT27’s flange control valve and wear-resistant components—treated with advanced heat technology—cut failure rates by 70%, ensuring non-stop operation during 8-hour shifts. A local quarry reported that switching from old drills to the YT27 boosted drilling speed from 1.2m/min to 1.5m/min, increasing daily output by 120-150 meters. Energy efficiency is another standout: the YT27 consumes 20% less air than conventional models, translating to a 30% reduction in monthly energy costs.
Our factory’s commitment to quality underpins the YT27’s reliability. We oversee the entire production process, from sourcing high-grade steel to implementing automated assembly lines that keep defect rates below 0.1%. Each unit undergoes rigorous testing in simulated quarry conditions, including dust exposure and temperature cycles from -10°C to 45°C, to ensure consistent performance. We also provide a 12-month warranty, 24-hour technical support, and a comprehensive spare parts supply network—services that have earned us a 92% customer repurchase rate. For quarries seeking to balance efficiency, safety, and cost-effectiveness, the YT27 is more than a tool; it’s a long-term investment backed by a manufacturer that understands the demands of rock drilling.
