Manufactured by Shenli Machinery Pneumatic Company, a professional manufacturer dedicated to rock drilling machinery with years of industry experience, the YT27 is a high-efficiency pneumatic air-leg rock drill designed specifically for seasonal quarry operations, mining, road construction and tunnel drilling tasks. We focus on independent R&D, production and quality control, ensuring every piece of equipment meets the strictest industry standards and adapts to the harsh working conditions of quarries.
The YT27 is easy to operate and maintain, even for new operators. Before use, unpack the machine, clean the internal anti-rust grease with a small amount of lubricating oil, and then fill the FY250 lubricator with air tool oil to ensure all parts are fully lubricated. Check that the air and water inlets are unobstructed, the drill steel and bit are intact, and all fittings are tight and leak-proof. During operation, open the main air valve and flushing water cock, adjust the feed lever for appropriate force, align the drill with the target point, and push the throttle lever to start percussion, rotation and flushing. After use, close the throttle, disassemble the water pipe to blow off residual moisture, and lubricate key parts for storage—a simple process that saves valuable working time.
Compared with ordinary air-leg rock drills used in mines previously, the YT27 brings revolutionary improvements. Ordinary drills often suffer from low impact energy, slow drilling speed and frequent breakdowns, requiring frequent maintenance that wastes 20-30% of working hours. They also consume more air and are prone to overheating during long-term operation, failing to meet the tight schedules of seasonal quarries. In contrast, the YT27 boosts drilling efficiency by 45%—it can drill 34-45mm diameter holes up to 5 meters deep at a speed of over 480mm per minute, cutting down drilling time for each blast hole by nearly half. It also reduces air consumption by 18% and has a failure rate 70% lower than ordinary models, minimizing interruptions and maximizing production during limited operating windows.
Choosing Shenli Machinery Pneumatic Company means choosing reliability, efficiency and professional support. Unlike other manufacturers that rely on external parts procurement, we control the entire production chain from core component processing to final assembly, ensuring consistent quality and stable performance. Our YT27 is equipped with a high-precision cylinder and piston, delivering impact energy of no less than 75.5J and impact frequency up to 40Hz, with strong hole-cleaning capacity and easy operation. Beyond product quality, we provide one-year warranty, timely after-sales service and technical guidance, helping you solve any operation or maintenance issues quickly. For seasonal quarries striving to maximize output in short time frames, the YT27 from Shenli is the most cost-effective choice, bringing higher efficiency, lower costs and more reliable performance to every drilling task.
