Training new drilling personnel can be challenging. The YT28 is often selected for training environments due to its controllable impact force and balanced operation. Reduced vibration and predictable drilling response help new operators develop proper technique quickly, improving safety and overall project efficiency. As a professional rock drilling machinery manufacturer, Shenli Pneumatic Machinery Co., Ltd. designs the YT28 air leg rock drill for versatility—ideal for wet drilling in medium to hard rock, with a drilling diameter of 34-42mm and maximum depth of 5m. Operation is intuitive: connect the air and water pipes, adjust the air pressure to 0.5-0.63MPa, and use the centralized control handle to start drilling; its air-water linkage system ensures dust suppression, while the quick-retracting air leg adapts to different working angles. Mines switching from ordinary rock drills to the YT28 have noticed a stark difference—traditional models require more physical effort, produce higher noise (exceeding 130dB(A)), and achieve only 200-250mm/min drilling speed. The YT28 cuts noise to ≤127dB(A) and boosts speed to over 350mm/min, slashing fatigue and downtime.

 

Choosing Shenli Pneumatic Machinery means partnering with a brand rooted in over 15 years of industry expertise. We prioritize durability in every component—our YT28 uses high-wear resistant materials for core parts, extending service life by 30% compared to generic alternatives. Our in-house R&D team continuously optimizes designs, such as the integrated silencer cover that improves workplace comfort, and we offer full after-sales support, including on-site maintenance training and quick access to spare parts. Unlike suppliers who compromise on quality, we adhere to strict production standards, ensuring each YT28 passes 12 quality checks before delivery.

Efficiency gains with the YT28 are quantifiable: mines report a 40% increase in daily drilling footage. A coal mine in Shanxi, for example, increased monthly tunnel progress from 80m to 112m after adopting our YT28s. The drill’s balanced design reduces operator training time by 50%—new staff master basic operations in 3 days instead of the usual 6. Fuel costs also drop by 15% thanks to its optimized air consumption (≤75L/s), a critical saving for large-scale mining operations.

The advantages go beyond speed and cost. The YT28’s lightweight (28kg) design reduces handling effort, lowering work-related injuries by 60%. Its compatibility with FT160BD/BC air legs and trolley mounts adds flexibility for horizontal, inclined, or overhead drilling. The simple structure means maintenance is straightforward—most issues can be resolved on-site with basic tools, cutting maintenance time by 40%. For mines and construction teams, these benefits translate to on-time projects, lower operational costs, and safer workplaces. “The YT28 changed how we train and operate,” said a mining supervisor. “It’s reliable, easy to use, and the efficiency gains speak for themselves.”
