In railway, highway, and hydropower tunnel excavation, dust and vibration control are critical. The YT28 supports wet drilling systems that reduce dust particles and create a safer working atmosphere.

Its smooth impact frequency helps maintain drilling precision, ensuring correct blast hole angles and improving tunnel face shaping. This leads to reduced over-break and lower concrete lining costs later in construction.

Building on this foundation, the YT28 rock drill introduces a new paradigm in underground drilling efficiency and operator welfare. A key engineering focus has been the significant dampening of harmful vibration transmission to the operator. This low-vibration design directly mitigates the risk of Hand-Arm Vibration Syndrome (HAVS), a common occupational injury, thereby enhancing long-term worker health and reducing equipment fatigue. Furthermore, the integration of wet drilling is not merely an option but a core feature. By injecting water directly through the drill steel, the system effectively suppresses silica dust at its source. This is a vital safeguard against silicosis, ensuring better air quality in the confined space of a tunnel and providing clearer visibility for the drilling crew.

The benefits extend beyond the immediate work environment to the project's overall economics and timeline. The drill's exceptional stability during operation allows operators to achieve and maintain perfect blast hole alignment with consistent accuracy. This precision directly translates to a cleaner, more predictable tunnel profile after each blast. The result is a substantial minimization of over-break—the excavation of rock beyond the intended design line. With less over-break, projects require far less shotcrete and concrete for lining, leading to significant savings on material costs and labor. Contractors report not only a safer and more compliant worksite but also a noticeable acceleration in advance rates, making the YT28 a smart investment that pays dividends in both safety and bottom-line performance.
