Mountain tunnels often involve unstable rock formations. The YT28 offers dependable penetration with reduced vibration, making it easier to control hole direction on inclined tunnel faces.

 

Its wet drilling function supports cleaner working environments and helps manage dust where tunnel ventilation is limited.

 

The YT28 air leg rock drill is a robust pneumatic drilling tool engineered for tough mountain tunnel environments. Designed with a stable impact frequency and reduced vibration, it delivers reliable penetration while maintaining precise hole alignment even on steep or inclined surfaces. The drill features a wet drilling function, which suppresses dust and keeps the worksite cleaner—a critical advantage in confined tunnels with limited ventilation. Operators simply connect the machine to a standard air supply, attach the water hose for dust control, and position the leg support to begin drilling. With intuitive controls and durable construction, the YT28 requires minimal training to operate and is built to withstand harsh rock formations.

 

Before introducing the YT28, many tunneling teams relied on older, less efficient rock drills that struggled with directional stability on sloping faces. Drillers often experienced slower advance rates, higher deviation in blast holes, and excessive dust accumulation, leading to frequent work interruptions and increased respiratory risks. Since switching to the YT28, contractors report noticeably faster drilling cycles, improved accuracy in hole placement, and a healthier site environment thanks to the integrated wet drilling system. The machine’s consistent performance in unstable rock has reduced realignment efforts and helped crews meet tight project timelines with greater confidence.

 

We are a dedicated rock drilling machinery manufacturer with decades of experience in designing and producing durable, job-ready equipment for mining and tunneling. Our focus is on creating tools that address real onsite challenges—like unpredictable geology, dust control, and operator fatigue. The YT28 exemplifies this approach, developed after extensive feedback from drillers working in mountainous terrain. Every component is selected for endurance, ease of maintenance, and compatibility with standard job site setups.

 

For tunnel engineers and drilling supervisors, the YT28 brings a balance of power and control that is often missing in conventional rock drills. Its ability to hold a true course on inclines means fewer wasted holes and more efficient blast patterns. The wet drilling feature not only meets modern safety expectations but also extends drill steel life by reducing heat and wear. In remote tunnel projects where equipment reliability can make or break progress, the YT28 has proven itself as a workhorse that keeps crews moving forward with fewer stoppages.

 

We invite tunneling contractors and mine operators to experience the difference that purpose-built drilling equipment can make. The YT28 is more than just another rock drill—it’s a productivity partner engineered for the demands of steep, unstable, and dusty tunnel faces.
