• Optimized Power to Weight Ratio : The YT29A integrates an advanced structural design where impact energy and strike frequency are precisely calibrated. This synchronization delivers maximum destructive force with minimal operator fatigue.
• Accelerated Penetration Rates : Engineered for speed, this air leg rock drill drastically shortens drilling cycles, boosting daily footage and operational throughput.
• Heavy Duty Lubrication System : Equipped with the high capacity FY250 lubricator, the internal moving parts receive continuous, ultra strong oiling. This significantly extends the machine's lifespan and reduces maintenance downtime during extended shifts.
• Ergonomic Control  Noise Reduction : Featuring a centralized control handle integrated into the back head, operators can manage air and water with ease. Additionally, an adjustable muffler cover lowers decibel levels and allows directional exhaust control, drastically improving on-site safety and working conditions.

The YT29A pneumatic drifter is highly versatile, built to adapt to various working heights, roadway cross sections, and mounting configurations.

To match diverse tunneling profiles and space constraints, the YT29A perfectly couples with multiple pusher leg models :

• FT160A / FT160B / FT160C (Standard to compact tunnel setups)
• FT170 (Extended reach and heavy thrust conditions)

Whether managing a deep world mining operation or a precision civil engineering project, the YT29A pusher leg rock drill excels in creating horizontal, inclined, or upward/downward anchor holes for :

1. Underground Mining  Metallurgy : Driving galleries, production blasting, and installing roof bolts.
2. Tunneling Subway Construction : Efficient excavation for railway, highway, and municipal transit tunnels.
3. Hydropower Water Conservancy : Drifting injection holes, dam reinforcement, and rock scaling.
4. Quarrying Stone Works : Heavy duty block splitting and bench drilling.
