YT28 High Efficiency Pusher Leg Rock Drill With 63 Joules Impact Energy And Ergonomic Anti Vibration For Mining Tunneling
The YT28 Pusher Leg Rock Drill is a next-generation, high-performance pneumatic drifter engineered for supreme efficiency in harsh geological conditions. Characterized by its massive impact energy and low operational vibration, this 26kg industrial jackhammer maximizes drilling speed while minimizing operator fatigue. It stands as an indispensable tool for heavy duty applications across metallurgy, coal mining, railway construction, and national defense engineering.
Designed for ultimate adaptability, the YT28 excels at boring horizontal, inclined, and vertical roof bolting holes in medium to ultra-hard rock formations (hardness scale f=8-18). Depending on your tunnel cross section requirements, this pneumatic drill pairs seamlessly with FT160BD (short), FT160BC (long), or FT160S (telescopic double stage) air legs, and can also be integrated into automated drilling jumbo rigs.
