Product Description

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.

Key Benefits

Eco Friendly Energy Savings: Advanced internal porting geometry optimizes compressed air delivery, yielding high penetration rates with minimal volumetric air consumption.
Aggressive Hard Rock Penetration : Delivers a heavy impact force of over 63J per blow, allowing effortless drilling through high abrasion stone barriers.
Ergonomic Anti Vibration Design : Built with cutting edge shock dampening components that absorb repetitive recoil, ensuring precise control and lowering the risk of operator injury.
Streamlined Maintenance : Features a re - engineered front head setup allowing rapid, tool free clearing of air and water flushing paths to prevent internal clogging.
Industrial Durability : All critical internal components are machined from heat treated alloy steel to ensure extended service life under continuous heavy shifts.

Primary Industrial Applications

Underground Mining Drifting : Ideal for driving development headings, cross cuts, and production blasting holes in deep gold, copper, and iron mines.
Roof Bolting Ground Support : Uniquely capable of drilling vertically upwards to install roof bolts, securing loose strata in tunnel ceilings.
Civil Hydraulic Infrastructure : Extensively utilized in highway rock cutting, high speed rail tunneling, dam foundations, and water conservancy projects.
