Heavy Duty YT27 Pusher Leg Rock Drill With High Impact Energy Low Air Consumption And All Weather Versatility For Underground Mining
The YT27 Pusher Leg Rock Drill is a high efficiency, heavy duty pneumatic jackhammer engineered for intense excavation projects. Weighing 27kg, this robust air leg mining drill delivers massive impact energy with low air consumption. It has earned its reputation as the top operator preferred choice in small scale mining operations and remains the leading model across primary mining markets, including South Africa and South America.
When integrated with the FY250C line oil lubricator and FT160A / FT160B air legs, the YT27 excels at wet drilling horizontal or inclined blast holes through medium-to-hard rock formations. Its adaptable design also allows it to be mounted directly onto drilling jumbo trolleys for automated infrastructure projects.

Key Advantages
High Impact Energy, Low Emission: Engineered to deliver a striking force exceeding 70J at 0.63MPa while maintaining optimized air consumption to cut down compressor fuel costs.
All Weather Versatility: Built with premium grade hardened alloy steel, the YT27 operates flawlessly in extreme environments ranging from sub-zero arctic mines (-30°C) to scorching tropical quarries (50°C).
Wet Drilling Technology: Features a centralized water flushing mechanism that suppresses airborne silica dust, ensuring a safer workspace and compliance with strict industrial health regulations.
Applications
The YT27 air leg rock drill is widely deployed in the following rock excavation sectors:
Mining Roadway Excavation: Crucial for drifting, cross cutting, and blast hole preparation in small to medium underground coal, gold, and copper mines.
Civil Infrastructure: Highly utilized in railway tunneling, highway rock cutting, and mountain road expansion.
Hydraulic Engineering: Essential for water conservancy projects, dam construction, and drainage tunnel boring.
National Defense: Tailored for milita underground bunkers, deep rock anchoring, and fortification engineering.
