The YT27 air leg rock drill is a high-performance pneumatic drilling machine designed for demanding mining and construction applications. This robust equipment features exceptional hole-cleaning capability and high torque rotation for efficient brazing operations.
Engineered with advanced functionality, the YT27 model incorporates a flange control valve system for superior gas production and distribution. Its innovative design makes it particularly suitable for large-scale mining operations and roadway construction projects where reliability and performance are critical.
The drill features several user-friendly mechanisms including air-water linkage, quick-return air-leg functionality, and adjustable air pressure controls. All control handles are ergonomically positioned around the main handle for convenient operation. The integrated sound-deadening cover significantly reduces operational noise while allowing flexible exhaust direction adjustment, improving overall worksite conditions.
Key application areas include:
- Railway construction and maintenance
- Tunnel excavation projects
- Highway development
- Metallurgical mining operations
- Coal mining applications
- Water conservancy and hydropower construction
For optimal performance and safety, proper pre-operation procedures should be followed:
1. Conduct thorough inspection of all components including the rock drill, support brackets, and cart systems
2. Verify proper lubrication and check all air/water connections
3. Examine the work area for loose rocks or unstable surfaces
4. Prepare drilling surfaces by leveling potential contact points
5. Always operate with water injection (wet drilling) - dry drilling is prohibited
6. Maintain proper body positioning during operation without applying direct physical pressure
7. Monitor for abnormal sounds or water discharge patterns
8. Exercise caution during bit changes or withdrawal operations
