- Reduced cost for drilling tools: The hydraulic jumbo drill is equipped with high performance drifter. A dual damper mechanism ensures increased impact energy transfer efficiency. This results in high drilling performance. Combined with anti-jamming function, the service life of the drilling tools such as bits and rods is greatly prolonged.
- Improved working environment: The water is used for hole flushing during rock drilling, minizing dust generation. This provides a comfortable and safe working environment.
- High safety: FOPS certified operator’s cab insulates the operator from noise, dust and vibration, which provides great protection to the operator. This ensures accurate and speedy drilling jobs are performed in a safe manner.
- Cost effective choice: Our underground jumbo drills features high quality core drilling accessories, which guarantees stable operation and high productivity.
