|
ROC L6(25) and L6(30) are high-capacity down-the-hole crawlers for quarry drilling in soft, medium and hard rock, with Atlas Copco screw type high pressure compressors that delivers compressed air at full 25 and 30 bar. With the powerful CAT C11 and CAT C13 diesel engines the ROC L6 not only provides power, but economy. |
| Main benefits |
- Productivity beyond conventional rigs using DTH (Down-The-Hole hammers)
|
- Efficient utilisation of hammer capacity through a unique cylinder feed system
|
- Transport configuration which makes the rig ideal for single or multi site operations
