Atlas Copco offers Robbins 123RH C which is a powerful raise drill. It is suitable for use in large diameter and long hole raise boring applications. It can be used as sinking shafts in civil engineering applications or mining applications since it is designed for use in large diameter raises ranging from 3.1 to 6.0 m.
The key features of the Robbins 123RH C are:
- A sliding fork worktable wrench is used in combination with the semi-automatic drivehead wrench, thus avoiding the use of heavy wrenches
- Dual hydraulic pumps for ensuring high machine availability
- A gearbox can be included in a barrel for dismantling the drive train into smaller components without reducing the preload of the main bearings, thus saving transportation and maintenance time.
