The hydraulic controlled drilling system with added
automatic functions and different optional instrumentation levels enable productive and high quality excavation. Built-in diagnostics help to minimize maintenance
time.
The HLX5 rock drills deliver superior performance with
high consumable life.
The TB 60 universal booms have a large optimum
shaped coverage and full automatic parallelism.
The booms can also be used for cross-cutting and bolt
hole drilling.
The powerful 4-wheel-drive center articulated carrier
ensures rapid and safe tramming with good balance.
