Rod Adding System, RAS (Optional)

RAS is a mechanized rod adding system used for drilling of which the second rod is placed on the feed by the grippers.

The drilling cycle starts with one SPEEDROD in the feed
and another in the gripers. When the first rod is drilled into
the rock, the drill steel support gripps the rod at the coupling
end and the rod is uncoupled. The rockdrill reverses after
