Quality boosting automation features
FAM III with digital drill plans
Feed Angle Measurement (FAM III) is an operator assist function that enables the use of digital drill plans with the help of positioning and angle data from sensors on the boom and feed joints.
Total station navigation
Navigating a drill rig with the Total station provides a positional accuracy of 1 cm in all axes (x, y, and z), ensuring high drilling precision according to the digital drilling plan and accurate alignment with the tunnel line.
Measure While Drilling
Drill parameters are collected to give information about rock conditions. Collecting MWD data is even mandatory in certain cases. These parameters are used to calculate, predict and evaluate rock conditions such as rock hardness and fracturing.
