BOOM DIR ANGLE IND.

177 406 48 BOOM DIR. ANGLE IND. SENSOR Mounted on the drill feed or boom assembly, this angle indicator measures the precise tilt and rotation of the drilling axis. Its function is to translate the physical position of the feed into an electronic signal for the rig's control system. This information is essential for the operator to accurately align the drill for each hole in the pattern, which is fundamental for productive and safe mining.

An inaccurate or failed angle sensor directly impacts drilling quality. If the operator receives incorrect angle data, the resulting blast pattern will be compromised, potentially leading to poor fragmentation and difficulties in the mucking cycle. Consistent, reliable angle measurement prevents costly rework and ensures the excavation profile matches the mine's engineering design.

Symptoms of a failing indicator include erratic readings on the cabin display, a complete loss of the angle value, or a persistent error code. Before replacement, check the electrical connector for moisture or damage. If the unit itself is faulty, it should be replaced and the system recalibrated to ensure accuracy.
