ANGLE INDICATOR ASSY

239 431 58 MEC. ANGLE INDICATOR ASSY This angle indicator is a sensor that measures the orientation of the drill feed or boom. Its primary job is to send precise tilt and swing angle data to the rig's control system or the operator's display. Accurate angle information is essential for automated drilling cycles and for following the complex patterns required in modern tunneling and mining.

A malfunctioning angle sensor can directly impact the entire operation's efficiency. If the sensor provides a faulty reading, the entire drill pattern can be misaligned, leading to poor blasting results, incorrect tunnel profiles, and costly rework. It also compromises the effectiveness of any automated features, forcing operators to rely on manual alignment, which slows down the drilling cycle.

Symptoms of a failing indicator include erratic or frozen angle readings on the cabin display, or frequent control system alarms related to positioning. Before replacement, check that the sensor's electrical connector is clean and secure. If the problem persists, the unit should be replaced and the new sensor must be calibrated using the procedure in the machine's service manual to restore drilling accuracy.
