CHASSIS DEVI

CHASSIS DEVI 5740 2503 87 Serving as the structural foundation for the hole alignment system, this chassis holds and protects the critical electronic sensors used for deviation measurement. It is typically mounted on the feed beam, providing a stable reference point for the instrument as it guides the drill string. Its primary job is to shield the sensitive internal components from the vibration, impacts, and contamination common in underground operations.

Drilling accuracy depends heavily on the integrity of this housing. If the chassis is bent from an impact or has worn mounting points, the deviation sensor will provide false readings. This leads to out-of-tolerance holes, which can result in poor fragmentation during blasting and create operational challenges for the next stage of the mining cycle. A secure, undamaged chassis is essential for reliable and predictable drilling results.

Check this chassis for any visible cracks or deformation during routine walk-around inspections, especially after any incidents of the boom hitting the tunnel wall. Inconsistent angle readings or frequent calibration faults on the operator's screen can also point to a problem. If damage is found, replacement is necessary to restore drilling precision and prevent costly damage to the internal instrument.
