CABLE, SCREENED

884 245 69A CABLE, SCREENED This cable connects the speed sensor, typically located on the drifter's rotation unit, back to the main control cabinet. It carries the electrical signal that tells the control system exactly how fast the drill string is turning. This RPM data is critical for the system to automatically adjust feed pressure and rotation torque, ensuring efficient rock breaking and preventing the bit from getting stuck.

An unreliable signal from a damaged cable can cause serious drilling issues. The operator might see fluctuating RPM readings on the display or get fault codes that stop the operation. Without this feedback, automated drilling functions are compromised, leading to a lower rate of penetration, excessive wear on the drill bit, and potential downtime while troubleshooting the electrical system.

When troubleshooting, visually inspect the cable for cuts, abrasion, or pinch points, particularly along the feed beam and boom where movement is constant. Check that the connectors at both ends are clean and securely fastened. During replacement, ensure the new cable follows the intended routing to avoid being stretched or crushed during operation.
