Abstract:
A drilling rig control system adapted for easy interface between a compressed air supply and a drilling rig clutch and brake. Both manual and automatic controls are provided to initiate the device to interrupt and vent the compressed air supply to the clutch and concurrently communicate compressed air to the brake to cause it to engage the drum winding the cable for the rig. Over-pull sensors monitor cable tension and initiate valves in the control system to initiate the compressed air interruption and rerouting upon any sense of over-pull.
