ABSTRACT:
This invention is generally directed towards a system designed to assist the rig operator by alerting him/her that the air pressure is too low to be using the drum clutch, to provide a log for studies on rig operation technique, and to provide a training tool for rig operators. If the pressure on the clutch bladder is above a predetermined range, the clutch is allowed to engage. If the signal is below the range, the clutch is assumed to have not been engaged. If the signal is within the range, the clutch is not allowed to engage and the rig operator is notified of the problem.
