Claim Text:
1. A method for detecting catastrophic failure of a man lift, comprising the steps of: sensing a pressure utilized to raise and lower the man lift using a sensor so as to provide monitored data; and, processing the monitored data for a change in the pressure while the man lift is in operation that would indicate the imminence of the catastrophic failure so as to provide an alarm indicative of the imminence of the catastrophic failure, whereby a man lift operator is lowered to safety before the catastrophic failure, the processing further includes the step of utilizing a prognostication algorithm for predicting the catastrophic failure, the prognostication algorithm determining when the pressures during the elevation of the man lift drop below a predetermined line or drop below a predetermined change indication an abrupt change to indicate the potential catastrophic failure.
