Abstract

A monitoring system for a hydraulic shovel, including strain and pressure gauges at critical locations on at least a boom or stick of the hydraulic shovel at which a failure is predicted to occur; a processor with memory hardware configured to process the acquired real-time data from the gauges to determine measures of actual instantaneous stress or accumulated damage and a real-time operating state; an output device configured to provide information comparing measures of actual instantaneous stress or accumulated damage with corresponding reference values of maximum allowable stress or accumulated damage, and to provide the real-time information derived from the real-time operating state. The real-time information derived from the real-time operating state includes a warning when one of the measures of actual instantaneous stress or accumulated damage exceeds or approaches the corresponding reference value, and programmed advice of appropriate corrective action having regard to the real-time operating state.
