Abstract: Systems, methods, and computer program products can determine wear, damage, change, or other characteristics of a portion of a front linkage of an excavator. The systems, methods, and computer program products can comprise determining, based on signals from at least one sensor of the excavator, that the excavator is in a predetermined state to weigh at least a portion of the front linkage of the excavator; determining a weight of the portion of the front linkage of the excavator under a condition that the excavator is in the state to weigh the portion of the front linkage of the excavator; determining that the determined weight of the portion of the front linkage is outside of a predetermined weight range; and electronically outputting information regarding a further action to be taken with respect to the portion of the front linkage of the excavator.

Abstract: This disclosure describes, in part, systems and techniques for monitoring linkage joints of machines, such as earth-moving machines, using on-board sensors of the machines to identify linkage joints at risk of galling. The systems and techniques involve gathering sensor data and determining a galling risk score for each linkage joint. The galling risk score may then be used to alert an operator and/or maintenance system to determine when to take remedial action and/or perform maintenance while also avoiding costly downtime from galling failures.
