Abstract

A diagnostic device includes a first processor for diagnosing an abnormality of a travel device on the basis of a travelling feature amount representing a travelling state of the travel device mounted to a machine body of a work machine and an output device for outputting a result of a diagnosis performed by the first processor. The first processor acquires an inclination feature amount representing an inclination state of the machine body, computes a correction amount for canceling an influence of the inclination state of the machine body on the travelling feature amount of the travel device on the basis of the inclination feature amount, computes a corrected travelling feature amount by correcting the travelling feature amount on the basis of the correction amount, computes an abnormality determination evaluation value on the basis of the corrected travelling feature amount, determines whether or not there is an abnormality in the travel device on the basis of the abnormality determination evaluation value, and outputs, when it is determined that there is an abnormality, relevant determination result to the output device.
