Abstract

A hydraulic excavator (1) composed of a plurality of parts includes a storage device (20) for storing work histories of a target part included in a plurality of parts and used for life estimation based on the work history. The usage method of the target part is classified into a plurality of discrimination thresholds, and each usage method estimated life indicating the estimated life of the target part for each of the usage methods; The process of calculating the operating time of the target part for each usage method based on the history and the discrimination threshold value; and estimating the life of the target part based on the operating time of the target part for each usage method calculated by this process and the estimated life of each usage method processing. Accordingly, it is possible to improve the estimation accuracy of the service life of parts in the work machine.

Description

technical field [0001] The present invention relates to a working machine and a maintenance inspection information generating device for providing information related to maintenance of the working machine based on an operating state of the working machine. Background technique [0002] Industrial operating machines represented by construction machines have a large impact when they stop due to failure, etc. Therefore, preventive maintenance measures are often taken to keep the machine in the best condition through maintenance. Maintenance is generally a regular maintenance mainly based on the working hours, and the inspection or repair or replacement of each part determined by the design standards is carried out according to the working hours of the machine. [0003] If preventive maintenance is carried out, the machine will be kept in good condition, so failure should not occur, but failure and stoppage cannot be avoided in reality. For example, if a machine is used with a ...
