Abstract

Provided is a hydraulic shovel (1) constituted by multiple components, comprising: a storage device (20) which stores an operation history of a target component, which is a component included in the multiple components and for which a life span is to be estimated, a discrimination threshold value used for classifying a usage mode of the target component into one of multiple modes on the basis of the operation history, and usage mode-specific estimated life spans which indicate estimated life spans of the target component for the respective usage modes; and an arithmetic and control unit (10) for executing a process of calculating the operation time of the target component for each usage mode on the basis of the discrimination threshold value and the operation history of the target component, and a process of estimating the life span of the target component on the basis of the operation time of the target component for each usage mode calculated in the aforementioned process and the usage mode-specific estimated life spans. This can improve the estimation accuracy of the life span of a component relating to an operating 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 ...
