Abstract: According to an aspect of the present invention, an information output method for a construction machine executed by one or more hardware processors includes detecting the condition of an inspection target of the construction machine with an information obtaining device. The cumulative operating time of the inspection target or the diagnosis result of the condition of the inspection target is determined based on the detection result. A maintenance price associated with the cumulative operating time or the diagnosis result is determined and output.

Abstract: A hydraulic shovel includes: a storage unit which stores an operation history of a target component of the shovel targeted for life span estimation, a discrimination threshold value used for classifying usage of the target component into a plurality of usage modes based on the operation history, and a usage mode-specific estimated life span indicative of an estimated life span of the target component in each of the usage modes; and an arithmetic and control unit which calculates an operating time of the target component in each of the usage modes in accordance with the operation history and the discrimination threshold value, and estimates the life span of the target component based on the operating time calculated for each of the usage modes and on the usage mode-specific estimated life span.

Abstract: A hydraulic shovel (1) constituted by a plurality of components includes: a storage unit (20) which stores an operation history of a target component included in the plurality of components and targeted for life span estimation, a discrimination threshold value used for classifying usage of the target component into a plurality of usage modes based on the operation history, and a usage mode-specific estimated life span indicative of an estimated life span of the target component in each of the usage modes; and an arithmetic and control unit (10) which performs a process of calculating an operating time of the target component in each of the usage modes in accordance with the operation history of the target component and the discrimination threshold value, and a process of estimating the life span of the target component based on the operating time of the target component calculated for each of the usage modes in the aforementioned process and on the usage mode-specific estimated life span.
