Patent ID: 8533018

Claim:
A construction machine maintenance work management system which manages, between a plurality of construction machines, maintenance tasks for exchanging components installed to the construction machines, comprising: said construction machines, and said components including at least one of a transmission, a hydraulic pump, and a metal part of an engine; a first service life prediction unit which predicts first service lives of said components, based upon changes of first parameters in which wear states of said components are reflected over time and according to a compensation coefficient based upon test data for a previous component of said components; a second service life prediction unit which predicts second service lives of said components, based upon second parameters in which cumulative load amounts of said components are reflected over time and lifetime cumulative load amounts which are set in advance; an order setting unit which selects, as service lives of said components, the ones which are the shorter among said first predicted service lives and said second predicted service lives, and which sets an order for the maintenance tasks between said plurality of construction machines so that maintenance is performed upon each of said components which said plurality of construction machines possess, in an order beginning from that construction machine which has the one of said components whose life is the shortest among said selected lives; and a maintenance schedule generation unit which generates a maintenance schedule for said components, based upon said order which has been set.
