Patent ID: 6907384

Claim:
A method for managing a construction machine, the method comprising: a first step of measuring a working time for each section in each of a plurality of construction machines, and storing and accumulating the measured working time as operation data for each construction machine in a database; a second step of determining, based on repair/replacement data for each part of the construction machine and said operation data, an actual repair/replacement time interval of each part on the basis of the working time per section to which the relevant part belongs; and a third step of statistically processing the actual repair/replacement time interval and setting a target repair/replacement time interval of the relevant part to be used for deciding a scheduled repair/replacement timing of a corresponding part of the particular construction machine using the statistically processed data and wherein: said third step further includes steps of determining a relationship between the actual repair/replacement time interval of a part determined in said second step and the number of times of actual repair/replacement of said part, determining a repair/replacement time interval corresponding to a maximum number of times of repair/replacement from said relationship, and deciding the target repair/replacement time interval of said part based on the determined repair/replacement time interval.
