<p>The operation hours of the engine (32), front (15), pivot cab (13), and traveling gear (12) of a hydraulic shovel (1) operated on the market are measured. The data is stored in a memory of the controller (2), transferred to a base station computer (3) through satellite communication or an FD, and stored in a database (100). The base station computer (3) calculates, stores, and accumulates the operation time interval of each component of each portion of each hydraulic shovel on an operation hour base of the portion by using operation data every time the component is replaced for repair, reads the data for each hydraulic shovel, calculates the replacement rates of components the replacement time intervals of which are almost equal to that of each component, and the target replacement time interval of the component from replacement time interval corresponding to the maximum replacement rate. Thus an appropriate target replacement time interval can be determined, and an appropriate replacement scheduled time can be determined even if the component is of a portion having different operation hours.</p> |
