<P>PROBLEM TO BE SOLVED: To accurately grasp the maintenance times of consumable parts of a construction machine. <P>SOLUTION: This maintenance information management device comprises a storage means 56 for accumulating and storing representative values representing the loads of the consumable parts detected while specified operations are performed and a deriving means 56 for deriving the information on the maintenance times of the consumable parts according to the representative values of load accumulated and stored in the storage means 56. The storage means 56 accumulates and stores the moment times based on the moments as the product of the working radius of the operation and a lifted load and a working time and the working times as the representative values of load of hydraulic hoses to which a load is applied by a lifting operation or a boom derricking operation. <P>COPYRIGHT: (C)2008,JPO&INPIT |
