A maintenance support system for a construction machine, capable of accurately planning a maintenance plan for parts. With this system (1), after operation simulation means (12) simulates a condition of operation and work of a construction machine (3) based on a condition of operation for production, load calculation means (13) calculates for each part an accumulated load according to the condition of operation and work, and then life calculation means (14) estimates the life of each part based on the accumulated load. More accurate maintenance plan can be established than in a conventional method where which part is to be maintained is determined based on only operation hours. As a result, possibility where sudden part failure occurs at a stage before an estimated life end can be reduced. |
