Patent ID: 7921000

Claim:
A maintenance support system for a construction machine that comprises a computer system that is connected to the construction machine via a communication network, wherein the computer system comprises: an operation simulation means for simulating driving conditions and/or working conditions of the construction machine prior to the operation of the construction machine on the basis of production operating conditions that are input; a cumulative load calculation means for calculating a cumulative load relating to a predetermined component that is preset, on the basis of simulation results produced by the operation simulation means; and a lifespan calculation means for calculating a lifespan of the predetermined component on the basis of the cumulative load thus calculated, wherein the operation simulation means sets, for respective simulation models, a departure point of the construction machine, an arrival point of the construction machine, and at least one course that links the departure and the arrival points, each being designated by a production operating condition, in order to simulate, at predetermined times, driving conditions and/or working conditions of the construction machine in accordance with occurrence status of events associated with the departure point, the arrival point, and the course respectively.
