Abstract: An operation record analysis system for a construction machine is provided which can efficiently extract work contents that may possibly make a factor of decrease in the operation rate from within operation information recorded at the time of operation of a construction machine. The operation record analysis system for a construction machine includes an object sensor that senses an object existing around a machine body. A controller calculates the position of the object on the basis of the information from the object sensor, decides, on the basis of the information from a machine body position sensor and a machine body posture sensor, and the position of the object, whether or not the machine body and the object are close to each other, and adds a result of the decision to the operation information.

Abstract: Every time the haulage vehicle position data and the road surface condition data are received from a haulage vehicle 120, the segment including a position specified by the haulage vehicle position data, a reception time, and the road surface condition data are associated with one another for accumulation. Every time the repair vehicle position data and the work status data indicating a working state are received from a repair vehicle 130, the road surface condition data associated with the segment including a position specified by the accumulated repair vehicle position data is reset. Every time the road surface condition data is newly accumulated, a prediction function is determined to predict a chronological change in road surface conditions of the segment based on the road surface condition data accumulated on a segment-by-segment basis and a repair scheduled time-of-day is calculated according to the prediction function to output to an output apparatus.
