Abstract
A method and system for managing a construction machine and processing apparatus therefor includes a controller 2 mounted on a hydraulic excavator 1 working in fields. An operating time for each of an engine 32, a front 15, a swing body 13 and a travel body 12 is measured and stored in a memory of the controller 2. The measured data is transferred to a base station computer 3 and stored in a database 100 inside the base station computer 3. The base station computer 3 reads, per hydraulic excavator, the data stored in the database 100 and then prepares and outputs a distribution graph of the number of operated machines with respect to the working time (engine running time) of the hydraulic excavator. While looking at the distribution graph, a machine maker estimates the number of hydraulic excavators to be renewed and estimates the sales quantity of hydraulic excavators, thereby setting up a production plan of hydraulic excavators.
