The system includes: a data recording device (30) arranged in a construction machine such as a hydraulic shovel (1) and processing an operation time or date and time;

It is an important factor for the perfect matching between the maximal input power of the hydraulic oil pump and the maximum output power of the engine in the design process of the hydraulic shovel.
