Abstract:
The objective of the present invention is to provide a hydraulic breaker comprising: a hydraulic breaker body part; a sensor part sensing vibration generated in the hydraulic breaker body part when objects to be crushed, including bedrocks, are crushed, so as to output a sensing signal; and a control part receiving the sensing signal so as to calculate the time for which the hydraulic breaker body part vibrates, thereby calculating an operating time.
