The present invention relates to a hydraulic breaker with a magnetic sensor for sensing the loosening and damage of a long bolt, which can sense the loosening or damage of a long bolt for combining a component by being mounted at a main body, due to vibration or impact and can prevent degradation of a hydraulic breaker. The hydraulic breaker comprises: multiple hexagonal nuts (450) where a magnet (510) is inserted into a groove formed on one side and which fixate the top of a long bolt (440); multiple magnetic sensor mounting holes (520) which are formed on a head cap (410); and multiple magnetic sensors (460) which are mounted on the magnetic sensor mounting holes (520). Therefore, the hydraulic breaker with a magnetic sensor for sensing the loosening and damage of a long bolt can inform an operator of the loosening or damage of the hexagonal nuts where the magnet is inserted, through sound or light by detection of the magnetic sensors, so that the operator can easily recognize the loosening or damage of the hexagonal nut, and can extend the life cycle thereof by properly performing repair of the hydraulic breaker in use. |
