  • Rollover prevention system and method for construction machine
    Patent number: 11015320
    Abstract: A rollover prevention system prevents a construction machine from rolling over. The rollover prevention system comprises a first angle detection unit (12) disposed adjacent to a turning joint (11) to detect a swing angle of the upper frame (5), a second angle detection unit (13) disposed on the upper frame to detect an angular movement of the upper frame, safety valves (40) disposed on flow passages (25, 32) communicating with hydraulic cylinders for a work attachment (10) and a swing motor (26) to control flows of working oil supplied to the hydraulic cylinders by opening and closing the flow passages in response to external signals, and an electronic controller (14) electrically connected to the first angle detection unit, the second angle detection unit, and the safety valves. The electronic controller comprises a barycenter calculating section (14a), a safety range determining section (14b), and a signal outputting section (14c). A rollover prevention method for a construction machine is also provided.
