Abstract (en)

A safety device includes: a contour sensor (101) which acquires contour data representing a contour of a landform around a hydraulic excavator (1); a determination part (112) which determines, based on the contour data, whether the landform satisfies an execution criterion of executing a turning-over prevention control for preventing the hydraulic excavator (1) from being turned over to a slope extending in a specific direction therearound; and a lowering control part (113) which lowers a leading end of a working device to the slope when the determination part (112) determines that the execution criterion is satisfied.
