Abstract

An object is to ensure posture stability of a work machine by taking into account the effect of a cliff-like terrain on the posture stability of the work machine. The work machine includes a posture detection device that detects an inclination angle of the work machine and a swing angle of an upper swing body; a surrounding detection device that detects a surrounding terrain; and a controller that controls the work machine. The controller includes: a cliff determination section that determines whether a bench edge exists around the work machine based on a detection result of the surrounding detection device; a center-of-gravity calculation section that calculates a center-of-gravity position of the work machine based on a detection result of the posture detection device; and a stabilization assistance section that assists in posture stabilization of the work machine. If a distance between the bench edge and the center-of-gravity position is equal to or less than a threshold, the stabilization assistance section causes a notification device to issue an alert or restricts an operator operation that will cause the center-of-gravity position to approach the bench edge, as assisting in the posture stabilization.
