Abstract
To provide a walking type work machine capable of coping with an unexpected movement without depending on a dead man type clutch.SOLUTION: A walking type work machine includes a machine body, a sensor for detecting the state of the machine body, a control device for acquiring output of the sensor, and a controlled device whose operation is controlled by the control device. The control device determines the state of the machine body on the basis of output of the sensor, executes first control, which is the control at the normal time, for the controlled device when determining that the machine body is in a usual first state, executes second control, which is the control at the warning time and different from the first control, for the controlled device when determining that the machine body is in a second state in which the possibility of abnormality is higher than in the first state, and executes third control, which is the control at the abnormal time and different from the first control and the second control for the controlled device when the second state continues exceeding a predetermined time.SELECTED DRAWING: Figure 4
