An overload preventing device is provided which, while ensuring safety, allows maximum utilization of lifting performance of a work machine depending on the operating state. This overload preventing device is mounted on a mobile work machine, and is provided with: a storage unit which stores lifting performance data in which lifting performance is configured for each operation state, and performance region data in which switching angles are configured that define performance regions, including a front region, a back region, and a side region; and a work machine control unit which controls operation of the mobile work machine on the basis of the actual load and the lifting performance corresponding to the present operation state of the mobile work machine. A third lifting performance configured for a transition region, a first switching angle defining the boundary between the front region and the side region and the boundary between the back region and the side region when the outriggers are in different states of deployment, and a second switching region defining a transition region in the side region are configured on the basis of stability calculations and strength factors such as jack strength.
