This overload preventing device is mounted on a mobile work machine, and is provided with: a storage unit which stores lifting performance data; 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.
