A lifting load and tipping moment detecting device for a mobile crane for detecting a lifting load and a tipping moment with high accuracy, thereby making it possible to use an excessive load prevention system effectively while ensuring safety. For this reason, sensors (50, 48, 46) are provided for detecting the boom length, boom angle and shaft weight of a boom hoisting cylinder (26) on the side of a second boom (28), respectively, and a controller (38) is also provided for operating a lifting load (Wa) suspended from the second boom (28) based on signals from those sensors. In addition, a boom length sensor (44) and a boom angle sensor (42) on the side of a first boom (24) are provided for operating a tipping moment.
