ン車あるいは高所作業車に用いられる安全装置。[Scope of Claim for Utility Model Registration] A safety device for use in crane vehicles or aerial work vehicles, which comprises a telescopic boom that can be driven up and down, and a hook that is driven to be raised and lowered by an appropriate means is attached to the tip of the boom, A moment detecting means for detecting a moment acting on the telescopic boom, a boom attitude detecting means for detecting the heave angle and telescopic length of the telescopic boom, and a detection value detected by the moment detecting means upon receiving signals from both of these detecting means. A system equipped with a calculation unit that outputs a stop signal to disable the telescopic boom's lodging, extension, and hook hoisting movements when a limit value determined based on the telescopic boom's posture at that time is reached. An elevating operation detection means that outputs an elevating operation signal when an elevating operation is performed is installed, and the output of this elevating operation detecting means is input to the calculation unit, and the calculating unit When the detection value detected by the moment detecting means reaches a limit value determined based on the posture of the telescopic boom at that time while an operation signal is being input, in addition to outputting the stop signal, the telescopic boom is raised and raised. A safety device for use in a crane vehicle or an aerial work vehicle, characterized in that it is equipped with a boom raising/lowering stop signal output means for outputting a boom raising/lowering stop signal to disable the boom.
