安全装置。[Claims for Utility Model Registration] A hoisting boom is provided on the vehicle body and is rotatable relative to the vehicle body, and a working device is provided at the tip of the hoisting boom and is capable of horizontally swinging relative to the hoisting boom. A safety device for a boom work vehicle comprising: an overturning branch line calculation means for calculating an overturning branch line of the vehicle body; and an actual overturning direction moment acting on the vehicle body in response to operation of the boom reaches a predetermined limit value. regulation signal generating means for generating an operation regulation signal when the regulation signal is generated; and when the regulation signal is generated, a oscillation that connects the center of swing of the working device at the tip of the hoisting boom and the center of gravity of the working device in plan view. A safety device for a boom work vehicle, comprising a swing regulating means for regulating the swing of the working device in a direction in which the axis of motion approaches a state where the axis of motion approaches the overturning branch line orthogonally.
