とを特徴とする高所作業車の安全装置。 In an aerial work vehicle equipped with a work platform swingably mounted at the end of a boom that can be raised and lowered, and equipped with a work range regulation device, a detection device is provided to detect the swing angle of the work platform, and the work range regulation device is installed. When the safety limit work radius is reached by the device, the work range regulating device controls the control unit to disable at least the swinging operation of the work platform in a direction in which the overturning moment increases based on the detection result of the detection device. A safety device for an aerial work vehicle characterized by control.
