。 In an aerial work vehicle equipped with a boom that can be raised, retracted, and rotated via a turntable on a chassis equipped with multiple outriggers, the amount of overhang of adjacent overhangs among the overhang amount detectors installed on the outriggers. The detection signal detected by the detector and the detection signal detected by the boom rotation angle detector are inputted into a working range calculator, and the working range calculator calculates the distance between two adjacent outriggers with at least one outrigger as a reference. At the same time, on the intersection line of the work restriction range determined by each outrigger, the boom rotation restriction valve is operated to control the boom rotation to the left or right. A boom rotation regulating device for an aerial work vehicle characterized by preventing the boom from rotating to the side.
