とを特徴とする高所作業車のアウトリガ装置。 In an aerial work vehicle equipped with an appropriate number of outrigger devices at appropriate positions on the vehicle body, an outrigger beam is arranged so as to be retractable from an outrigger box constituting the outrigger device, and a through hole is formed at the end of the outrigger beam. A jack box having a jack post arranged therein which can be retracted is pivotally supported at the end of the outrigger beam so as to be rotatable at a predetermined angle, and the jack box is provided at the end of the outrigger beam on the side of the upper vehicle body. A bracket equipped with a stopper pin that engages and disengages from the through hole of the stay is attached, and a hydraulic cylinder having a rotation fulcrum on the stay is attached to the side of the jack box, and the rod end of the hydraulic cylinder is implanted in the bracket. A ring provided with a play hole that engages with the pin is attached, a protrusion is provided on one side of the ring to abut a lever connected to the stopper pin, and the lever is rotated by a predetermined angle according to the amount of movement of the protrusion. An outrigger device for an aerial work vehicle, characterized in that the stopper pin is engaged with and disengaged from the through hole, and the jack box is rotated by a predetermined angle by the expansion and contraction movement of the rod of the hydraulic cylinder.
