グ装置。[Scope of Claim for Utility Model Registration] The vehicle is equipped with a bendable boom consisting of a lower boom that is attached to the vehicle body so that it can be raised and lowered, and an atsupah boom that is attached to the tip of the lower boom so that it can be bent and extended. A leveling device for an aerial work vehicle comprising a movable work platform, comprising a leveling cylinder for vertically swinging the work platform and holding it horizontally, and a levitation angle for detecting the undulation angle of the lower boom. a detector; a bending/extending angle detector that detects a bending/extending angle between the lower boom and the up/down boom; and calculating a bending/extending angle of the up/down boom with respect to the horizontal direction based on the angles detected by the undulation angle detector and the bending/extension angle detector. and a leveling controller that sets the operating direction of the leveling cylinder based on an increase/decrease in the bending/extending angle of the upper boom with respect to the horizontal direction accompanying the operation of the bending/extending boom.
