作業車に於ける作業台の垂直制御装置。 In an aerial work vehicle comprising a boom that is movable and telescopically attached to a turntable mounted on a trolley, etc., and a work platform for performing a predetermined work on the boom, Equipped with an attitude control mechanism, a predetermined control signal is input to the attitude control mechanism so that the work platform on the boom can be moved along the work surface, etc., and the boom's elevation angle is detected at an appropriate position on the boom. and a boom extension/contraction length detector, and the detection signals obtained by these detectors are input to a comparison circuit constituting the attitude control mechanism, and compared with a undulation reference value signal inputted in advance to the comparison circuit. When the detection signal (detection angle) by the undulation angle detector is larger than the undulation reference value signal (set angle), a contraction signal is output to the telescopic cylinder;
A vertical control device for a work platform in an aerial work vehicle, characterized in that when the retraction of the boom is detected by the telescopic length detector after that, a lowering signal is output to the lowering cylinder. .
