動制御装置。 In an aerial work vehicle equipped with a multi-stage boom on the vehicle body having a work platform capable of swinging at the tip, a hydraulic cylinder for extending and retracting the multi-stage boom, a hydraulic cylinder for luffing, a hydraulic motor for swinging, and a hydraulic pressure for swinging the multi-stage boom. An electromagnetic control valve that controls each cylinder or hydraulic motor, a detection means that detects the extension/contraction length, undulating angle, swing angle, and swing angle of the multi-stage boom, and vertically rising and horizontally moving, which are arranged in the operating section. A left/right movement operating lever, an operating device that outputs an operating signal corresponding to the operation of each operating lever, a detection signal from each of the detection means, and an operating signal from the operating device, that is, the operating direction of the operating lever is vertically upward. or if below, raise or lower the platform;
If the operation direction of the control lever is horizontally forward or backward, it will move forward or backward with respect to the reference axis of the work platform, and if the operation direction of the control lever is horizontally right or left, it will move relative to the reference axis of the work platform. and an arithmetic device that calculates a control signal as instructed by the control lever to each control section of the electromagnetic control valve when an operation signal for moving the control valve to the right or left is input. An operation control device for an aerial work vehicle, which is characterized by:
