の荷役作業車における自動揚高制御装置。[Scope of Claim for Utility Model Registration] (1) A lift height detector that continuously detects the lift height of the attachment of a cargo handling vehicle, and a device that automatically operates the attachment until the detected lift height of the lift height detector reaches the required target lift height. An automatic lifting height control device for a cargo handling vehicle that is equipped with a lifting control means that automatically raises or lowers the attachment and stops it, includes a lifting height confirmation detector that detects when the attachment has reached a predetermined lifting height confirmation position, and The lift height detected by the lift height detector when the lift height confirmation position is detected by the height confirmation detector is compared with the lift height at the lift height confirmation position, and the deviation between the two is determined to a predetermined tolerance value. An automatic lifting height control device for a cargo handling vehicle, which is equipped with a means for stopping automatic lifting height control when the height is exceeded. (2) The lever operation detector and lever operation detector detect whether the manual lift control lever has been operated in the ascending or descending direction. An automatic lifting height control device for a cargo handling vehicle as set forth in claim (1) of the utility model registration, which is provided with means for stopping automatic lifting height control when detected. (3) Automatic lifting height control is prohibited or canceled when the mast is detected to be in a forward leaning state by the mast forward leaning detector and the mast forward leaning detector for detecting the forward leaning state of the mast. An automatic lift height control device for a cargo handling vehicle as set forth in claim (1) of the utility model registration claim, which is provided with a means for controlling the lift height. (4) A detector for detecting that the attachment lifting drive pump is driven by the engine and that the engine rotational speed is lower than the maximum torque rotational speed, and this detector detects that the engine rotational speed is Utility model registration claim 1, which is provided with a means for prohibiting or stopping the raising operation of the attachment by automatic lifting height control when it is detected that the rotation speed is below the maximum torque. Automatic lifting height control device for cargo handling vehicles.
