全装置。 In a work machine having a boom such as an aerial work vehicle, a boom operation detector that detects the operation of the boom;
The control lever detector detects the operation or amount of operation of the control lever that controls boom operation, and the signals output from the boom operation detector and control lever detector are compared to determine whether the boom operation detector is operating. Alternatively, a safety device for a detector characterized in that it is equipped with a comparison judgment circuit that compares and judges whether the detection signal from the boom operation detector deviates from the allowable range value of the amount of change due to actual boom operation. .
