The present invention comprises: a load cell installed in a boom and sensing the weight of a mass lifted by a hook member connected by a wire rope; a weight correction unit correcting the weight of the mass measured through the load cell to generate a weight correction value; and an overload sensing unit sensing whether or not there is an overload based on the weight correction value corrected in the weight correction unit.

    본 발명은 상기 붐에 설치되며 와이어로프에 의해 연결된 후크부재에 의해 인양되는 중량물의 중량물 무게를 센싱하는 로드셀; 상기 로드셀을 통해 측정되는 중량물 무게를 보정하여 무게 보정값을 생성하는 무게 보정부; 및 상기 무게 보정부에서 보정된 무게 보정값을 기준으로 과부하 여부를 감지하는 과부하 감지부;를 포함할 수 있다.
