The present invention is a means for detecting the boom length according to the expansion and contraction of a working device (boom, boom) of a crane. That is, the present invention relates to a boom length detection sensor (boom length sensor), which is an accessory of the crane overload prevention system. Boom breakage and equipment overturn may occur due to excessive withdrawal of the boom out of a safe working range, or an increase in the moment of the boom due to an overload of the working device. Here, by limiting the maximum working range of the crane, the boom length detection sensor automatically limits the safe working range to prevent the life and property damage of workers due to the overturning of the equipment in advance.

    본 발명은 크레인의 작업장치(붐, boom)의 신축에 따른 붐 길이를 검출하는 수단, 즉 붐이 안전한 작업범위를 벗어나서 과도하게 인출되거나, 작업장치(다단붐)에 과하중으로 인한 붐의 모멘트 증가로 붐 파손 및 장비 전복이 발생하는데, 이때 크레인의 최대 작업범위를 제한하여 장비 전복에 따른 작업자의 생명 및 물적피해를 미연에 방지할 수 있도록 안전한 작업범위를 자동으로 제한하는 기능을 수행하는 크레인 과부하방지 시스템의 부속물인 붐 길이 검출센서(붐길이센서)에 관한 것이다.
