STORAGE STATE DETECTION DEVICE AND STORAGE STATE DETECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a storage state detection device capable of easily performing attachment/detachment in response to an object to be detected and maintaining detection accuracy of the storage state of a crane boom without exchanging a part. SOLUTION: The storage state detection device 1 is provided with a radio communication part 17 for informing of the storage state of the crane boom 3 by radio communication; a case body 11 incorporating the radio communication part 17; a clamp 12 for detachably fixing the case body 11 to a cylinder part 5 of a hydraulic cylinder 4 for driving the crane boom 3; and a limit switch 13 fixed to the case body 11 so as to switch the ON/OFF state by being in contact with the crane boom 3 when the crane boom 3 is stored. The radio communication part 17 detects the ON/OFF state of the limit switch 13 and transmits a signal according to the ON/OFF state. COPYRIGHT: (C)2008,JPO&INPIT
