するクレーン装置に右けるブーム長の検出機構。The wire is paid out and wound up in accordance with the extension length of the telescoping boom, and the amount of wire paid out and taken up is converted into the amount of movement of the slider of the potentiometer via a transmission mechanism. In a boom length detection mechanism in a crane device that detects the extension length of a boom from a change in resistance, a non-detection potentiometer having a structure separate from the potentiometer is connected to the detection potentiometer so as to be interlocked with the detection potentiometer, By regulating the amount of slider movement in the detection potentiometer that corresponds to the maximum tension length of the boom with the maximum slider movement amount of the non-detection potentiometer itself, the non-detection potentiometer can limit the usage range of the detection potentiometer. A boom length detection mechanism for a crane device characterized by being variable.
