<P>PROBLEM TO BE SOLVED: To provide an RFID tag with a load sensor having an inexpensive and small-sized constitution, capable of confirming the stage of a load applied to a crane immediately from a separated place, and heightening safety and efficiency of a working environment. <P>SOLUTION: This RFID tag 10 is equipped with the load sensor 11 for detecting the magnitude of a load, a light emitting part 12 wherein the emission state is changed by a signal from the load sensor 11, and a power source part 15 for supplying the power to the load sensor 11 and the light emitting part 12. The load applied to the crane can be confirmed with the inexpensive and small-sized constitution by the RFID tag 10 immediately from a separated place, to thereby heighten safety and efficiency of the working environment. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
