Is done.

  As shown in FIG. 2, in the slinging work area P1, signals of the electronic tags 4A, 4B, 4G of the material 2A and slinging workers 3A, 3B are detected. Then, when the winding starts as shown in FIG. 3, only the tag signal of the material 2A is obtained, and the tag signals of the mounting workers 3C to 3F are detected when the material moves to the mounting work area P2 as shown in FIG. It has become. Then, as shown in FIG. 5, when the tag reader 6 together with the hook block 11 moves away from the attachment work area P2 after the attachment of the material 2A, all tag signals are not detected. Then, when the work is repeated, as shown in FIG. 2, the tag signals of the slinging workers 3A and 3B and the material 2A are detected when returning to the slinging work area P1 again. One cycle of heavy work is completed.

  That is, as shown in FIG. 2, in the slinging work area P1, the tag reader 6 provided in the hook block 11 is located within the communication range T because the electronic tag 4A held by the suspended material 2A is located within the communication range T.

At this time, since the hook block 11 is located near the ground, the electronic tags 4B and 4C carried by the two workers 3A and 3B who perform the slinging work around the material 2A are also within the communication range T of the tag reader 6. The tag reader 6 detects the detection data of the two electronic tags 4B and 4C. As shown in FIG. 1, the detected detection data is sent from the tag reader 6 to the transmission unit 7, and sent from the transmission unit 7 to the reception unit 8 in the operation room 13 via the communication antenna 5 at the jib tip 12 a. And stored in the data storage unit 9.

  Further, when the material 2A is rolled up from the slinging work area P1 toward the predetermined mounting work area P2, the electronic tags 4 of the slinging workers 3A and 3B are out of the communication range T of the tag reader 6, and as shown in FIG. Only the material 2 </ b> A suspended by the hook 11 a is positioned within the communication range T of the tag reader 6, and only this material information is detected and accumulated in the data storage unit 9.

Identification information of the electronic tags 4D to 4G held and carried is detected by the tag reader 6. The detected detection data is sent from the tag reader 6 to the transmission unit 7, sent from the transmission unit 7 to the reception unit 8 via the communication antenna 5, and accumulated in the data storage unit 9.

  Further, as shown in FIG. 5, after the attachment of the material 2A in the attachment work area P2 is completed, the empty hook 11a (hook block 11) is moved to the slinging work area P1. At this time, since the electronic tag 4 is not located within the communication range T of the tag reader 6, the tag reader 6 is not detected.

  Further, as shown in FIG. 1, in addition to the confirmation of the lifting work status by detecting the identification information of the electronic tag 4, in this embodiment, the work status below the hook part is photographed by the work monitoring camera 20. The video signal is also sent from the transmission unit 7 to the reception unit 8 in the operation room 13 via the communication antenna 5, and the video can be displayed on the monitor 22 in real time. Therefore, even if it is difficult for the operator of the crane 1 to check the work status, the crane 1 can be efficiently operated while checking the image on the monitor 22.

  Further, the detection data (identification information of the material 2 and the worker 3) accumulated in the data storage unit 9 becomes data associated with the position of the hook block 11 and time (time), and this is displayed on the monitor 22. By doing so, the crane operator can specify work contents such as slinging, hoisting, mounting, and lowering. That is, based on these detection data, it is possible to record as work performance data such as “who, when, what and what work”.
