To measure the position of a suspended load more easily than before.SOLUTION: A crane 1 includes means for acquiring distances r1 to r3 to a suspended load H and a control unit 38. The control unit 38 calculates the position of the suspended load H based on acquired information about the distances r1 to r3. The means for acquiring the distances r1 to r3 includes a millimeter wave radar. Accordingly, the position of the suspended load H can be calculated only by acquiring the information about the distances r1 to r3 to the suspended load H. In addition, the position of the suspended load H can be suitably measured by using a low-cost millimeter wave radar with high distance measurement accuracy.SELECTED DRAWING: Figure 5
【課題】従来に比べて簡便に吊荷の位置を計測する。【解決手段】クレーン1は、吊荷Hまでの距離r1~r3を取得する手段と、制御部38とを備える。制御部38は、取得された距離r1~r3の情報に基づいて、吊荷Hの位置を算出する。距離r1~r3を取得する手段は、ミリ波レーダーを含んでいる。これにより、吊荷Hまでの距離r1~r3の情報を取得するだけで、吊荷Hの位置を算出することができる。また、距離計測精度が高く、かつ低コストのミリ波レーダーを用いて、好適に吊荷Hの位置を計測できる。【選択図】図5
