To provide a crane device capable of automatically specifying the winding number of a wire before performing crane work.SOLUTION: A boom is brought down only by a first predetermined angle by a controller (S21 to S24). A wire is loosened by the length corresponding to the first predetermined angle. The loosening amount of the wire depends on the winding number of the wire. The controller winds up the loosened wire and acquires total output pulse number showing the length of the wound wire. A memory stores a correspondence table in which the total output pulse number and the wire winding number are associated with each other in advance. The controller specifies the winding number of the wire associated with the acquired total output pulse number as the present winding number of the wire and makes the memory store the specified winding number of the wire.SELECTED DRAWING: Figure 6

    【課題】クレーン作業を行う前にワイヤ掛数を自動で特定することができるクレーン装置を提供する。【解決手段】コントローラは、ブームを第1所定角度だけ倒伏させる(S21~S24)。第1所定角度に応じた長さだけワイヤが弛む。ワイヤの弛み量は、ワイヤ掛数に依存する。コントローラは、弛んだワイヤを巻き上げ、巻き上げたワイヤの長さを示す総出力パルス数を取得する。メモリは、総出力パルス数とワイヤ掛数とを対応付けた対応テーブルを予め記憶する。コントローラは、取得した総出力パルス数と対応付けられたワイヤ掛数を現在のワイヤ掛数として特定し、特定したワイヤ掛数をメモリに記憶させる。【選択図】図6
