To visualize, on a monitor screen, the state of a rated total load varied from one turning position to another of a crane boom so as to enabler easy understanding at a glance according to the overhang state (overhang length and overhang angle) of an outrigger in a mobile crane.SOLUTION: In a mobile crane 1, on a monitor screen 100 of a display device 46, a bracelet 150 divided into a plurality of segments 151-162 in a circumferential direction is displayed, and the state of a rated total load at the respective turning positions of a crane boom 4 is displayed by the segments 151-162. A revolving superstructure 170 turning corresponding to the crane boom 4 is displayed on the bracelet 150. The revolving superstructure 170 is turned to the position of the segment corresponding to the turning position of the crane boom 4, and displayed in the same display form as that of the segment.SELECTED DRAWING: Figure 8

    【課題】移動式クレーンにおいて、アウトリガの張出状態(張出長さおよび張出角度)に応じて、クレーンブームの旋回位置毎に変わる定格総荷重の状態を、一瞥して簡単に把握できるようにモニタ画面上に可視化すること。【解決手段】移動式クレーン1では、表示装置46のモニタ画面100に、円周方向に複数のセグメント151~162に分割された輪帯150を表示し、各セグメント151~162によりクレーンブーム4の各旋回位置における定格総荷重の状態を表示する。また、クレーンブーム4に対応して旋回する旋回体170を輪帯150上に表示し、旋回体170を、クレーンブーム4の旋回位置に対応するセグメントの位置に旋回させ、当該セグメントと同一の表示形態で表示させる。【選択図】図8
