To provide a crane display device which enables easy understanding of a relationship between a working radius and a critical load.SOLUTION: This crane display device comprises a control unit 15 that can cause a display unit 11 to display a first scale (radial scale 105) serving as a reference indicating a work radius, a second scale (weight scale 104) serving as a reference indicating the weight of a suspended load, a first pointer (radius pointer 107) indicating the work radius by pointing the first scale, and a second pointer (weight pointer 106) indicating the weight of the suspended load by pointing the second scale. The control unit 15 causes the first scale to be displayed along a linearly extending main axis with a value increasing toward one side in the main axis direction, the second scale to be displayed along the main axis with a value increasing toward the other side in the main axis direction, and the first and second scales to be displayed at positions corresponding to each other such that the second pointer indicates the critical load of the suspended load when the first and second pointers point the same positions.SELECTED DRAWING: Figure 3

    【課題】作業半径と限界荷重の関係を容易に把握することができるクレーンの表示装置を提供する。【解決手段】作業半径を示す基準となる第一目盛(半径目盛105)、吊り荷の荷重を示す基準となる第二目盛(荷重目盛104)、第一目盛を指し示すことで作業半径を示す第一指針(半径指針107)、並びに、第二目盛を指し示すことで吊り荷の荷重を示す第二指針(荷重指針106)を、表示部11に表示させることが可能な制御部15を具備し、制御部15は、第一目盛を、直線的に延びる主軸に沿うように、かつ、主軸方向一側に向かって値が増加するように表示させ、第二目盛を、主軸に沿うように、かつ、主軸方向他側に向かって値が増加するように表示させ、第一指針と第二指針が同じ位置を指し示した際に、第二指針が前記吊り荷の限界荷重を示すように、第一目盛と第二目盛を互いに対応付けた位置に表示させる。【選択図】図3
