To provide a crane display device which can easily grasp a relationship between a working radius and a critical load.SOLUTION: This device comprises a control part 15 which can display a first scale (radius scale 105) that serves as a reference for a working radius, a second scale (load scale 104) that serves as reference for a load of a lifting cargo, a first pointer (radius pointer 107) that indicates the working radius by pointing to the first scale, and a second pointer (load pointer 106) that indicates the load of the lifting cargo by pointing to the second scale, on a display part 11. The control part 15 displays the first scale and the second scale at positions associated with each other so that the second pointer indicates a limit load of the lifting cargo when the first pointer and the second pointer point to a same position.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)、前記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、前記第二目盛を指し示すことで前記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、前記制御部15は、前記第一指針と前記第二指針が同じ位置を指し示した際に、前記第二指針が前記吊り荷の限界荷重を示すように、前記第一目盛と前記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
