To suppress the damage and progress of the damage of a derricking member caused by deformation due to at least either of deflection in a lateral direction of the derricking member and twisting of the derricking member.SOLUTION: A derricking member deformation detection device 50 includes a detection unit 60 and a controller 80. The detection unit 60 detects deformation of at least either the deflection in the lateral direction (Y) of a derricking member (D) or the twisting of the derricking member (D). The controller 80 performs at least either of the restriction control for restricting the movement of a crane (1) and the warning control for emitting the warning to an operator of the crane (1) based on a detection value of the detection unit 60.SELECTED DRAWING: Figure 2

    【課題】起伏部材の横方向のたわみ、および起伏部材のねじれの少なくともいずれかの変形による、起伏部材の破損、および破損の進行を抑制する。【解決手段】起伏部材変形検出装置50は、検出部60と、コントローラ80と、を備える。検出部60は、起伏部材(D)の横方向(Y)のたわみ、および起伏部材(D)のねじれ、の少なくともいずれかの変形を検出する。コントローラ80は、クレーン(1)の作動を制限する制限制御、および、クレーン(1)の操作者に警告を発する警告制御、の少なくともいずれかの制御を、検出部60の検出値に基づいて行う。【選択図】図2
