To provide a hanger in a short side direction of which anti-vibration effect can be improved without increasing a size of a trolley.SOLUTION: In a hanger 1 which is formed into a substantially rectangular shape with a pair of long sides and a pair of short sides in a plan view and in which at least four lower sheaves Sa (Sa1, Sa2, Sa3, Sa4) are installed, the lower sheaves Sa (Sa1, Sa2, Sa3, Sa4) are located in the state that in a plan view, an axial direction of the lower sheaves Sa (Sa1, Sa2, Sa3, Sa4) is between a short side direction x that is an extension direction of the short side and a long side direction y that is an extension direction of the long side.SELECTED DRAWING: Figure 1
【課題】トロリを大型化することなく吊具の短辺方向における振止効果を向上できる吊具を提供する。【解決手段】平面視で一対の長辺と一対の短辺とを有する略長方形に形成されていて少なくとも四つの下方シーブSa(Sa1、Sa2、Sa3、Sa4)を設置される吊具1において、平面視で下方シーブSa(Sa1、Sa2、Sa3、Sa4)の軸方向が短辺の延長方向である短辺方向xと長辺の延長方向である長辺方向yとの間となる状態で下方シーブSa(Sa1、Sa2、Sa3、Sa4)を配置する。【選択図】図1
