Provided is a hoisting implement with which a vibration prevention effect in the short side direction of the hoisting implement can be improved without increasing the size of a trolley. In this hoisting implement 1 in which are installed at least four lower sheaves Sa (Sa1, Sa2, Sa3, Sa4) each formed in an approximately rectangular shape having a pair of long sides and a pair of short sides as seen in a plan view, the lower sheaves Sa (Sa1, Sa2, Sa3, Sa4) are disposed in a state in which the axial directions of each of the lower sheaves Sa (Sa1, Sa2, Sa3, Sa4) in a plan view are between a short-side direction x that is the extension direction of the short sides and a long-side direction y that is the extension direction of the long sides.

    L'invention fournit un accessoire de levage qui permet d'améliorer un effet anti-vibration dans sa direction côté court sans augmentation de la taille d'un chariot. Plus précisément, l'invention concerne un accessoire de levage (1) qui prend une forme sensiblement rectangulaire présentant selon une vue en plan une paire de côtés courts et une paire de côtés longs, et dans lequel sont montées au moins quatre roues à gorge inférieures (Sa (Sa1, Sa2, Sa3, Sa4)). Les roues à gorge inférieures (Sa (Sa1, Sa2, Sa3, Sa4)) sont disposées dans un état dans lequel leur direction axiale selon une vue en plan, se trouve entre une direction (x) côté court consistant en la direction de prolongement du côté court et une direction (y) côté long consistant en la direction de prolongement du côté long.

    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。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。
