PROBLEM TO BE SOLVED: To provide a lifting auxiliary tool capable of maintaining the engaged state of an engaging part of a sling belt with a hanging ear of a transformer without causing friction between the engaging part of the sling belt and the hanging ear of the transformer during installing of the transformer on the upper part of an electric pole or during removing of the transformer from the upper part of the electric pole.SOLUTION: A lifting auxiliary tool 1 for preventing a sling belt 10 used for lifting a transformer 100A by a crane or the like from being released from a state in which it is engaged with and attached to a hanging ear 103 of the transformer 100A during installing of the transformer 100A on the upper part of an electric pole or during removing of the transformer 100A from the upper part of the electric pole, is provided with: a fixed part 2 that is formed by a magnet and fixed to a lid 102 of the transformer 100A; and arms 3a and 3b that are inserted into engaging parts 12a and 12b of the sling belt 10 and that lift the upper parts of the engaging parts 12a and 12b to maintain a state in which the lower parts of the engaging parts 12a and 12b are engaged with the hanging ear 103.SELECTED DRAWING: Figure 3
【課題】変圧器を電柱上部に設置する際、または変圧器を電柱上部から撤去する際に、スリングベルトの係合部と変圧器のつり耳との間に摩擦が生じることなく、スリングベルトの係合部が変圧器のつり耳に係合した状態を保持する吊上補助具を提供する。【解決手段】吊上補助具1は、変圧器100Aを電柱上部に設置する際、または変圧器100Aを電柱上部から撤去する際に、クレーン等で変圧器100Aを吊り上げるときに使用されるスリングベルト10が変圧器100Aのつり耳103に係合されて取り付けられた状態から外れることを防止する器具であり、磁石により形成されて変圧器100Aの蓋102に固定される固定部2と、スリングベルト10の係合部12a,12bに挿入され、係合部12a,12bの上部を持ち上げて係合部12a,12bの下部がつり耳103と係合している状態を保持するアーム部3a,3bとを備えている。【選択図】 図3
