PROBLEM TO BE SOLVED: To provide a novel vertical frame replacement method and a novel vertical frame replacement tool of a balance weight without losing workability.SOLUTION: A vertical frame replacement method of a balance weight including a pair of left and right vertical frames, an upper beam for connecting the vertical frames on an upper side, a lower frame for connecting the vertical frames on a lower side, and a laminate weight stored in a space including the vertical frames, the upper beam and the lower beam includes the step (S1) of lowering the balance weight to the pit of a hoistway to come into contact with a buffer installed on the pit, the step (S3) of fitting a weight presser between a fitting plate provided on the upper beam and a fixing tool provided in the bottom surface of the balance weight, the step of releasing the connection of the upper beam, the lower beam, and the left and right vertical frames to remove the vertical frames, the step (S5) of connecting prepared replacement vertical frames to the upper beam and the lower beam, and the step (S9) of removing the weight presser.SELECTED DRAWING: Figure 3
【課題】作業性を損なうことなく新規なつり合い重りの縦枠交換方法及び縦枠交換用治具を提供すること。【解決手段】左右一対の縦枠と、縦枠同士を上側で連結する上梁と、縦枠同士を下側で連結する下枠と、縦枠、上梁及び下梁で構成される空間内に収納される積層重りとを備えたつり合い重りの縦枠交換方法であって、当該つり合い重りを昇降路のピットまで降下させ、ピットに設置されている緩衝器上に接触させる工程(S1)と、前記上梁に設けられた取付板と前記つり合い重りの底面に設けられた固定具との間に重り押さえを取り付ける工程(S3)と、前記上梁及び下梁と左右の前記縦枠との連結を解除して当該縦枠を取り除く工程と、用意された交換用の縦枠と前記上梁及び下梁とを連結する工程(S5)と、前記重り押さえを取り外す工程(S9)と、を備える。【選択図】図3
