PROBLEM TO BE SOLVED: To enable continual use of an existing weight frame and eliminate work time necessary for replacement by increasing the strength of a weight frame itself without replacing the existing weight frame.SOLUTION: A balance weight 1 includes a weight frame 7, and a laminated weight 9 stacked in the weight frame 7, and is vertically moved along guide rails 17L and 17R following the movement of an elevator car. The weight frame 7 includes a pair of left and right vertical columns 9L and 9R having U-shaped horizontal sections, an upper beam 11 for connecting the vertical columns upward, and a lower beam 13 for connecting the vertical columns downward, and reinforcing members 24 are fitted to the vertical columns 9L and 9R along a vertical direction.SELECTED DRAWING: Figure 1

    【課題】既設の重り枠を交換することなく、重り枠自体の強度を上げることで、既設重り枠の使用を継続でき、交換に要する作業時間を無くす。【解決手段】重り枠7と、この重り枠7内に積層される積層重り9とを備え、乗りかごの移動に伴いガイドレール17L,17Rに沿って上下動するつり合い重り1において、重り枠7は、水平断面がコ字状に形成された左右一対の縦柱9L,9Rと、縦柱同士を上方で連結する上梁11と、縦柱同士を下方で連結する下梁13とを具備し、縦柱9L,9Rには、垂直方向に沿って補強部材24が取り付けられている。【選択図】図1
