PROBLEM TO BE SOLVED: To provide a method of improving a balance weight device of an elevator which makes it possible to enhance strength of the balance weight device in a short time and which can reduce the quantity of waste.SOLUTION: A method of improving the balance weight device 10 of an elevator comprises a step of removal which removes an existing upper beam of a weight body frame 20 from an existing vertical beam 50, a step of processing which processes a retrofitting mounting hole 61 on the existing vertical beam 50 and a step of attachment which attaches a retrofitting upper beam 41 to the existing vertical beam 50 of the weight body frame 20. In the step of attachment, the retrofitting upper beam 41 is attached to the existing vertical beam 50 by a fastening member 70 inserted into the retrofitting mounting hole 61 and in the step of processing, the retrofitting mounting hole 61 is formed on a downward direction of an existing attachment hole 60 for attaching the existing upper beam on the existing vertical beam 50.SELECTED DRAWING: Figure 3
【課題】短時間で釣合錘装置の強度を高めることが可能にして、廃棄品の量が低減されたエレベータの釣合錘装置の改造方法を提供すること【解決手段】エレベータの釣合錘装置10の改造方法は、錘本体枠20の既存上梁を、既存縦梁50から取り外す取外工程と、既存縦梁50に改造取付孔61を加工する加工工程と、錘本体枠20の既存縦梁50に、改造上梁41を取り付ける取付工程と、を備えている。取付工程において、改造上梁41は、改造取付孔61に挿入された締結部材70によって既存縦梁50に取り付けられ、加工工程において、改造取付孔61は、既存上梁を既存縦梁50に取り付けるための既存取付孔60の下方に形成される。【選択図】図3
