PROBLEM TO BE SOLVED: To provide a method for preventing a wire rope in a main winding device in a calcined ore conveying crane facility from being loosened.SOLUTION: A method for preventing a wire rope in a calcined ore conveying crane facility for conveying a container loaded with calcined ores from being loosened, when an empty container suspended by the wire rope is descended, comprises the steps of: measuring, by a pin type load meter disposed in an end part of the wire rope 13 wound up or down by a main winding device 11, a weight of an empty container 3E suspended by the wire rope 13; comparing the measured weight value of the empty container 3E with a preset weight value to detect presence or absence of abnormality halfway winding down; and upon detection of the abnormality, stopping winding down operation of the main winding device 11.SELECTED DRAWING: Figure 3
【課題】焼鉱搬送クレーン設備における主巻装置のワイヤロープの弛みの発生を防ぐ方法を提供する。【解決手段】本発明は、焼鉱を装入したコンテナを搬送する焼鉱搬送クレーン設備において、ワイヤロープに吊り下げた空のコンテナを降下させる際のそのワイヤロープの弛みを防止する方法であって、主巻装置11により巻き上げ又は巻き下げられるワイヤロープ13のエンド部に設けたピン型荷重計により、ワイヤロープ13に吊り下げられた空のコンテナ3Eの重量を測定し、その空のコンテナ3Eの測定重量値と、予め設定した重量値とを比較することにより、巻き下げ途中の異常の有無を検出し、異常を検出した場合には、主巻装置11の巻き下げ動作を停止させる。【選択図】図3
