To automatically or visually detect the abrasion of a wire rope groove on an electrically-driven hoist.SOLUTION: This electrically-driven hoist has: a drum 53 on which a wire rope 52 for suspending a load is wound; and a motor that lifts/lowers the load by rotating the drum 53 to vertically move the wire rope 52 wound on the drum 53. The drum 53 has a wire rope groove 1 through which the wire rope 52 passes, and a step 4 is formed in the groove bottom 2 of the wire rope groove 1.SELECTED DRAWING: Figure 3

    【課題】電動巻上機においてワイヤロープ溝の摩耗を目視で又は自動的に検知する。【解決手段】吊り荷を吊るためのワイヤロープ52が巻きつけられたドラム53と、ドラム53を回転させてドラム53に巻きつけられたワイヤロープ52を上下動させ吊り荷を上げ下げする電動機を有する電動巻上機であって、ドラム53はワイヤロープ52が通過するワイヤロープ溝1を有し、ワイヤロープ溝1の溝底部2には段差部4が形成されている。【選択図】図3
