To provide an electric hoist allowing easily determining brake lining wear.SOLUTION: Wear detection members 54 are installed between a brake wheel 43 of an electromagnetic brake mechanism 33 and a brake lining 44, and at the predetermined depth position when viewed from a surface on a side contacting with the brake disc 45 of the brake lining 44. When the brake lining 44 wears to the predetermined depth position due to contacting with the brake disc 45, the wear detection members 54 allow the wear of the brake lining 44 to be recognized so as to allow the wear of the brake lining 44 to be easily determined.SELECTED DRAWING: Figure 7

    【課題】ブレーキライニングの摩耗を容易に判別することができる電動巻上装置を提供する。【解決手段】電磁ブレーキ機構33のブレーキホイール43とブレーキライニング44の間に、ブレーキライニング44のブレーキディスク45と接触する側の表面から見て、所定の深さ位置に摩耗検知部材55を取り付けた。ブレーキディスク45との接触でブレーキライニング44が所定深さ位置まで摩耗すると、摩耗検知部材55によってブレーキライニング44の摩耗を認識できるので、ブレーキライニング44の摩耗を容易に判別することができる。【選択図】図7
