To provide a battery driven electric hoist capable of suppressing generation of a situation where recovery of an object becomes difficult during lifting of the object by a traction member.SOLUTION: A battery driven electric hoist 1 is provided with: a drive control unit 10 that controls driving of an electric motor 2; a battery residual amount detection unit 11 that detects the storage residual amount of a battery B; a motor driving direction detection unit 13 that detects the rotary driving direction of the electric motor 2; and a delivery amount detection unit 12 that detects the delivery amount of a traction member L from a rotor 4. The drive control unit 10 limits the driving of the electric motor 2 when the storage residual amount of the battery B is detected to be equal to or lower than a prescribed threshold value on the basis of detection information from the battery residual amount detection unit 11, and changes the threshold value on the basis of detection information from the motor driving direction detection unit 13 and/or detection information from the delivery amount detection unit 12.SELECTED DRAWING: Figure 2

    【課題】牽引部材による対象物の昇降途中で対象物の回収が困難となる状況の発生を最小限に抑えることができるバッテリ駆動式電動巻き上げ機を提供する。【解決手段】本発明のバッテリ駆動式電動巻き上げ機1は、電動モータ2の駆動を制御する駆動制御部10と、バッテリBの蓄電残量を検出するためのバッテリ残量検出部11と、電動モータ2の回転駆動方向を検出するモータ駆動方向検出部13と、回転体4からの牽引部材Lの繰り出し量を検出するための繰り出し量検出部12とを備え、駆動制御部10は、バッテリ残量検出部11からの検出情報によってバッテリBの蓄電残量が所定の閾値以下であることが検出されると、電動モータ2の駆動を制限するとともに、モータ駆動方向検出部13からの検出情報及び/又は繰り出し量検出部12からの検出情報に基づいて閾値を変更する。【選択図】 図2
