To provide a lever hoist that allows for manipulation of an operating lever even if a power transmission mechanism is provided to transmit drive power from external drive means.SOLUTION: A lever hoist comprises an operating lever 50 that is manually rotated, a load sheave 33 that is rotated by the power from the operating lever 50, a pair of frames 31 and 32 that rotatably support the load sheave 33, a drive shaft 35 that transmits the driving force from the operating lever 50 to the load sheave 33, and a quick-turning grip 70 to be used to fast-forward a chain C1 that is passed around the load sheave 33 and also to quickly rotate the load sheave 33 located at one end of the drive shaft 35. Also included is a power transmission mechanism 100 comprising a sliding joint 170 and a shaft joint 180 that are connected to the other end of the drive shaft 35, and a deceleration mechanism that outputs the driving force from an external electric driver 300 in a decelerated state to the sliding joint 170 and the shaft joint 180.SELECTED DRAWING: Figure 6

    【課題】外部の駆動手段からの駆動力を伝達する動力伝達機構が設けられていても、操作レバーの操作を行うことが可能なレバーホイストを提供する。【解決手段】手動により回転操作させる操作レバー50と、操作レバー50からの動力で回転するロードシーブ33と、該ロードシーブ33を回転自在に支持する一対のフレーム31,32と、ロードシーブ33に対して操作レバー50からの駆動力を伝達する駆動軸35と、ロードシーブ33に掛け回されたチェーンC1を早送りすると共に、駆動軸35の一方側の端部に配置されたロードシーブ33を早回しするための早回しニギリ70と、を備え、駆動軸35の他方側の端部に連結される摺動継手170および軸継手180、および外部の電動ドライバー300からの駆動力を減速した状態で摺動継手170および軸継手180に出力する減速機構を備える動力伝達機構100を設けている。【選択図】図6
