るホイストのリミツト装置。[Scope of Claim for Utility Model Registration] In a hoist in which a rotating drum around which a hanging rope is wound is rotated via a reduction gear mechanism interlocked with the rotating main shaft of an electric motor, one gear of the reduction gear mechanism described above. A main shaft of a screw for moving a striker that rotates in engagement with the main shaft for moving a striker is pivotally installed, and the striker, which is screwed into a part of the feed screw of the main shaft for moving a striker, can be freely slid by a rotation prevention guide. A limit device for a hoist, characterized in that the striker is guided in a non-rotatable manner, and a limit switch is disposed at a predetermined position within the movement range of the striker.
