  • Patent number: 10486948
    Abstract: A rope hoist includes a rope drum mechanism easy to attach to a frame structure and clarified positioning reference. The rope drum is rotatably supported by a first support part on one end side and a second support part on another end side of the rope drum. A pair of supporting ribs having clearances with respect to a first drum support frame is provided with the first support part. A first connection member penetrates the supporting ribs and the first drum support frame in a state of both-end support. A second connection member penetrates a frame attachment portion and a second drum support frame in a state of cantilever. A support shaft couples the first support part and the second support part and is arranged on an axis passing through a position different from positions of the first connection member and the second connection member.
