Abstract
A rope hoist includes: a rope drum around which a wire rope W is wound; a support shaft and a limit switch bolt arranged to be parallel to the rope drum; limit switch mechanisms; and a rope guide mechanism moving in accordance with a winding state of the wire rope W, and making the limit switch mechanisms perform on/off operation. Each of the limit switch mechanisms includes: a limit switch metal fitting into which both of the support shaft and the limit switch bolt are inserted, in which the limit switch metal fitting is sandwiched and fixed by nuts from both sides thereof in an axial direction of the limit switch bolt.

A rope hoist, comprising:
- a rope drum around which a wire rope can be wound;
- end frame members respectively arranged at both ends of the rope drum, the rope drum being rotatably supported by the end frame members;
- a support shaft bridged between both of the end frame members, and arranged to be parallel to the rope drum;
- limit switch mechanisms arranged at a predetermined wind-up position and a predetermined unwind position, respectively, of the wire rope, the limit switch mechanisms each having a limit switch metal fitting;
- and
- a moving member moving in accordance with a winding state of the wire rope, and making the limit switch mechanisms perform on/off operation;
- the rope hoist comprising:
- a limit switch fixing bar arranged to be parallel to the support shaft and the rope drum;
- wherein both of the support shaft and the limit switch fixing bar are inserted into each of the limit switch metal fittings;
- and
- the limit switch metal fitting is fixed by a fixing means in a manner that a position of the limit switch metal fitting in an axial direction of the limit switch fixing bar can be adjusted.
