Claims

[Claims for Utility Model Registration] A lifting beam that is raised and lowered by winding and unwinding the main wire is disposed above a structure that can be raised and lowered, and one piece is pivotally supported by the lifting beam. Or, in a hanging/detachable device for a structure in which a plurality of hanging hooks can be attached/detached to a hook member provided with the above-mentioned structure, a switching member interlocked with the shaft support of the lifting hook of the above-mentioned lifting beam via a connecting rod or the like. is rotatably supported, and has a gear on the shaft provided on the switching member, and a weight on the upper end, and the lower end of the operating lever that maintains a tilted position at all times is fixed, and a stopper pin is attached to the outer periphery of each of the gears. Plant it, and furthermore,
The upper end of a connecting lever with a weight attached to the lower end of the shaft is rotatably supported, and a gear that meshes with the gear is pivotally supported in the middle of the connecting lever,
An automatic hanging/detaching device characterized in that one end of a messenger lever is connected to the gear, and the upper end of the other end of the messenger lever is connected to the main wire for lifting and lowering the lifting beam.
