[0020]

As shown and described above, the method of lifting a car unit of an elevator for a unit housing according to the present invention uses a plurality of guide rails temporarily fixed to both sides of a car at a required interval in the horizontal direction. A hanging jig having an arm member having a hanging hole formed therein is fixed, a hanging hole at a required position is selected from the plurality of hanging holes, and hanging wires are hung on the hanging hole,
Since the car is lifted so as to be substantially vertical, even if the center of gravity of the car unit is deviated due to the attachment of various devices or parts, the center of gravity of the car unit is used as a hanging hole for hanging wires. An optimum position can be selected according to the position, and the car unit can be lifted vertically. In addition, even if the position of the center of gravity differs for each car unit of the elevator, the adjustment can be performed quickly, so that the work can be efficiently and safely performed when the car is carried into the space of the narrow residential unit. Furthermore, since the guide rail to which the hanging jig is fixed is very robust used for vertically moving the elevator, the fixing of the hanging jig and the lifting of the car can be performed stably and safely. it can. In addition, since the suspension is lifted by the suspension jig using the guide rail, only the suspension jig needs to be manufactured, and there is no need to change the design of the elevator or add components.

Further, the hanging jig of the present invention can not only lift the car unit vertically but also fix the reinforcing member and the arm member even when the center of gravity of the car unit of the elevator is deviated as described above. Since the members form a triangle, the car unit of the elevator can be stably and safely lifted with extremely high strength. Moreover, the structure is simple and economical.
