Method of handling a structure and equipment of handling the same

A method of handling a structure, the method comprising the steps of:

• lifting up a reactor pressure vessel installed inside a building at a position outside said building up to a level above said building using a lifting device of a lifting machine which has the lifting device and moves on a beam, said beam crossing over said building inside of which said reactor pressure vessel is installed;
• moving said lifting machine on said beam, and moving said reactor pressure vessel until said reactor pressure vessel is positioned above an opening portion provided in a roof of said building;
• and
• lifting down said reactor pressure vessel to an installation position of said reactor pressure vessel in said building using said lifting device.

An equipment of handling a structure comprising:

• a plurality of columns arranged around a reactor building, said reactor building containing a reactor pressure vessel, and having an opening portion above said reactor pressure vessel;
• a beam crossing above said reactor building, both ends of said beam being connected to said columns;
• and
• a lifting machine having a lifting device, said lifting machine being movable on said beam.

A method of handling a structure, the method comprising the steps of:

• setting a beam outside a building inside of which a reactor pressure vessel is installed, said beam passing above said reactor pressure vessel and crossing over said building;
• setting a lifting machine having a lifting device for lifting said reactor pressure vessel onto said beam, said lifting machine being moved on said beam;
• carrying in a shield for shielding radioactive rays radiated from said reactor pressure vessel into said building through an opening portion provided in a roof of said building;
• carrying out said reactor pressure vessel together with said shield upward from said building using said lifting device;
• moving said lifting machine on said beam until a position where said building does not exist below said reactor pressure vessel;
• then lowering said lifting machine hanging said reactor pressure vessel down to the ground using a jack type hoisting device arranged adjacent to said building;
• moving said lifting device on a transporting rail installed in the ground until a bottom portion of said reactor pressure vessel comes to a storage building for said reactor pressure vessel;
• and
• lifting down said reactor pressure vessel into said storage building using said lifting device provided in said lifting machine.
