PURPOSE: An anchor device for lifting a caisson using a gaff and a dangling iron hook and a method of lifting a caisson using the anchor device are provided to lift a caisson without separation of a dangling iron hook since the dangling iron hook is installed on a lifting wire through a fixed blade. CONSTITUTION: An anchor device for lifting a caisson comprises one or more gaffs(200) and one or more dangling iron hooks. The gaffs are buried at a caisson. A curved portion for connecting the dangling iron hook of the gaff is protruded to the outside of the caisson. The dangling iron hook is connected to the wire rope(111) of a marine crane and is coupled to the gaff. The dangling iron hook comprises a fixed blade(313) and a rotating blade(314). The fixed blade is coupled to the end of the wire rope. The curved gaff mount(311) of the fixed blade is coupled to the curved portion of the gaff.
