PROBLEM TO BE SOLVED: To provide a hoisting tool capable of being easily detachably and rigidly locked without opening a tap hole to a die flange at the time of hoisting, or welding a hoisting ring. SOLUTION: This hoisting tool hoist a heavy object having a planar part such as a molding die for rubber, plastic moldings. The tool comprises a main spindle 2 equipped with a hoisting ring 7 at an upper end and a die lock board 4 at a bottom end; and a circular-sectioned guide pipe 3 turnably fitted with an upper side of the die lock board 4 of the main spindle 2 and decentered from the main spindle 2. The dimension of the die lock board 4 in a plane view is smaller than the dimension of the guide pipe 3 in a plane view. The main spindle 2 is rotated, to make the shape and the dimension to make a part of the die lock board 4 hang over the bottom face of the guide pipe 3. COPYRIGHT: (C)2006,JPO&NCIPI
