SOLUTION: A horizontal hanging frame 4 is lifted by opening / closing links 2a, 2b which narrow the interval when the object 1 to be hung is lifted, and movable horizontal frames 5, 6 approached / separated from the horizontal hanging frame 4 by the opening / closing links 2a, 2b. To support. Horizontal hanging frame 4 or movable horizontal frame 5, 6 Are provided with cursors 7 and 8, the holding arms 9 and 10 are suspended, and the movable horizontal frames 5 and 6 are provided with a screw shaft 11 of a right-hand screw and a screw shaft 12 of a left-hand screw. The two screw shafts 11 and 12 are connected by a rotation transmission connection mechanism 13 that can transmit a rotational force and has play in the screw axis direction, and nut runners 14 and 15 screwed to the two screw shafts 7 and 8 are connected to the cursors 7 and 8. Link. When the lifted body 1 is lifted and the lock of the lock lever 3 is released, the holding arms 9 and 10 are chuck-moved within the play size of the rotation transmitting and connecting mechanism 13 in the axial direction. 9 and 30, the article to be lifted W can be chucked and lifted.
