<p>A lifting device has a winding mechanism (13) and a platform (3). The winding mechanism (13) takes up at least two wires (14) paid out in a loop. The platform (3) is suspended by looped portions (21A, 21B) of the at least two wires (14) paid out from the winding mechanism (13) and has at least four wire guiding rotating bodies (22A, 22B) over which the looped portions (21A, 21B) of the wires (14) are passed. In the platform (3), the looped portion (21A) of one of the wires (14) is passed over the at least two wire guiding rotating bodies (22A) and the looped portion (21B) of the other wire (14) is passed over the at least two wire guiding rotating bodies (22B).</p> |
