<P>PROBLEM TO BE SOLVED: To provide a lifting device capable of reliably lifting a cobblestone having an irregular shape and efficiently conveying it, and to provide a construction method by which it is finished in a short construction period. <P>SOLUTION: Holding piece parts 14a, 14b at a distal end side of a pair of turnably connected support pieces 11a, 11b have a substantially cross-sectional recessed shape, and are disposed opposite each other so as to be attached. When a cobblestone is fitted into a space between the holding piece parts 14a, 14b, held between the respective claw parts 142a, 142b positioned at both side of the holding piece parts 14a, 14b, and lifted, the cobblestone is supported by at least three distal ends of the claw parts 142a, 14b so as to be lifted. Even when the cobblestone has an irregular shape, it is reliably supported and conveyed by being held therebetween, and is efficiently and reliably conveyed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
