PROBLEM TO BE SOLVED: To provide a suspension reversal device which can safely and reliably reverse a plate-like member at a low cost.SOLUTION: A suspension reversal device includes: a main frame 4 suspended from a crane; a first wire 10 which hangs one end side of a PC floor slab 15 with an undersurface of the main frame 4; a second wire 11 which hangs the other end side of the PC floor slab 15; and a reversal winding machine 15 which can adjust a suspension length of the second wire 11. The first wire 10 and the second wire 11 are disposed on both sides of a center of gravity of the main frame 4. From the state such that the first wire 10 and the second wire 11 are so suspended as to cross each other and support both ends of the PC floor slab 15, the second wire 11 is wound down by the reversal winding machine 12 and the length thereof is elongated, and after the PC floor slab 15 is suspended from the first wire 10, the second wire 11 is wound up and the length thereof is shortened.
【課題】低コストで安全且つ確実に板状部材を反転できる吊り下げ反転装置を提供する。【解決手段】吊り下げ反転装置は、クレーンで吊り下げたメインフレーム4と、メインフレーム4の下面でPC床版15の一端側を吊り下げる第一ワイヤー10と、PC床版15の他端側を吊り下げる第二ワイヤー11と、第二ワイヤー11の吊り下げ長さを調整可能な反転巻き上げ機12とを備え、第一ワイヤー10と第二ワイヤー11はメインフレーム4の重心の両側に配置し、第一ワイヤー10と第二ワイヤー11を交差するように吊り下げてPC床版15の両端を支持した状態から、反転巻き上げ機12によって第二ワイヤー11を巻き下げて長さを延ばし、第一ワイヤー10によってPC床版15が垂下した後で第二ワイヤー11を巻き上げて長さを短くすることでPC床版15を反転させる。【選択図】図3
