[0004] When hoisting, the flipping device for vertically stacked precast concrete wall panels of the above-mentioned patent needs to place a hard pad, and the precast concrete wall panels that have been transported to the construction site and stacked vertically are hoisted onto the flipping device, and the precast concrete wall panels are positioned in the middle of the horizontal base as much as possible. The hard pads and gaskets are clamped to the surface of the precast concrete wall panels through fixing bolts, and after checking that they are correct, the hooks on the precast concrete wall panels are released, and the hooks are installed on the side of the precast concrete wall panels. The hooks are slowly pulled to flip 90° toward the side of the steel baffle. However, the device requires the use of a crane and heavy machinery, and cannot complete the operation independently. Multiple people are required to work at the same time, and the use site is limited. Utility Model Content
