To provide a lifting device of a concrete product suitable for a system of lifting longitudinal both end parts of a concrete product, that is capable of lifting and rotating a concrete product with a simple structure without being mounted with hardware and the like for lifting the concrete product and flexibly coping with different sizes of concrete products without requiring any special device.SOLUTION: A lifting device for a concrete product includes a center horizontal member 1 with a length dimension longer than a length dimension of the concrete product and L-shaped members 2 arranged on both sides of the center horizontal member 1. The L-shaped member 2 includes a horizontal member 3 and a vertical member 4. The horizontal member 3 has a through hole for slidably engaging with the center horizontal member 1. The vertical member 4 has a convex insertion fitting 10 that can be inserted in a recessed part of the concrete product on its lower part. The insertion fittings 10 are arranged on both sides of the vertical member 4 along a longitudinal direction of the center horizontal member 1.SELECTED DRAWING: Figure 1
【課題】コンクリート製品の長手方向の両端部を吊り上げる方式に適したものであって、コンクリート製品に吊り上げのための金物等を装着することなく、簡単な構成で吊り上げ及び回転が可能であるとともに、コンクリート製品のサイズが異なる場合にも特別な装置を要することなく、柔軟に対応できるコンクリート製品の吊り上げ装置を提供する。【解決手段】コンクリート製品の長さ寸法以上の長さ寸法を有する中央横架材1と、前記中央横架材1の両側に配設されるL字状架材2とを備え、前記L字状架材2は、横架材3と縦架材4とから形成され、前記横架材3は、前記中央横架材1にスライド可能に嵌合するための貫通孔を有し、前記縦架材4は、その下部にコンクリート製品の凹部に挿入可能な凸状の差込金具10を有し、前記差込金具10は、前記中央横架材1の長手方向に沿うように前記縦架材4の両側に配設されることを特徴とする。【選択図】図1
