摘要： An lifting insert (106), particularly for embedment in the edges of thin concrete elements (11) is disclosed. The insert has a head (120) at one end which has a through aperture for the connection of a co-operating lifting link (1) and another end 121 for embedment within the concrete. The head of the insert has an interior region (150) bounded on each side by an exterior region (160) which extends to the longitudinal edges (124) of the insert. The exterior region is thicker than the interior region and the boundary (155) between the two regions defines an abutment surface (156). The thickness and width of the interior region is dimensioned to allow the lifting link (1) to be connected to the head (120) of the insert and the thickness of the outer region is dimensioned so as to restrict the rotation of the lifting link when a load is applied normal to the axis of the insert, and to effectively transfer the load by a couple developed across the full cross- section of the insert e.g. when tilting the concrete element from a horizontal position to a vertical position.
