A B S T R A C T Anchor element for the tilt-up and transport of pre- fabricated building components, particularly prefabricated wall panels, in cooperation with a hoisting shackle of the type having a torus-shaped body and a retractable arcuate locking bolt engaging a bolt hole in the exposed end portion of the anchor element, the latter defining a bridge portion between its bolt hole and its outer extremity and, as part of the bridge portion, one or two integral longitudinal ex- tensions of the anchor element which reach beyond the bridge portion and have two oppositely oriented force-transmitting surfaces one of which engages a surface of the hoisting shackle body during tilt-up, thereby preventing pivoting of the shackle body against the concrete recess which surrounds the exposed portion of the anchor element. The anchor ele- ment with two laterally spaced integral extensions engages the sides of the shackle body, and the anchor element with a central integral extension engages an aperture in the shackle body.
