ABSTRACT:
Anchor element for the tilt-up and transport of prefabricated 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 extensions 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 element 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.
