<p>The tackle is for handling prefabricated concrete components, in which anchor bolts have been cast, having heads behind which protrusions engage on lifting tackle equipped with a lifting eye. The protrusions engaging behind the bolt head consists of two or more claws on opposite sides, each on a stirrup tilting on a horizontal axis. Each stirrup has a further protrusion above and clear of the bolt head, under which lugs on a lifting device (13) with a crane hook eye (16) engage. The claws and the faces of the bolt with which they engage can be undercut. The stirrups can be accommodated in a housing, having supporting surfaces bearing against the housing wall to absorb transverse loads.</p> |
