Prefabricated concrete component handling tackle - has connector with central bore for suspension link through which arm swings

摘要

The handling tackle suspends a prefabricated concrete component from a crane, comprising an anchor bolt grouted into the component, with shank and coupling head, and a spherical connector for attachment to the head, and from which a manipulating arm protrudes. The connector has a circular slot extending through roughly 180 deg. and accommodating the head, with an insertion opening for the latter at one end, the shank working in the slot. In the connector is a central bore (10) for a chain link, running at right angles to the plane of the slot (7) and through the centre of the curve. A suspension link (12) is accommodated in the bore, and the manipulating arm (6) is used to position the insertion opening (8) for the slot. It can be swung through the link.
