ABSTRACT:
A coupler for hanging a prefabricated concrete body on a hoist. The connecting hook member has an arcuate slot and is provided on one end with an entrance opening for the slot, in which the connecting bolt head of an anchor bolt can be inserted. The connecting hook member is constucted as a hemispherically shaped component, on whose top side a hook pivot eye is attached, which is engaged pivotally with the suspension shackle in the shackle pivot eye. On the one side of the hook pivot eye the entrance opening formed as a mouth of the slot is positioned on the top side of the hemispherically shaped component. On the other side of the hook pivot eye the operating lever is positioned extending substantially radially. The hook pivot eye may be positioned in the plane of the slot. In this case the operating lever reaches a limit of its motion by contact with the bridging member of the suspension shackle. The hook pivot eye may however also be oriented perpendicularly to the slot.
