Abstract

A body to be picked up is provided with a bolt having a relatively narrow shaft embedded in and projecting from the body and a relatively wide head on the shaft spaced from the body. This body is picked up by a device having a shackle provided with a crosspiece defining a lift eye to which is connected a grab cable and a pivot eye. A pickup member is pivotal on the pivot eye of the shackle about a pivot axis and has a generally radially extending actuation arm and an axially elongated and outwardly open pickup slot lying generally in a plane perpendicular to the axis and having a relatively wide end permitting radial passage of the head into and out of the slot and an angularly opposite relatively narrow end internally sufficiently wide to accommodate the head but externally insufficiently wide to permit radial passage of the head out of the slot. This slot is internally sufficiently wide between the ends to permit the head to pass angularly along the slot between the ends with the shaft extending out of the slot. Thus the member can pivot about the axis with the bolt engaged in the slot. An arcuate locking bolt may be displaceable in an arcuate guide slot in the pickup member to b…
