Technical Examples

An object handling device includes a support body, and an elongate anchor body mounted at the inner end thereof to the support body so as to project from the support body for insertion into an undercut cavity in an object to be handled. At least one anchor lug at or adjacent to the outer end of the anchor body is movable with the anchor body between a first position in which the anchor body is able to be inserted into or withdrawn from the cavity, and a second position in which the lug(s) engage respective undercut shoulder portions in the cavity. Means on the anchor body is engagable for moving the anchor body to move the anchor lug(s) between the first and second positions. Lift means on the support body is engagable by a crane to lift the object. Lock means is provided to block movement of the anchor lug(s) from the second position. In one aspect, the anchor body is rotatable to effect said movement of the anchor lug(s). In another, the lock means is slidable generally longitudinally of the anchor body means to a blocking position in which movement of the anchor lug(s) from the second position is blocked. In a further aspect, there is substantially no cavity or void in the object within a region outwards of said undercut shoulder portions sufficient to allow collapse or flow of the object material when the object is being lifted. Also disclosed is a form for defining an undercut cavity in a precast object.
