Zusammenfassung: | A load lifting apparatus comprises a first housing, a second housing and a mechanical obstruction structure(s). The first housing is sized to slide over an upset tubular having a given diameter, wherein the first housing comprises the mechanical obstruction structure(s) that is designed to move radially inward when engaged with the second housing. The compressed internal diameter of the mechanical obstruction structure(s) can contact the upset tubular, wherein the upset tubular can then be supported by the mechanical obstruction structure(s) and the second housing, for safely lifting the upset tubular. |
