ABSTRACT Lifting tackle comprises a hook sheave suspended from a pulley block sheave supported between a pair of parallel arms, the free ends of which are bent to form one member of a pair of gripping jaws the other member being of L shaped pivoted between the two parallel arms. The L shape member of the jaws engages the upper surface of a flange of a girder or beam and the weight of the hook sheave and load bring the jaw integral with the parallel arms into engagement with the under surface of the flange so that the flange is gripped firmly between the jaw. This lifting tackle may be attached to the upper or lower flange of the grider or beam and will raise a load into substantial engagement with the underside of the girder or beam.
