A novel lifting adaptor is described for lifting an elongate load having a pair of lifting brackets attached thereto, which comprises a beam having a connector at one end for attaching a hoist, a narrow tongue at the other end for insertion into one of the lifting brackets, and a lifting hook attached to the beam intermediate the tongue and connector for engaging the other lifting bracket, the tongue disposed obliquely to the remainder of the beam and in substantial alignment with the lifting hook so that both lifting brackets are engaged simultaneously, the beam sized to define a lifting point above the center of gravity of the load.
