Image Number 2 for United States Patent #6062620.

An apparatus for latching to any selected one of a family of electrical switching apparatuses having differently located centers of gravity includes a lifting bracket having a plurality of lifting attachment points whereby a crane or other hoisting device may be attached thereto. The lifting bracket with lifting attachment points enables the selected electrical switching apparatus to be lifted while being maintained generally level without excess tilting thereof. The apparatus also includes first and second latches movably connected to opposing ends of the apparatus for securely latching to the electrical switching apparatus being lifted. The lifting bracket of the apparatus also includes a locking flange for engaging the electrical switching apparatus during lifting and securely locking the first and second latches to the electrical switching apparatus.
