ABSTRACT:
A lifting frame assembly having first and second spaced hooking members adjustably carried on a second portion of the lifting frame assembly is connectable to work tools of different sizes. The lifting frame assembly is connected to a lifting device by a lever arm which causes the lifting frame assembly to hang at an acute angle relative to a vertical plane so that the work tool may be aligned relative to a tool holder of a machine tool without interference. A first end portion of the lifting frame assembly is extensible in order to traverse the length of a ram of the machine tool and further improve alignment capabilities with the tool holder.
