Abstract: A package or carton lifter includes tongs which have two laterally spaced pairs of jaw levers physically connected intermediately of the first and second ends. A pair of cross-members rigidly connects the lever pairs at points below the lever-pivotal connections for pivotal movements in unison. First and second links pivotably connected to one another join the first ends of the levers of each pair for opening and closing the tongs, and a first handle extends between the connection points of the links. A second handle is substantially coextensive with the first handle and extends between the pivotal connections of the pairs of levers. Each of the cross-members has an inner side, and a gripping member is provided on the inner side of each of the cross-members for grasping a case or the like.
