ABSTRACT:
A lifting tool for batteries and the like includes first and second members each having an upright end leg provided with a gripping shoe. The leg of the first member merges into a horizontal handle, while the leg of the second member merges into a connecting portion which extends under the handle of the first member and is connected to the leg of the first member at a pivot pin. This enables the two members to pivot relative to each other. The pivot pin extends through a slot in the connecting portion of the second member to permit the two sections to shift relative to each other to vary the spacing between the gripping shoes. The legs are spread apart by pressing the handle toward the connecting portion, and in this condition the tool is installed over the object to be lifted with the shoes opposite the end walls of the object. When the tool is lifted upwardly at its handle, the gripping legs move together, causing the shoes to bear against the end walls of the object. The weight of the object coupled with the leverage developed between the gripping members results in a sizeable gripping force on the object.
