ABSTRACT:
A tool is provided for minimizing operator bending while lifting an elongated circular object, such as pipe. With one hand, the operator manipulates a slidable pin while grasping the tool handle. The slidable pin allows pivotable second grapple to move outward from the tool for positioning about the object, and, once the object encounters a trigger, to return the pivotable grapple toward the tool and secure the grapple in a position across from the first grapple, the first and second grapples being shaped to closely receive the object and hold the object between the grapples. A biasing element forces the slidable pin toward the pivotable grapple, the grapple being configured to receive the pin and be held in a position opposite the first grapple.
