ABSTRACT:
A billet grab includes opposed grips that are movable toward or away from one another in a direction perpendicular to their lengths. One grip is provided with a plurality of identical cams pivotally mounted on it to engage the ends of billets or other objects having identical or slightly varying lengths and arranged side by side in a row. The inwardly biased cams accommodate the varying lengths of the billets or objects, which can then be lifted as a group. Frictional engagement between the inner cam surfaces and the ends of the billets or other objects assure proper gripping of each billet or object in the row as it is being lifted and handled. The cams are disengaged by spreading the grips apart from one another.
