The apparatus comprises a clamping assembly adapted for mounting on a lift mechanism of a lift truck with opposed load engaging and gripping platens forwardly thereof. Link members connect the platens to the lift assembly whereby when the opposed platens are in contact with the load under at rest condition and the lift assembly is then moved vertically upward said platens will be moved inwardly toward each other to frictionally and firmly grip the load therebetween for lift purposes.
