Abstract:
A clamp for clampingly engaging a portion of a workpiece and for lifting the workpiece from a work surface, said clamp comprising:a frame assembly defining a longitudinal axis and a track, the frame assembly including a body portion formed of a first material and an insert connected to the body portion and formed of a second material, the second material being harder than the first material, the insert defining at least a portion of the track; an actuating assembly supported by the frame assembly and including a movable member movable between a retracted position and an extended position; a clamp arm supported by the frame assembly for pivotal movement about a pivot axis and for axial movement relative to the frame assembly along the longitudinal axis, the clamp arm being connected to the movable member so that the clamp arm is movable between an unclamped position, in which the workpiece is not clampingly engaged by the clamp arm, and a clamped and lifted position, in which the workpiece is clampingly engaged by the clamp arm and is lifted from the work surface by the clamp arm; and a pin supported by the frame assembly for movement in the track, the pin connecting the clamp arm and one of the frame assembly and the movable member.
