Abstract
A clamp for clampingly engaging a portion of a workpiece and for lifting the workpiece from a work surface. The clamp comprises a fluid actuated piston and cylinder assembly, a frame assembly, first and second clamp arms supported by the frame assembly for pivotal movement about respective first and second pivot axes and axial movement parallel to the longitudinal axis between an unclamped position and a clamped and lifted position, first and second pivot pins respectively defining the first and second pivot axes, first and second slider members respectively supported in first and second tracks for axial movement relative to frame assembly and respectively supporting the first and second pivot pins for axial movement along the first and second tracks relative to the frame assembly, first and second link pins supported proximate the opposite ends of the first and second clamp arms, respectively, the first link pin being movable along the first arcuate track and the first track and the second link pin being moveable along the second arcuate track and the second track, first and second link members connecting the first and second link pins, respectively, to the piston such that movement of piston between the extended position and the retracted position causes movement of the first and second clamp arms between the unclamped position and the clamped and lifted position.
