AbstractA grapple clamp for lifting a group of objects such as a plurality of cases of soft drinks. The clamp has four clamp jaws hinged to a frame in rectangular or square orientation so as to engage a group of objects with equal force from four sides. The clamp is adapted to be carried by a fork lift truck and each pair of opposing jaw clamps is actuated by a hydraulic or pneumatic cylinder. Preferably, hydraulic cylinders are used which are powered by the hydraulic system of the lift truck. The cylinders are interconnected so that the clamping forces exerted by the two pairs of clamp jaws are equalized.
