A swing arm style grappler for a gantry crane is equipped with contact shoes configured to engage in horizontal, flush contact at the underside of a standard load. The grappler includes a plurality of pivotable arms movable between an unclamped position, wherein the arms are positioned outwardly free from the load, and a clamped position wherein the arms are positioned inwardly to clamp the load. Each of the arms has an elongate portion, one of the shoes being mounted to a lower end of the elongate portion. The shoe includes a lifting shelf which projects generally inwardly at an angle such that, when the arms are in the clamped position, the shelf is horizontal.
