ABSTRACT:
An outrigger pad for placement between ground and the foot of an outrigger mechanism to support or level such outrigger mechanism that laterally stabilizes vehicular machinery and the like, wherein the pad which may be of one piece cast metal construction comprises a base having a generally planar lower surface, a second generally planar upper surface, the planes of the two surfaces defining an oblique angle with respect to one another, the lower planar surface having gripping means in the form of an annular array of concentric ribs adapted to penetrate the ground to restrict lateral movement and the upper surface has interfitting means in the form of a centrally located tubular member and a plurality of radially extending ribs with an annular array of notches in the upper surface ribs corresponding to the lower base surface ribs so that pads of the same construction may be stacked and rotated with respect to one another to vary the effective surface angle of the topmost one of such stacked pads.
