An outrigger beam assembly for stabilizing large construction vehicles includes two pivotally connected portions. Mounted to an outer end of a single stage outrigger beam is an extension beam with selectively removable pins securing the extension beam to the outrigger beam. When a vertically aligned pair of pins are removed, the extension beam may be manually pivoted, around a vertical hinge axis passing through the remaining pins, from a working position to a non-working or storage position. Either a locking bar or cooperating apertured ear portions on the extension beam and the outrigger beam may be used to secure the extension beam in the storage position.
