An apparatus and method for stabilizing a gantry. Powerful springs in the apparatus allow small deviations from a perpendicular configuration of a boom and beam arrangement. The springs resist larger deviations, thereby increasing the structural integrity and safety of the apparatus and method. The method stabilizes the gantry by providing a progressively increasing restoring force as the boom and beam travel farther from a starting position corresponding to a perpendicular relationship between the boom and the beam.
