Abstract

Abstract A load stabilizer is attached to an aircraft and projects therefrom and is shaped so that as a load is elevated on a winch, either projections on the load or the load-carrying beam engage a continuous cam member contoured to intercept the load projections or the load beam and guide the beam into a retaining slot so as to stabilize the load in a selectively oriented position and without respect to the attitude or orientation of the load during the load-elevating process.
