A roller rail assembly for a cargo loading system for loading cargo-loaded pallets into a vehicle, such as an aircraft. The roller rail assembly is removably mounted in a track or channel assembly having alternate cutout portions and lip portions. The roller rail assembly includes an elongated rail member which has a tension stud extending substantially normally from the main body of the assembly along the bottom edge thereof, and a support shoulder extending from the main body of the assembly substantially normally thereto above the tension stud and in a substantially opposite direction thereto. Mounting blocks and axles are provided for rotatably mounting pairs of rollers on the main body of the assembly, the rollers being positioned on opposite sides of the track for rotation on an axis substantially normal to the longitudinal axis of the track. The rail is removably supported in the track with the tension stud fitted underneath the lip portions of the track. A retainer member has a tension lug extending normally therefrom along the bottom edge thereof and a shear lug spaced above and running in substantially the same direction as the tension lug. With the tension stud of the rail installed under the lips along one side of the track, the retainer member is rotated to bring the tension lug thereof under the lip portions of the opposite side of the track and the shear lug thereof into one of the cutout portions of the track, the retainer member being bolted to the rail in this installed position. |
