ABSTRACT:
A cargo-handling apparatus which includes a cargo platform for airplanes which is structurally configured to prevent swaying of the cargo platform during loading and unloading of cargo from an aircraft. A pair of braced channel members are provided, which in their operative position extend vertically downward from both sides of the cargo hold of the aircraft, with a cargo platform positioned therebetween. The channel members are braced against movement by a pair of jury struts which extend between each channel member and the body of the aircraft, and a pair of cross braces extending between the channel members. The cargo platform moves up and down between and is guided by the channel members under the control of a power drive unit. The jury struts are disconnectable from the aircraft, and the combination of the jury struts, the braced channel members and the cargo platform is foldable such that the combination is stowable just inside the cargo hold door.
