  • Patent number: 4684311
    Abstract: Load transporting apparatus enables loads to be transported on and off vehicles. The apparatus requires a loading platform to be located adjacent a load receiving surface of a vehicle. The platform and the surface each have channel shaped tracks which are aligned with one another. An inflatable tube on which is carried a plate is located in the base of the channel and skates are arranged to be moved along the plates when the tube is inflated. Thus the skates can move along the channels supporting a load when a transfer to or from the vehicle is required. When in position deflation of the tube causes the skates to lower and the load rests on the associated surface. In the deflated position the skates can be moved along the tracks out of engagement with the load. The plates have a central depression to ensure that the skates remain centrally located in the tracks.
