  • Patent number: 4355940
    Abstract: An automatic loading platform for facilitating the loading and unloading of palletized loads is provided. The platform comprises an upper surface and an inclined ramp. A plurality of rotatable drive rollers extend above the upper surface to support a load, and the upper surface includes a plurality of air exit ports to provide a fluid bearing surface for the load. The drive rollers rotate in response to the rotation of carrier rollers and wheels, such response occuring only after air is supplied to the frame, and after the carrier rollers rotate in response to translational movement of the platform. A method for unloading a load from the platform by creating relative motion between the platform and load is thereby provided.
