Abstract:
An apparatus for unloading a load from a container having a floor, comprising:a floor sheet placed on the floor of the container, the floor sheet having a top surface with a coefficient of static friction less than about 0.3; a first pull sheet placed on the top surface of the floor sheet, the first pull sheet having a bottom surface with a coefficient of static friction less than about 0.5; wherein the first pull sheet has a tensile strength sufficient to enable the first pull sheet to be pulled from the container while maintaining the load on the top surface of the first pull sheet to unload the load from the container; and a second pull sheet placed on the top surface of the floor sheet, the second pull sheet have a bottom surface with a coefficient of static friction less than about 0.5; wherein the second pull sheet has a tensile strength sufficient to enable the second pull sheet to be pulled from the container while maintaining the load on the top surface of the second pull sheet to unload the load from the container.
