Abstract
Apparatus for unloading a load from a container having a floor, includes 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 pull sheet placed on the top surface of the floor sheet, the pull sheet having a bottom surface with a coefficient of static friction less than about 0.5. The pull sheet has a tensile strength sufficient to enable the pull sheet to be pulled from the container while maintaining the load on the top surface of the pull sheet to unload the load from the container.
Claims18
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.
A method of unloading a load from a container having a floor, comprising:
- positioning a floor sheet on the floor of the container, the floor sheet having a top surface with a coefficient of static friction less than about 0.3;
- positioning a first pull sheet 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;
- placing a first portion of the load on a top surface of the first pull sheet;
- positioning a second pull sheet on the top surface of the floor sheet, the second pull sheet having a bottom surface with a coefficient of static friction less than about 0.5;
- placing a second portion of the load on a top surface of the second pull sheet;
- pulling the second pull sheet from the container while maintaining the load on the top surface of the second pull sheet to unload the load from the container;
- and
- pulling the first pull sheet from the container while maintaining the load on the top surface of the first pull sheet to unload the load from the container.
A method of unloading a load from a container having a floor, comprising:
- positioning a floor sheet on the floor of the container, the floor sheet having a top surface with a coefficient of static friction less than about 0.3;
- positioning a first pull sheet on the top surface of the floor sheet, the first pull sheet having a load portion and an extension portion, the load portion having a bottom surface with a coefficient of static friction less than about 0.5 and being adapted to receive the load, and the extension portion being adapted to extend away from the load portion for pulling the first pull sheet from the container;
- placing a first portion of the load on a top surface of the first pull sheet;
- positioning a second pull sheet on the top surface of the floor sheet, the second pull sheet having a load portion and an extension portion, the load portion having a bottom surface with a coefficient of static friction less than about 0.5 and being adapted to receive the load, and the extension portion being adapted to extend away from the load portion for pulling the second pull sheet from the container;
- placing a second portion of the load on a top surface of the second pull sheet;
- extending the extension portion of the second pull sheet;
- pulling the second pull sheet from the container by pulling the extension portion relative to the container while maintaining the load on the top surface of the second pull sheet to unload the load from the container;
- extending the extension portion of the first pull sheet;
- and
- pulling the first pull sheet from the container by pulling the extension portion relative to the container while maintaining the load on the top surface of the first pull sheet to unload the load from the container.
