Abstract

The present invention is a ramp having a front end that can be positioned up to the open end of a shipping container. The ramp has a back end adapted to receive the forks of a forklift for lifting and transport. Generally, the ramp is made up of an upwardly inclined support structure having an upper surface and a lower surface. A load-bearing plate having an outer surface, an inner surface, a front edge and a back edge is attached by its inner surface to the support structure'"'"'s upper surface. The back edge of the load-bearing plate includes at least one cutout section with a forward edge spaced above the support structure lower surface. At least one lift plate extends downwardly from the load-bearing inner surface. The at least one lift plate has a bottom surface that is substantially in a plane with the at least one cutout forward edge when the ramp is positioned horizontally.

Claims

1. A portable container ramp comprising:

a) an upwardly inclined support structure having an upper suds and a lower surface, wherein said upper surface is upwardly inclined when said lower surface is horizontal;

b) a load-bearing plate having an outer surface, an inner surface, a front edge and a back edge, said back edge including at least one cutout section with a forward edge spaced above said support structure lower surface, said load-bearing plate inner surface being attached to said support structure upper surface; and

c) at least one lift plate extending downwardly from said load-bearing plate inner surface, wherein said at least one lift plate has a bottom surface substantially in a plane with said at least one cutout forward edge when said ramp is positioned horizontally.

2. The ramp of claim 1, wherein said upwardly inclined support structure is a plurality of bracing plates extending downwardly from said load-bearing plate inner surface, each of said plates having a lower edge forming said support structure lower surface.

3. The ramp of claim 2, wherein a said lift plate extends downwardly between two of said plurality of bracing plates.

4. The ramp of claim 1, further including sidewalls having a lower edge forming said support structure lower surface.

5. The ramp of claim 4, wherein each of said sidewalls further includes a railing section that extends above said load-bearing plate upper surface.

6. The ramp of claim 1, further including a lip with a substantially horizontal lower surface and a downwardly inclined upper surface, said lip extending from the front edge of said load-bearing plate.

7. The ramp of claim 6, wherein the downward incline of said upper surface is approximately 10 degrees.

8. The ramp of claim 1, further including two spaced cutouts in said load-bearing sure back edge, wherein each of said cutouts have aligned front edges parallel to said load bearing plate back edge.

9. The ramp of claim 8, wherein said cutouts are spaced to receive forklift forks spaced at a given separation.

10. The ramp of claim 1, wherein said support structure is upwardly inclined from between a range of 5 to 45 degrees.

11. The ramp of claim 1, wherein said cutout forward edge is beveled downwardly from between a range of 5 to 45 degrees.

12. A portable container ram comprising:

a) a plurality of upwardly inclined equidistly spaced bracing plates having upper edges forming a support structure upper surface and lower edges forming a support structure lower surface, wherein said upper surface is upwardly inclined when said lower surface is horizontal;

b) a load-bearing plate having an outer surface, an inner surface, a front edge and a back edge, said back edge including at least one cutout section with a forward edge spaced above said support structure lower surface, said load-bearing plate inner surface being attached to said support structure upper surface; and

c) at least one lift plate extending downwardly from said load-bearing plate inner surface, wherein said at least one lift plate has a bottom surface substantially in a plane with said at least one cutout forward edge when said ramp is positioned horizontally.

13. The ramp of claim 12, wherein said at least one cutout section is sized to engage the fork of a forklift.

14. The ramp of claim 12, wherein the load-bearing surface is textured to prevent slipping.

15. The ramp of claim 12, wherein said upwardly inclined support structure is made of steel.

16. A portable container ramp comprising:

a) a plurality of upwardly inclined equidistantly spaced bracing plates having upper edges forming a support structure upper surface and lower edges forming a support structure lower surface, wherein said upper surface is upwardly inclined when said lower surface is horizontal;

b) a load-bearing plate having an outer surface, an inner surface, a front edge and a back edge, said back edge including two cutout sections with forward edges spaced above said support structure lower surface, said load-bearing plate inner surface being attached to said support structure upper surface;

c) sidewalls attached to said side edges of said load-bearing plate;

d) a forward bracing plate extending downwardly from said inner surface of said load-bearing plate in front of said bracing plates and extending between and transverse to said sidewalls; and

e) a pair of lift plates extending downwardly from said load-bearing plate inner surface between two pairs of said bracing plates, wherein said two lift plates have bottom surfaces substantially in a plane with said two cutout forward edges when said ramp is positioned horizontally.

17. The ramp of claim 16, when lifted by forklift forks has its weight distributed across the forklift'"'"'s forks at said cutout leading edges, said lift plates and said forward bracing plate.

18. The ramp of claim 16, wherein said load-bearing plate upper surface has a diamond plate texture.

19. The ramp of claim 16, wherein said each of said cutout forward edges is beveled downwardly at around 20 degrees.

20. The ramp of claim 16, further including sidewalls attached to said sidewall edges, each of said sidewalls having a railing section extending above said load-bearing plate side edges.
