A heavy-duty cargo bin unit configured for rugged use in hostile environments, such as in the oil drilling and production industry. The cargo bin unit is of a generally rectilinear construction, and preferably fabricated of heavy gauge steel. Supports or skids are positioned to allow for the nested stacking of one cargo bin atop the other, such that the lower portion support members would fit snugly within the interior walls of the cargo bin upon which it is placed. The size and configuration of the basket may vary depending upon the application, and the unit may be configured to receive templates for the customized storage of particular items such as drilling tools, bits, etc. A second embodiment of the present invention contemplates a cargo bin dumping system wherein there is provided a cargo bin as disclosed in the preferred embodiment of the present invention, with a stinger specifically designed to work with the present system also provided.

What is claimed is: 1. A stackable bin system for use with a forklift having first and second forks, comprising: first and second cargo bins, each comprising: first and second vertical walls having first and second ends joined by first and second end walls, respectively, to form a bin having an inner width and opposing top and bottom edges; an integrated floor having upper and lower surfaces joining said first and second vertical walls and said first and second end walls to form a bin holding area having an upper edge, a length, and a width; a rigid framework frame forming said edges of said bin, said framework defining the periphery of said first and second vertical walls and said first and second end walls, said framework further comprising vertical support members having first and second ends, said first end of said vertical support members affixed to said bottom edge, said second end of said vertical support members engaging said top edge, and first and second stringers horizontally aligned and situated between said opposing bottom edges, so as to reinforce said floor; first and second aligned braces situated between said first and second stringers to reinforce said first and second stringers and said floor; first and second skids engaged to said lower surface of said floor, said skids formed to space said lower surface of said floor from a support surface so as to allow first and second forks from a forklift to pass therebetween, each of said skids having first and second ends and a length therebetween; said skids of said first cargo bin having a recess (26) formed at each of said first and second ends, respectively, each recess defining an inner edge (27, 27') formed to rest within the bin holding area of said second cargo bin when stacked thereupon, and each said recess formed to interface with said upper edge of said second cargo bin when stacked thereupon, so as to resist sliding or tilting. 2. The cargo bins of claim 1, wherein said frame is formed of tubing. 3. The cargo bins of claim 2, wherein said tubing has a square cross-section. 4. The cargo bins of claim 3, wherein said first and second vertical walls and said first and second end walls form first, second, third and fourth corners, and wherein there is provided first, second, third and fourth pad eyes emanating from said first, second, third and fourth corners, respectively, said pad eyes situated in the vicinity of, but below said upper edge of each of said bins. 5. The cargo bins of claim 4, wherein there is further provided a layer of heavy gauge expanded metal (7) situated between said vertical support members (12) to form said first vertical wall. 6. A cargo bin, comprising: first and second vertical walls having first and second ends joined by first and second end walls, respectively, to form a bin having an inner width and opposing top and bottom edges; an integrated floor having upper and lower surfaces joining said first and second vertical walls and said first and second end walls to form a bin holding area having an upper edge, a length, and a width; a rigid framework frame forming said edges of said bin, said framework defining the periphery of said first and second vertical walls and said end walls, said framework further comprising vertical support members having first and second ends, said first end of said vertical support members affixed to said bottom edge, said second end of said vertical support members engaging said top edge, and first and second stringers horizontally aligned and situated between said opposing bottom edges, so as to reinforce said floor; first and second aligned braces situated between said first and second stringers to reinforce said first and second stringers and said floor; first and second skids engaged to said lower surface of said floor, said skids formed to space said lower surface of said floor from a support surface so as to allow first and second forks from a forklift to pass therebetween, each of said skids having first and second ends and a length therebetween; each of said first and second skids having a recess formed at each of said first and second ends, respectively, each recess formed to interface with upper edges of a second cargo bin, each recess also defining an inner edge to rest within a bin holding area of said second cargo bin when stacked thereupon, so as to resist sliding or tilting. 7. The cargo bin of claim 6, wherein said first and second vertical walls and said first and second end walls form first, second, third and fourth corners, and wherein there is provided first, second, third and fourth pad eyes emanating from said first, second, third and fourth corners, respectively, said pad eyes situated in the vicinity of, but below said upper edge of each of said bins. 8. The cargo bin of claim 6, wherein there is further provided a layer of heavy gauge expanded metal (7) situated between said vertical support members (12) to form said first vertical wall. 9. The cargo bin of claim 8, wherein said frame is formed of tubing having a square cross-section.
