A load carrying device configured to support and transport a tray comprising a platform configured to support the tray, rolling means depending from the platform, and a retainer disposed on the platform and configured to loosely abut the tray to limit movement of the tray across the platform when the tray is supported on the platform. The retainer limits movement of the tray in all directions across the platform when the tray is supported on the platform. The retainer projects upwardly from the platform and presents a surface opposing horizontal movement of the tray when the tray is supported on the platform. The tray includes a bottom surface, a first pair of opposed walls projecting upwardly from the bottom surface, a second pair of opposed walls projecting upwardly from the bottom surface and integrally joined with the first pair of opposed walls, and a plurality of support members projecting below the bottom surface and configured to be supported by the platform, wherein the bottom surface is configured to clear the retainer when the support members are supported on the platform, and wherein the support members oppose and loosely abut the retainer when the support members are supported on the platform.

1. A load carrying device configured to transport a tray, the tray including a base having a bottom surface and a plurality of support members projecting below the bottom surface, the load carrying device comprising:a platform having a support surface configured to support the support members; rolling means depending from the platform; and a retainer comprising a retainer wall spaced inwardly from the perimeter of the platform and projecting above the support surface and being configured to oppose horizontal displacement of the tray when the support members are supported on the support surface, and a raised surface disposed vertically above and integrally joined by the retainer wall to the support surface; wherein the raised surface is spaced inwardly from the perimeter and the support surface is disposed between the perimeter and the retainer wall, and wherein the raised surface is configured to provide support to the base of the tray when the support members are supported on the support surface, and wherein the raised surface includes a perimeter, and a recessed channel extending adjacent the perimeter, and stiffening means comprising a plurality of ribs intersecting the channel. 2. The load carrying device as claimed in claim 1, wherein the retainer is configured to oppose horizontal displacement of the tray when the support members are supported on the support surface.3. The load carrying device as claimed claim 1, wherein in the retainer is configured to limit horizontal displacement of the tray when the support members are supported on the support surface, for maintaining the support of the support members by the support surface.4. The load carry device as claimed in any of claims 2 or 3, wherein the support members loosely abut the retainer wall.5. The load carrying device as claimed in claim 4, wherein the recessed channel extends adjacent and substantially about the entire perimeter wherein the stiffening means comprise a plurality of ribs intersecting the channel substantially about the entire perimeter.6. The load carrying device as claimed in claim 1 or 5, wherein the raised surface includes an aperture spaced from the perimeter of the raised surface.7. The load carrying device as claimed in claim 6, wherein the upper surface includes wells configured to receive rolling means of an identical load carrying device when the identical load carrying device is stacked upon the upper surface.8. A load carrying device configured to transport a tray, the tray including a base having a bottom surface and a plurality of support members projecting below the bottom surface, the load carrying device comprising:a platform having a support surface configured to support the support members; rolling means depending from the platform; and a retainer comprising a retainer wall spaced inwardly from the perimeter of the platform and projecting above the support surface and being configured to oppose horizontal displacement of the tray when the support members are supported on the support surface, and a raised surface disposed vertically above and integrally joined by the retainer wall to the support surface; wherein the raised surface is spaced inwardly from the perimeter and the support surface is disposed between the perimeter and the retainer wall, and wherein the raised surface is configured to provide support to the base of the tray when the support members are supported on the support surface, and, wherein the raised surface includes a perimeter, and a recessed channel extending adjacent the perimeter, and stiffening means defined by corrugations provided in the raised surface. 9. The load carrying device as claimed in claim 8, wherein the retainer is configured to oppose horizontal displacement of the tray when the support members are supported on the support surface.10. The load carrying device as claimed in claim 8, wherein the retainer is configured to limit horizontal displacement of the tray when the support members are supported on the support surface, for maintaining the support of the support members by the support surface.11. The load carry device as claimed in any of claims 9 or 10, wherein the support members loosely abut the retainer wall.
