A container unloading device which includes a two-tiered rail system that has been adapted to include an upper set of feed rails that cycle carts carrying containers from the back of the system to the front of the system for unloading. At the system\s front end, the feed rails have sections of increased angularity which support the cart and container at an angle which increases accessibility to the container\s contents. The system also includes a set of transfer ramps which allow the cart to move from rolling engagement with the feed rails to rolling engagement with the lower set of return rails where the cart and unloaded container then move to the back of the system into a position for reloading. The device may further include a speed reducer which retards the cart\s acceleration down the sections of increased angularity.

A container unloading system having an unloading front end and loading rear end comprising: a two-tiered rail system having a set of parallel feed rails and a set of parallel return rails positioned below said feed rails; said feed rails having sections of increased angularity near said front end; at least one cart having a load bearing surface adapted to carry a unit load and further including support means for the attachment of front and rear wheels; said wheels positioned on said cart for rolling engagement with said feed rails and said return rails of said two-tiered rail system; a first set of passageways located above said return rails, said first passageways adapted to permit said rear wheels of said cart to move from rolling engagement with said feed rails to rolling engagement with said return rails; a second set of passageways located above said return rails, said second passageways adapted to permit said front wheels of said cart to move from rolling engagement with said feed rails to rolling engagement with said return rails; said cart selectively retained on said feed rails during the unloading of said cart; said rail system adapted for said cart to be supported on said sections of increased angularity during the unloading of said unit load; and a speed reduction means for controlling said cart\s descent down said sections of increased angularity.
