ABSTRACT:
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.
