ABSTRACT:
A cargo truck is provided having a loading ramp assembly to aid in loading and unloading items from a cargo box on the truck. The loading ramp assembly is adjustable between a loading position wherein a ramp is provided between a deck of the cargo box and the ground, and a storage position to allow transport of the cargo truck. The loading ramp fits within a pocket between the truck frame and the cargo box when in the storage position. The pocket is formed by long C-shaped box sills that support the cargo box. The ramp is formed by two side rails, a ramp floor between the side rails, and support braces between the ramp floor and the side rails to prevent buckling of the side rails upon application of a load to the ramp. The braces extend below the bottom of the box sills when the ramp is in a storage position. The braces allow for lower profile side rails, thereby reducing the amount the cargo box must be raised above the truck frame to accommodate the ramp assembly. The cargo box has cross members which set directly on the box sills without the need to be cut.
