ABSTRACT:
A dumping hopper and truck trailer washing stand used in connection with cleaning the interior of a truck trailer. The hopper and stand together form a trailer washing apparatus. The stand includes support legs that extend from a ground surface to a platform. Beneath the platform is a container storage area where the hopper can be positioned beneath the platform. To clean the interior of a truck trailer, a truck is positioned adjacent to the stand while the hopper is located below the platform. Waste material is washed from the interior of the trailer and onto the stand's platform. The waste material falls through a grate on the platform and into the hopper located below the stand. A frame structure on the hopper enables the hopper to be transported and vertically positioned by a fork lift. The hopper has a loading position where the hopper is in an upright position with waste material held therein and a dumping position where the hopper is in a tilted-downward position. When the hopper is in a dumping position and as the hopper is being lowered, the frame structure of the hopper is pressed against a ground surface. The pressing of the frame structure against the ground surface converts the force associated with lowering the hopper to a rotational force that rotates the container apparatus to an upright, loading position without the need of a motor.
