Ultra-lightweight, portable, and extremely low pressure dump system for handling dry or wet materials

Abstract

A dump system (e.g., for setting in a vehicle's flatbed or trailer) includes a base, a container (for containing material) configured to pivot relative to the base, an inflate membrane coupled to the base and to the container, and a U-frame that extends around the inflate membrane and is configured to pivot relative to the base. The U-frame is configured to restrain outward expansion of the inflate membrane as the inflate membrane expands pushing on the container and causing the container to pivot upward. Some implementations include, in addition to or instead of the U-frame, a wing frame panel configured to collect and contain folds that form from material of the inflate membrane as the inflate membrane deflates and collapses (or when the inflate membrane is in a collapsed or deflated state).

Dependencies are inferred from the claim text.
