Support apparatus for moving proppant from a container in a proppant discharge system

A system to move proppant from a plurality of proppant containers, the system comprising:

• a plurality of containers each having proppant stored therein, each of the plurality of containers having ramps to direct proppant through an opening at a bottom of the container when proppant is positioned in the container, the opening being covered by a gate that is movable between an open position that allows proppant to flow through the opening and a closed position that blocks proppant from flowing through the opening;
• a frame having a surface positioned to receive a plurality of containers when positioned thereon, the frame including spaced apart rails forming at least a portion of the surface, a plurality of legs extending downwardly from respective corners of the frame, and open areas positioned between the legs to grant visual access to an area below the surface of the frame;
• and
• one or more hoppers positioned below the surface and connected to the frame such that an inlet to each of the one or more hoppers is proximate the spaced apart rails, the one or more hoppers each including an opening adjacent a lower end thereof, the one or more hoppers being positioned to receive proppant from one or more of the plurality of containers when the one or more of the plurality of containers is positioned on the surface of the frame and the gate of the one or more of the plurality of containers is in the open position.
