Abstract: The present invention is a modular system for delivering material directly to a blender hopper. The system includes primary base and optional secondary base modules supporting surge hoppers which receive material from material containers. The surge hopper may then dispense the material directly and rapidly to the blender hopper by gravity feed. During continuous operation, exhausted material containers may be removed from the surge hoppers and replaced with full material containers as material empties from the surge hoppers. This allows steady, high-volume flow of material to the blender hopper.

Abstract: A material transport system and method having a frame with a plurality of upright frame members, upper lateral frame members, central lateral frame members, and lower lateral frame members. In one aspect, removable sidewalls can be affixed to the frame. In other aspects, the removable sidewalls have a density that is less than the density of the frame members. In other aspects, a modular container can be disposed in the frame. The frame can be constructed from a material having a lower density than the materials used for the frame.

Abstract: A cargo container is modified to carry a fracing proppant such as sand from a quarry or source to the frac site. Openings are cut in the top and bottom of a cargo container and hydraulically operated sliding doors are placed there under. A hopper module with the walls being inclined to approximately the angle of repose for the proppant is installed inside the cargo container. The hopper module is sealed inside the cargo container so that a proppant enters through the top opening at the quarry and flows out through the bottom opening at the fracing site. Once transported to the frac site, the modified cargo container is lifted, emptied and set aside.

Abstract: The present device and system provide rigid, stackable storage and transportation platforms. Vertical posts interconnecting side and end beams incorporate upper and lower connection pin plates. In use, these pin plates allow connection of the platform to transport means or stacked connection to other platforms using ISO lock pins. Cross beams extending between the side beams provide additional strength.
