There is disclosed a dry bulk hopper system that includes a generally frustoconical bottle and a base having a tapered wall that defines a cradle for holding the bottle. The bottle has locking tabs disposed at bottom end thereof that cooperate with engagement ledges to secure the bottle to the base when the bottle has been received into the base in a first orientation, but not in a second orientation. Extruded support columns are disposed inside an interior of the base to distribute loads created by material in the bottle when the system is raised by a forklift.

Improved equipment bases and methods for making and using same are disclosed herein. The equipment base can include a first coated substrate including a first part having a first thickness sized to provide the load-bearing support for the equipment, a first elastomer coating the first part, a second coated substrate positioned adjacent to the first coated substrate, the second coated substrate including a second part having a second thickness sized to provide the load-bearing support for the equipment, and a second elastomer coating the second part. A first seam can be formed between the first and second coated substrates to allow for moisture to pass between the first and second coated substrates so that moisture is allowed to seep away from the bottom of the equipment.

A mobile tower system includes a steel shipping container. A tower structure is moveable between a substantially horizontal travel position and a substantially vertical operational position. A connection member is fixed to a lower portion of the tower structure and moveably coupled to a channel disposed in a horizontal member removeably attached to a vertical frame attached to a back wall of the steel shipping container. When the tower structure is displaced from the substantially horizontal travel position to the substantially vertical operational position, the connection member and the tower structure are linearly displaced together along the channel toward the back wall and the tower structure is pivotably displaced about the connection member, such that the upper portion of the tower structure is displaced through an opening disposed in a roof of the steel shipping container proximate a back wall of the steel shipping container.

The present invention provides an apparatus, method and system for utilizing commercial cargo containers. The present invention utilizes containers made autonomous by coupling a container with a detachable propulsion system, having a motor and navigation and steering controls, permitting the rapid, controlled, efficient and safe delivery of cargo containers individually by water. Ballast units, deployment systems and control via remote units are also disclosed. The containers, utilizing their inherent buoyancy, can move autonomously according to a preplanned or remote controlled route to a specific location.

A load carrier for an aircraft cargo hold includes a bottom element with a support surface, the load carrier being movable over a floor surface in a floor plane while the support surface faces the floor surface, the bottom element having a base surface. The support surface has rolling elements rotatable about a rotation axis oriented where a parallel to the axis runs parallel to the floor plane, and the rolling elements being retained on the bottom element where the rotation axis of each of the rolling elements can be rotated about a vertical axis running perpendicularly to the floor plane. A load carrier can include a bottom element, the support surface of which has outlet openings, through which air can exit from the support surface to form an air cushion under the support surface. A load carrier can include a bottom element the support surface of which has slider elements.

An apparatus to support a proppant container includes a frame to receive and support the proppant container. The frame has a top surface that receives and positions the proppant container in an elevated position. The apparatus also includes a box guide assembly positioned on the top surface a box guide assembly connected to the top surface of the frame for defining a cradle section having four corners. The box guide assembly including a box guide positioned at each of the corners. Each box guide has a corner member extending upwardly from the top surface along a peripheral edge of the frame and a guide member extending adjacent the corner member. The guide member include an inclined face for aligning the proppant container in the cradle section. The box guide assembly guides the proppant container into the cradle section when loaded onto the frame in the elevated position.
