Vehicle shelf systems having indicators thereon for improving loading and delivery efficiency. Items are scanned for loading, and the indicators on the vehicle shelves identify where to place the item based on the sequence of the delivery point along the delivery route. A mobile computing device alerts a delivery carrier when the delivery vehicle is in proximity to a delivery point when an item is to be delivered.

An apparatus and process for delivering proppant to a well site has a trailer with a bed thereon and at least one track of rollers extending in parallel relationship to the longitudinal axis of the trailer. The track of rollers extend substantially for an entire length of the bed of the trailer. At least one proppant container is translatably positioned on the track of rollers. The proppant container is movable along the array of rollers from one end of the bed to an opposite end of the bed. A bin can be removably positioned below the bed of the trailer in a position rearward of the front end of the trailer and forward of a rear end of the trailer so as to allow the proppant container to discharge into the bin. A conveyor is cooperative with the bin so as to move proppant from the bin to a location at the well site.

A rack includes a casing and a plurality of pairs of supports that is provided inside the casing so as to extend in a depth direction and arrayed at regular intervals in an up-down direction. The rack can house all storage boxes of two or more prespecified sizes while supporting the storage boxes so as to be slidable along the respective pairs of supports. Sensors that detect objects are provided one between each two pairs of supports that are adjacent to each other in the up-down direction among the pairs of supports. When storage boxes of a smallest size are housed in the rack so as to be closest to one another in the up-down direction, the sensors are located in clearances between the storage boxes of the smallest size in the up-down direction.

The transport system has a transport vehicle. The transport vehicle includes two racks, each of the two racks being configured to accommodate a plurality of boxes, and a drive arm that is disposed at a position between the two racks and that moves each of the boxes in and out of each of the racks. The transport vehicle moves each of the boxes in and out of each of the two racks by changing an orientation of the drive arm.

An intermodal container includes a base (100) having a defined number of sides. The base is configured to support products during transport. The intermodal container further includes a removable cover (104) having a top and a defined number of sides matching the defined number of sides of the base. The removable cover is configured to be releasably secured to the base to define an enclosure in a use position and to be removed and flattened in a stored position.
