A self-loading pallet system is disclosed where a three-dimensional basic structure can be manipulated horizontally and vertically and carry with it a cargo, loaded either directly into the structure, or onto a separate pallet structure inserted into the basic structure. The system is useful for loading and unloading cargo between ground level and the cargo floor of vehicles. The vertical loading steps are accomplished by a sequence of extensions and retractions of legs slidably attached to the basic structure. The vertical leg movements are powered by actuators that extend and retract their pistons attached to telescoping legs of the basic structure. Each actuator has an interior motor and a dedicated controller operating the motor. An exterior master controller communicates with each actuator controller, whereby the sequence of vertical loading steps can be pre-programmed to effectively automate the loading and unloading sequences. Actuator motors are powered by an exterior rechargeable battery.

A selectively lowerable and raisable vehicle trailer system for raising and lowering of a vehicle trailer to expedite loading and unloading of cargo includes a rear wheel assembly. An elongated trailer is pivotally supported by the rear wheel assembly. The trailer is positional between a horizontal transport orientation and a sloped or angled loading/unloading orientation on the rear wheel assembly. The rear wheel assembly is selectively adjustable in position along the trailer between a rear transport position and a forward loading/unloading position, rearward and forward of the trailer center of gravity, respectively. A wheel assembly adjustment mechanism engages the rear wheel assembly. The wheel assembly adjustment mechanism operably engages the rear wheel assembly to facilitate selective positioning of the rear wheel assembly between the transport position and the loading/unloading position. A method of loading and unloading cargo onto and from a vehicle trailer is also disclosed.

Package sorting systems and methods of use are disclosed herein. An example system includes a platform of a vehicle, where the platform is arranged as a grid having a plurality of slots (including an open slot and a target slot). A plurality of slabs can be placed into the grid except for in the open slot. A slab moving assembly is used, to move the slabs in order to place a selected slab into the target slot on the platform.

An apparatus for delivering proppant to a well site includes a plurality of proppant containers. The apparatus also includes a support structure having a bed and a structural framework extending down from the bed. The plurality of proppant container are structurally supported on top of the bed. A bin is disposed within the structural frame work below the bed. A conveyor cooperates with the bin for transporting proppant from the bin to a desired location at the well site. Proppant discharged from one or more of the plurality of proppant containers positioned on the bed above the bin is received in the bin and delivered to the well site by the conveyor.
