Aspects of the present disclosure provide an automatic self-unloading material handling system that replace conventional material handling unloading systems. The automatic material handling unloading comprising a container with a roller assembly floor; a moveable bulkhead; a control enclosure; gear drive guide track assemblies; gear drive assemblies; a power track; a battery; and a power collector. Particularly, an Automatic self-unloading material handling system constructed as set out herein, can be configured and programmed to satisfy user-specified dimensions and load ratings, dynamic loading, ect, while provide a material handling unloading system that is lighter than what is realized in conventional unloading systems at comparable dimensions and load ratings. The automatic self-unloading material handling system is programmable with automated features to unload cargo from a container autonomously.

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.

A stowable cargo guide may be configured to couple to a roller tray. The stowable cargo guide may comprise a guide block configured to rotate between a stowed position and a raised position. In the stowed position, the guide block may be located below a conveyance plane of the roller tray. In the raised position, the guide block may be located above the conveyance plane of the roller tray.

An apparatus is for collecting and transporting bales. The apparatus includes a transport assembly and a grasping assembly operatively connected thereto. The transport assembly includes a bale loading platform extending above and mounted to a chassis. The bale loading platform comprises at least one bale conveying section in including a bale conveying mechanism. The grasping assembly includes a mechanical arm having a prehension end effector engageable with the bales. The grasping assembly is configurable between a bale engagement configuration for engaging a corresponding one of the bales laying on the ground, a bale capture configuration for capturing and lifting the corresponding one of the bales off the ground and a bale release configuration for releasing the corresponding one of the bales onto the bale loading platform and comprises a movement absorption mechanism operative to substantially cancel the forward displacement of the apparatus during the capture of the bales.

An assistance vehicle tilt lift supports an assistance vehicle above a bed of a hauling vehicle and includes one or more pivoting racks. Each pivoting rack includes a track to receive one or more wheels of the assistance vehicle. Each pivoting rack is rotatably attached to a pivot point near the front end of the bed of the hauling vehicle. One or more tapered rails are attached to the bed of the hauling vehicle. One or more roller support members are in contact with the one or more tapered rails and rotatably attached to the one or more pivoting racks. An actuator is operably connected to the one or more roller support members. The actuator raises and lowers the rear end of the one or more pivoting racks relative to the pivot point by moving the one or more roller support members along the one or more tapered rails.

An amphibious air cushion vehicle includes an air cushion supported hull configured for travel on water and smooth land; a deck supported by the hull; and a dual-rail cargo system having tracks arranged longitudinally on along the hull cargo deck from an aft end. The tracks include (1) guide rails and rollers providing for guided sliding movement of palletized cargo along the tracks, and (2) locks for locking pallets in position during transport, The track is configured at the aft end for an unloading operation in which the locks are disengaged and the palletized cargo slides off the aft end onto underlying land as the vehicle is moving forward thereon. The track may be the one track of a single-track variant, or one of a pair of tracks in a two-track variant.
