An automated mechanical loading system for loading seedling carriers into a transporter bin for transport to the field for planting. The system of the present invention includes a transport bin having a plurality of rails mounted on the inside walls of the bin for accepting a plurality of carriers, power driven projections slidably mounted on sleds which are fixedly mounted to the top frame of a lift for urging one or more carriers into a preselected set of opposing rails in the bin. The lift controls the height of the sled so that the carriers are urged into the preselected set of rails in the bin. A mechanically referenced coupler is included for securing the lift to the bin to restrict movement of the lift relative to the bin into which the seedling carriers are to be loaded during the automated loading operation.

Provided is a cargo carrying vehicle including; an elevating table 2 elevatable in the vertical direction; a plurality of rotating bodies 31 located on the elevating table 2 and configured to rotate so as to carry a cargo C in a conveyance direction X that is a direction toward a loading-unloading part of an aircraft; and a support 32 configured to support the plurality of rotating bodies 31, wherein the support 32 and the plurality of rotating bodies 31 constitute the conveying unit 3, and the conveying unit 3 is movable on the elevating table 2 in a position adjusting direction Y that is a direction intersecting the vertical direction and the conveyance direction.

A highway towable dock-lift trailer for use in loading and/or unloading trucks, rail cars, containers, etc., for example, in any location and across all industries and applications, and can include a tow bar that allows the trailer be towed to a desirable position or location. When the tow bar is removed from the trailer or repositioned relative to the frame, either a truck can back into position or the trailer lift can be positioned against the truck, etc., and the trailer lift is then ready to load and/or offload the truck. As an operator elevates the loading platform of the trailer, via hydraulic lifting means, for example, the lift can move up to truck height and hydraulically operated lifting arms can operate opposed automatic folding ramps, which simultaneously can open for load distribution and close for safety. The trailer can include a plurality of screw down or hydraulically actuated jacks to level and secure the platform, and the trailer can include bumpers to absorb the forces from a truck accidentally impacting the trailer.

Various embodiments are directed to unloading system and methods of using the same. In various embodiments, an unloading system comprises a trailer bed configured to receive a container thereon, wherein the trailer bed comprises one or more joints configurable between a plurality of joint positions, wherein the trailer bed is configured to lift, tilt, and oscillate at least a portion of the container based on the joints; and an extendable conveyor configured to receive a box that has been released from the container and convey the box away from the trailer bed. Various embodiments are directed to a method comprising tilting the container such that an open end of the container is lower than a closed end of the container, wherein the open end of the container is proximate to an extendable conveyor; and oscillating the container to facilitate release of a box from the container onto the extendable conveyor.

A transportation control system, a transportation device, and a transportation control method related to an automated transportation control method are used to provide automated transportation between platforms which are not interconnected. The transportation control method includes receiving a sensed signal which corresponds to a location of a transportation platform, generating a first motion command according to the sensed signal, transmitting the first motion command to a controller which controls the transportation platform, sensing a location of the transportation platform from different sensing locations to generate the sensed signal, transmitting the sensed signal through a network, and controlling the transportation platform to move by the controller in response to the first motion command.

The present disclosure discloses an automatic leveling control method for a four-leg support working platform, which comprises the steps: determining the mass center position of the working platform, determining the main bearing quadrant and distinguishing active legs from the driven leg; adjusting the driven leg to weak state, controlling all legs to synchronously actuate for leveling; calculating the limit compensating actuation length of the driven leg, and performing compensating actuation until accomplishing the leveling process. The method is advantageous in: high speed, high robustness, no repeated oscillation. The mass center always stays within the bearing zone of the active legs, thus completely eliminating capsizing risk of the working platform. The compensating actuation of the driven leg ensures there is no weak leg, and hence high attitude and load-bearing stability of the working platform is achieved.
