A transportation vessel includes a first sidewall and an opposing second sidewall. A load bar has a first end and a second end. The load bar is movable between a horizontal orientation and a vertical orientation. In the horizontal orientation, the first end is attached to the first sidewall and the second end is attached to the second sidewall, and the load bar may support cargo while the cargo is being transported in the transportation vessel. In the vertical orientation, the first end is attached to the first sidewall and the second end is unattached to the second sidewall.

A vehicle intelligent lifting system, configured to be mounted to a vehicle body including a Controller Area Network (CAN) bus, is provided, including: a control module, in communication with the CAN bus, configured to obtain a signal from the CAN bus; a lifting device, in communication with the control module; wherein the control module determines whether to control the lifting device to operate according to vehicle information from the CAN bus.

A system to detect and avoid spilled cargo in an automobile vehicle, includes an automobile vehicle rear cargo area including a floor to temporarily receive a storage item in the cargo area. A lift gate is moved between a closed and latched position and a fully open position inclusive to allow loading and removal of the storage item. A vision system identifies the storage item when initially loaded in the cargo area and identifies if the storage item is initially positioned in a cargo spill position or subsequently moves to the cargo spill position. A cargo stop device is releasably connected to the lift gate. An operating system releasably stores the cargo stop device when the storage item is not in the cargo spill position and deploys the cargo stop device when the storage item is in the cargo spill position.

An embodiment of a lighting device for a lift gate includes one or more sensors, each sensor configured to generate an output signal based on motion and/or orientation thereof, wherein each sensor is coupled to a movable member of the lift gate to generate an output signal indicating a motion and/or position state of said movable member of the lift gate; a controller circuit coupled to each sensor to receive an output signal from each sensor, wherein the controller circuit is configured to generate one or more control signals for controlling operation of one or more lighting elements; and one or more lighting elements coupled to the controller circuit to receive control signals from the controller circuit; wherein the controller circuit is configured to generate one or more control signals in response to the output signals from each sensor, for controlling operation of one or more lighting elements based on sensed state of the moveable member.

A corner post is for a rear door of a trailer, container or truck body. The corner post has a width when the door has been swung open 90 degrees between 0.75 inch and 1.94 inch such that the width of the opening into the trailer when both doors are open is at least 98.44 inches. The corner post includes three pieces that are attached together. The three pieces include planar sections and U-shaped sections.

A transportation vessel includes a sidewall having a vertically oriented track on an interior side of the sidewall. The track extends upwardly to a top of the sidewall. A load bar has end(s) coupled to the track such that the end of the load bar is vertically slidable along the track. A stop bracket is positioned at a top of the track. The stop bracket includes a track extension and a stop piece. The track extension accommodates sliding of the load bar upwardly above the track. The stop piece blocks upward sliding of the load bar above the track extension.

A liftgate alert apparatus for alerting drivers when a liftgate is down before driving includes a pressure switch configured to be coupled to an air line of an airbrake system of a truck or a trailer. The pressure switch is closed when the airbrake system is activated. A roller switch is in operational communication with the pressure switch and is configured to be coupled to a liftgate. The roller switch is closed when the liftgate is in a down position. An alarm is in operational communication with the pressure switch, the roller switch, and a power source. The alarm has an alarm ground wire. The alarm is configured to be coupled within a cab of the truck or on a front end of the trailer and activates an audio and or visual alert when both the pressure switch and the roller switch are closed.

A trailer includes a front section having a first floor approximately between three and six feet above a street level. A rear section has a second floor approximately between three and six feet above the street level. A horizontally-oriented platform is disposed in the middle section. At least one linear actuator is coupled to the platform and selectively raises and lowers the platform between a lower position at most two feet above the street level and an upper position approximately between three and seven feet above the street level. Warning lights indicate a position and state of motion of the platform.
