A trailer system for a vehicle includes a trailer having a trailer body, wheels, and a trailer tongue for hitching the trailer to a towing vehicle. A rear end of the trailer body is pivotally and detachably attachable at a rear of the vehicle. When attached at the rear of the vehicle, the trailer is pivotable between a stowed position, where the trailer is vertically oriented along the rear of the vehicle, and a lowered position, where the trailer is lowered such that the wheels are at the ground. When attached at the rear of the vehicle and in the stowed position, the front end of the trailer body is at or near an upper region of the vehicle. When attached and in the lowered position, the trailer functions to allow items to be unloaded from the vehicle and onto the trailer body.

An interlocking tailgate utility bar for a vehicle having a tailgate at least partially defining a cargo area includes a top surface, a bottom surface opposite the top surface and configured to be disposed against an inner wall of the tailgate when the tailgate is in an open position, opposed front and rear side surfaces, and opposed ends. A striker assembly is disposed at each end of the opposed ends and includes a striker configured to be releasably coupled to tailgate latches located on opposed sides of the tailgate to thereby selectively releasably secure the interlocking tailgate utility bar to the tailgate. A rail channel is configured to receive an attachment device of a vehicle accessory to thereby removably couple the vehicle accessory to the interlocking tailgate utility bar and thus the vehicle.

An excavation system may include a base unit, a boom mounted on the base unit, a pair of drag ropes coupled with the boom, and a robotic bucket mechanism attached to the pair of drag ropes. The robotic bucket mechanism may include an undercarriage drive, a chassis mounted on the undercarriage drive, an excavating bucket mounted on the chassis, a pair of hydraulic lift actuators coupled between the chassis and the excavating bucket at pivot points on both sides of the excavating bucket, and a hydraulic tilt actuator mounted between the chassis and a rear side of the excavating bucket.

A motor vehicle includes a ramp, a sliding door that when open allows the ramp to be deployed from the vehicle, and an anti-rattle device to prevent or reduce rattling of the ramp against the door or other components of the vehicle when the ramp is in a stowed position. The anti-rattle device includes an arm pivotable relative to the door and a roller rotatably coupled to the arm, spaced apart from the door, and configured to contact the ramp.

A vehicle slope apparatus includes a slope plate configured to be deployed at a lower end of a door opening portion, a guide rail extending in deployment and housing directions of the slope plate, a moving member configured to move along an extending direction of the guide rail, a support arm rotatably connected to a rear end of the slope plate and rotatably connected to the moving member, and a lift mechanism configured to lift the rear end of the slope plate by rotating the support arm in a state where the slope plate is deployed. The support arm is provided with a roller configured to hold a moving posture of the slope plate by being in sliding contact with the guide rail in a state where the slope plate is moved integrally with the moving member.

A unified hinge may comprise a hinge tube that is rigidly attached to a truck frame and a bed section of a truck bed and a tail section of the truck bed, each of the bed section and the tail section having opposing hinge barrels affixed thereto that concentrically align on the hinge tube. Similarly, a unified hinge may comprise one or more mounting barrels that are rigidly attached to a truck frame and a bed section of a truck bed and a tail section of the truck bed, each of the bed section and the tail section having opposing hinge barrels affixed thereto that concentrically align on the one or more mounting barrels; a hinge tube runs through the one or more mounting barrels and the opposing hinge barrels. The unified hinge allows the bed section and the tail section to independently pivot along the hinge tube.

A towable trailer vehicle is provided having a pass-through cart treatment chamber formed from lateral side to side between two ramp doors. The chamber forms a spray tunnel in which carts are moved by a conveyor from various treatment stations to the next, and which can include cleaning, sanitizing and/or disinfecting, rinsing, drying, and applying protective coatings to each cart. The various fluids used in the spray treatment are stored, prepared, controlled, and collected for reuse and/or disposal within the trailer. The trailer is dimensioned to allow sufficient advertising, information, and/or aesthetic decor thereon to facilitate its use and desirability. The trailer structure provides apparatus security during periods of non-use.

A ramp assembly comprises a support defining a vertical and horizontal pivot axes and a ramp with a first ramp portion coupled at one side thereof to the support, a second ramp portion, and a hinge connecting the second ramp portion to the first ramp portion. The second ramp section is manually movable between a generally folded stowed position being disposed in a surface-to-surface facing arrangement with the first ramp section and an unfolded deployed position being disposed in an end-to-end facing arrangement with the first ramp section. The ramp is manually pivotable on the support, about the vertical and horizontal pivot axes, between a folded stowed position, an unfolded deployed position defining an inclined ramp surface, and a folded intermediate position. The ramp can be installed on a vehicle for use by non-ambulatory passengers and be disposed in a position allowing unhindered use of the vehicle by ambulatory passengers.

Improved passenger access and suspension systems for passenger buses, and controllers configured for use therewith; and passenger buses incorporating such systems and controllers. Integration of access ramp, door, suspension, charge interface, and other systems provides improvements in fully- or semi-automatic deployment of features such as passenger doors and ramps, and charge interface components, as well as navigation to passenger access points.
