Certain embodiments of the inventive technology may be described as an enclosed, mobile emergency response unit that comprises an enclosure and an underlying support frame on which the enclosure is established, where that enclosure may include a medical compartment that is unsecured when the enclosed, mobile emergency response unit is on operational standby, an onboard equipment compartment that is secured, when the enclosed, mobile emergency response unit is on operational standby, and a ramped, portable equipment compartment that is unsecured when the enclosed, mobile emergency response unit is on operational standby. Embodiments of the inventive technology may further include, e.g., a fire suppression system, a fueled electrical power generator, a compressor, a solar power system, medical equipment, wi-fi provision componentry and/or operational parameter monitors, among other componentry.

A method for driving a tractor on a flatbed trailer. The method includes locating a starting position of the tractor, determining a final position for the tractor, and searching for a ramp attached to the flatbed trailer. A driving path is calculated to drive the tractor from the starting position, along the ramp, and to the final position. The tractor is autonomously operated to drive along the driving path. The method may periodically detect an intermediate position of the tractor and determining if the intermediate position is located on the driving path. The driving path may be updated with a course correction to drive the tractor from the intermediate position to the final position. The tractor is stopped after arriving at the final position.

A multi-configurable load ramp for a vehicle includes an outer ramp member, an inner ramp member pivotably coupled to the outer ramp member and movable between a deployed position extending from the outer ramp member, and a folded position where the inner ramp member is disposed nestingly within outer ramp member, and a vehicle attachment device coupled to one of the inner and outer ramp members. The vehicle attachment device includes a plate member and a hook member extending therefrom, the hook member having an upper jaw and a lower jaw at least partially defining a receiving slot to receive a portion of a tailgate. In the deployed position, one of the inner and outer ramp members is configured to couple to the tailgate via the vehicle attachment device to provide a ramp surface to load and/or unload objects from a cargo area of the vehicle.

An automated cargo vehicle ramp deployment system includes a controller and a power source connected thereto, a ramp located at the existing cargo vehicle, a first automated ramp displacement mechanism for configured to selectively displace the ramp from a first position to a second position defined along a perimeter of the existing cargo vehicle while the ramp is maintained at a vertically oriented position, a second automated ramp displacement mechanism for configured to selectively displace the ramp from one of the first position and the second position to a third position, and a third automated ramp displacement mechanism for selectively adjusting a longitudinal length of the ramp while the ramp is statically disposed at a third position.

A transporter includes a frame supported on wheels, a cab mounted on a front portion of the frame, and a bed mounted on the rear portion of the frame. The bed includes deck plates and supports mounting the deck plates on the frame. At least a rear end portion of the bed is raiseable and lowerable relative to the frame. The bed is sufficiently lightweight that the transporter has a hauling capacity of at least 10,000 lbs. and a fully loaded gross vehicle weight of no more than 26,000 lbs. At least portions of the bed may be made from high strength steel (HSS) such as ASTM A1011/1011M steel having a grade of 80 or higher. A ramp, which may also be made of HSS, may be attachable to the rear of the bed and may have longitudinally extending supports and slats that may be arranged in a herringbone pattern.

A system for unloading and conveying material includes a drive over dump conveyor apparatus including a main frame with opposite lateral sides and a conveyor assembly. The system includes at least one ramp assembly mounted on one of the lateral sides and extendable to a utilization condition of the ramp assembly and retractable to a transport condition of the ramp assembly. The ramp assembly may include inboard and outboard ramp portions accordion foldable inwardly to the transport condition and foldable outwardly to the utilization condition. The system may include a movement assembly configured to move the ramp assembly between the transport and utilization conditions, actively extend the inboard ramp portion and passively extend the outboard ramp portion to the utilization position, and actively retract the inboard ramp portion and passively retract the outboard ramp portion to the transport position.

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.

A ramp apparatus of a door for a vehicle is provided. The ramp apparatus includes a door configured to open and close an interior of a vehicle, the door having an interior space, a guide unit installed in the interior space of the door, wherein the guide unit is configured to be slid to be extracted to an outside of the door or to be inserted into the door, and a ramp mechanism installed in the guide unit, wherein the ramp mechanism is configured to be rotatable, the ramp mechanism comprising a plurality of ramp panels connected to each other and rotatable with respect to each other, wherein the ramp panels are configured to be folded when being located in the interior of the door and to be unfolded when being extracted to the outside of the door by the guide unit.

Disclosed are ramps. The ramps may include a frame and a traction surface. The frame may be attachable to a mounting surface. The frame may be adjustable from a collapsed state to a deployed state. When in the collapsed state the frame may be sized to be supported by the mounting surface. The traction surface may be supported by the frame. In the n the deployed state the frame and traction surface extend from the mounting surface and provide a transition from a tailgate to a ground surface
