The present invention relates generally to the field of trailers. More specifically, the present invention relates to a paddleboard trailer device that is comprised of a top surface further comprised of at least one board receiving structure, at least one cooler box, at least one main storage box, and a rear surface with at least one internal compartment. The base of the device further preferably resembles a utility trailer and is durable and rigid such that it can support the weight of multiple paddleboards or surfboards and other heavy objects. The device is also comprised of a board receiving structure that securely and efficiently organizes the boards to prevent damage and enhance accessibility. In this manner, the device can be attached to any vehicle with a trailer hitch, such that a large group of people can easily travel to a water location in a minimal number of vehicles.

Disclosed herein is a retractable cargo box assembly for a cargo bed of a vehicle. The retractable cargo box assembly includes a cargo box. The cargo box includes a base extending laterally between a first side and a second side, and extending longitudinally between a front end and a rear end. A linear wheel assembly is mounted to the base. The linear wheel assembly includes a plurality of rollers aligned in a linear arrangement between the front end and the rear end of the base. The rollers are configured to rotatably support the cargo box on the cargo bed of the vehicle between a retracted position and an extended position.

A vehicle insert with refrigerated and non refrigerated sections for facilitating product distribution is described which uses a pair of frames defining a vertical member and one or more horizontal members. Several shelves with rollers are attached to the frames. The shelves define a sloped area wherein the lowest point on the shelves is located at a product retrieval point and wherein said insert is wheeled into a vehicle already loaded with product to be delivered.

A wheel dolly for lifting and transporting a flat tire attached to an aircraft is comprised of a frame assembly having first and second laterally spaced frame members that are pivotally coupled to each other at one side. A ram is interposed between the first and second frame members. A pair of tire lifting and support assemblies are pivotally coupled the frame assembly. A plurality of wheels is coupled to the frame assembly to allow the frame assembly to roll in any direction.

Systems, methods, and apparatus for an aircraft cargo handling system articulating ball mat are disclosed. In one or more embodiments, a method for transferring cargo across a stepped threshold and into a sloped compartment involves moving the cargo across the stepped threshold and onto a ball mat located within the sloped compartment, where the ball mat is configured in a substantially horizontal position. In one or more embodiments, the surface of the ball mat comprises at least one conveyance device (e.g., at least one roller ball and/or at least one caster). The method further involves configuring the ball mat in a sloped position. Further, the method involves moving the cargo off the ball mat and into the sloped compartment.

A container deck of a trailer includes a front mounting floor, a central elevating floor, a rear mounting floor and a rear elevating floor, the central elevating floor is capable of loading and unloading the air container from the left or right side of the trailer vehicle body, the rear elevating floor is capable of loading and unloading the air container from any of the left and right sides and rear end, the front and rear mounting floors are provided with a roller conveyor for movably placing the container and a roller conveyor and a fixed side guide for slidably engaged the container, the central elevating floor is rotatable, the rear elevating floor includes a turntable and a ball conveyor, the central elevating floor and the rear elevating floor are capable to move up and down a single container.
