Abstract:
An overhead door assembly configured to be coupled to a storage container, such as a truck trailer, including an overhead door including a plurality of door panels hingedly coupled to one another and a bottom roller assembly coupled to a bottom panel of the door. The bottom roller assembly includes a hinge and a roller coupled to a lower hinge plate of the hinge. The roller includes a shaft and a roller wheel coupled to one end of the shaft. Illustratively, the lower hinge plate and the roller thereon are configured to pivot about a pivot axis of the hinge relative to the bottom panel of the door between a first position generally adjacent the bottom panel of the door and a second position spaced-apart from the bottom panel of the door.

Abstract:
A semi-trailer for transporting circular objects may include a coupler assembly configured to be connected to a towing vehicle, a rear frame member, a pair of side rails joined at rear ends thereof by the rear frame member and at front ends thereof by the coupler assembly, a rear wheel and axle assembly mounted to the side rails between the front and rear ends thereof and at least one transportation well mounted to and between the side rails. The at least one transportation well may extend below the side rails. The at least one transportation well is configured to receive and hold therein while being transported by the semi-trailer at least one circular object.
Abstract:
A side skirt system for reducing drag on a trailer includes a side skirt wall configured to be coupled to one side of the trailer to extend below a side wall of the trailer along a length of the trailer. A mounting bracket assembly of the system is coupled to the side skirt wall and is configured to be coupled to a floor assembly of the trailer. The mounting bracket assembly is configured to tilt laterally outwardly and laterally inwardly with respect to a generally vertical axis parallel to the side wall of the trailer. A side underride cable system configured to be coupled to a trailer includes a front mounting bracket assembly configured to be coupled to the trailer, and a rear mounting bracket assembly configured to be coupled to the trailer at a location spaced-apart from the front mounting racket assembly.
