Abstract: A method for shipping a retractable cover system include pre-assembling the cover system to include the flexible cover and enough components to support the cover on guide rails mounted to a trailer or other transport vehicle. At least two pre-assembled cover systems are compressed along their length and then loaded sequentially onto the guide rails of the same trailer. In certain embodiments, four compressed partially pre-assembled cover systems are loaded onto a single trailer. The trailer is then transported to one or more customer sites where one or more of the compressed cover systems are unloaded. The cover systems may be only partially pre-assembled, with the remaining components placed on the trailer within the compressed cover system when it is loaded on the trailer. The cover systems may be maintained in their compressed state by a tension element or tensioned apron wrapped around the compressed cover system.

Abstract: A bow structure for supporting a flexible cover or tarpaulin includes an intermediate bow and an uplift bow arrangement supported on the intermediate bow. The uplift bow arrangement includes a U-shaped bow supported on compression springs. The compression springs bias the bow along the axis of the bow arms, thereby exerting a generally upward force on the inside of the tarp.

Abstract: A bulkhead adapter for a DOT rated bulkhead installed on a flatbed vehicle includes a pair of wings attached one to each side of the bulkhead. Each wing includes a vertical member attached to the side panel of the bulkhead and an upper member extending from the upper end of the vertical member. Each upper member is configured for attachment to the corner of the upper panel of the bulkhead, which may be curved or rounded. A compressible seal is disposed between each wing and the bulkhead. The wings are attached with suitable fasteners such as bolts or screws. The wings are preferably made of metal such as steel or aluminum. The adapter widens the bulkhead to allow for the installation of a flexible cover system such as the Conestoga® system to cover the bed of the vehicle to protect the cargo space from inclement weather and road debris.
