Abstract: The present invention is a structural beam having at least one composite core within a hollow beam of metal or polymeric material, i.e. a jacket, and a layer of elastomeric material between the composite core and the inner walls of the metal or polymeric jacket. This structural beam also may be fitted with brackets or holes at its ends and points along its length to allow attachment to other structural elements. The present beam provides a synergism between the properties of its composite core and the metal or polymeric jacket, and is particularly useful where a high strength to weight ratio is required.

Abstract: The Super Beam is comprised of any structural medium hollowed out to receive any or all of a carbon composite core. Using the structural medium for the purpose of attachment to adjacent structures. This allows the carbon composite core which is the primary strength of the Super Beam not to be altered by any holes [drilled, nailed or screwed, etc.] or heat transfer by welding. After all engineered requirements for adjacent attachments are made to the hollowed structural medium the carbon composite core can be inserted into the hollowed structured medium. This now allows the Super Beam to be attached to adjacent structures without compromising the rated strength of the carbon composite core.

Abstract: A detachable gooseneck trailer [12] having a gooseneck [11] and a detachable trailer deck [10] utilizes a trailer attachment assembly [13] to draw the trailer deck [10] toward the gooseneck [11] during attachment. The attachment assembly [13] includes a rotary trailer lift arm [14] powered by an electric motor [45] which attaches itself to the trailer lift pin [16] which will be raised and drawn towards the gooseneck [13] by the rotation movement of the trailer lift arm [14] to a level 1 position shown in FIG. 1 Position 2. Once in position the lock bars [15] in the gooseneck [13] powered by an air cylinder [16] and a rotating spread screw [17] will enter the trailer lockbox [18] the spread screw [17] will spread the lock bars [15] inside the trailer lockbox [18] and proceed to screw into a threaded block [19] attached to trailer [10] locking the trailer [10] to the gooseneck [13].
