  • Patent number: 8348589
    Abstract: A Universal Folding Boom Trailer for transporting multiple vehicles provides a safe and legal manner for towing. The trailer includes a winch for loading and unloading the towed vehicles and can act alone as a crane if desired. Further, this trailer arrangement backs up like a conventional trailer. The Universal Folding Boom Trailer provides a means for a driver to haul multiple vehicles in both directions. The driver is able to attach the trailer to a personal fifth wheel and tow any type of unit: a fifth wheel trailer, a ball hitch trailer, or a gooseneck, among others—instead of dead-heading.
