Abstract
A powered converter trolley for movement and attachment of trailers is provided. The trolley comprises a conventional converter trolley having a drawbar. The trolley has a power supply and operates as a towing device. The trolley connects to a freight trailer and can be raised or lowered from a stored position to a ground-engaging, working position. Alternatively, the wheels of the trolley may be powered for providing motion to the trolley. The trolley further comprises several attachment devices for securing the trolley to an intermodal railcar, including alternative hydraulic, mechanical, and electrically-powered tie down devices. A trolley movable along a railcar is provided for securing the trolley or trailer to the railcar and includes a hitch component for selectively interconnecting to a hitch component on the trolley or trailer.
