The present invention seeks to overcome difficulties associated with existing road trains by providing for a powered dolly that can support a separate source of motive power to that of the prime mover, provide sufficient cooling therefor, and be able to be controlled whilst coupled to a trailer, whether that trailer be powered or un-powered. Such a powered dolly also enables the use of rear axle, belly dump trailers. The present invention also provides that such a power dolly may be used in a multicombination vehicle which may include multiple trailers both un-powered and powered, and multiple dollies both powered and un-powered, for use on public and/or private road networks. |
