Convertor dolly is described as an auxiliary undercarriage assembly consisting of a chassis, fifth Wheel and towbar used to convert a semitrailer or a container chassis to a full trailer.
A converter dolly, also known as a converter, is a type of trailer attachment used in the transportation industry. It is typically used to connect a semi-trailer to a truck tractor, allowing for the transport of heavy or oversized loads. The converter dolly is essentially a short trailer with a fifth wheel coupling at the front and a pintle hitch at the rear. It is designed to distribute the weight of the semi-trailer between the truck tractor and the dolly, providing stability and maneuverability during transportation. Converter dollies are commonly used in applications such as road transport, intermodal shipping, and container hauling.
