What is a converter dolly?

A converter dolly is a detachable towed trailer that is used in combination with a truck tractor to haul semi-trailers. The dolly connects the semi-trailer to the tractor, allowing for greater maneuverability and a tighter turning radius than if the semi-trailer were directly connected to the tractor.

Converter dollies typically have a fifth wheel hitch at the front for connecting to the semi-trailer, and a hitch at the rear for connecting to the tractor. They are often used in double and triple trailer configurations to increase the capacity of a single truck tractor.

Converter dollies are commonly used in long-haul trucking operations and in industries where high volumes of goods need to be transported efficiently. They are subject to regulations and standards set by governing bodies to ensure safety and proper operation on the road.
