Couple tractor and first semitrailer as described earlier: A converter gear or dolly is a coupling device of one or two axles and a fifth wheel by which a semitrailer can be coupled to the rear of a tractor-trailer combination forming a double bottom rig.
Connect the Converter Dolly to the Rear Trailer. 1  Make sure the trailer brakes are locked and/or the wheels chocked. 2  Make sure the trailer height is correct. 3  Back the converter dolly under the rear trailer.  Raise the landing gear slightly off the ground to prevent damage if the trailer moves.
