NZR NZR Patented D-Train Hitching System View from the Top Down – The “Rigid” Connection • Tractor has just backed into the kingpin of the trailer and by nudging forward has already exposed the “B-Train” for connection to the second trailer ( a single axle trailer and an “A-Train converter dolly connection is optional) • Have ignored the landing gear for simplicity of demonstration • The tractor-facing end of the trailer bogie is equipped with a unique after-frame pocket assembly which has entrance guides on each side. The after-frame of the tractor will typically tuck inside the trailer D-Train pocket about 11 – 12 inches. This depth is managed by allowing the fifth wheel to be pushed or pulled to complete a proper connection.
