  7. Coupling Compatibility

When adding Vehicle Units, the couplings must be compatible.

For example, to add a Vehicle Unit to one that has a fifth wheel, the incoming Vehicle Unit should have a kingpin at the front.

For Vehicle Units that usually have A Couplings, they come in with an 'Empty' Coupling. When adding a Vehicle Unit then the Coupling is automatically swapped to a Pin Coupling by default.

For Vehicle Units with Fifth Wheels, they will always be present.

If you want to put a Coupling on the rear most Vehicle Unit then the rear Coupling can be swapped like any other Vehicle Component.

We also have different types of A Couplings and drawbar connection points such as Ball Couplings, Receivers, Lunette Rings, Drawbar Eyes. These also need to be compatible:

  • Pin <-> Drawbar Eye
  • Fifth Wheel <-> King Pin
  • Pintle Hook <-> Lunette Ring
  • Ball <-> Receiver
