Nexus Sliding Bridge
Using a rail attached free flowing Distribution Plate the Nexus Sliding Bridge allows the free movement of the vehicle services across the rear of the cab; reducing the amount of stretch required when in full articulation. The driver has the advantage of being able to move the services to carry out connection & disconnection of the trailer.
If tractor unit and trailer are fitted with similar systems it is now possible to couple from ground level, see the Nexus Trailer Interface.
