Air brake systems

Trailer hitches and adapter plates

In addition to the standard air brake systems, Tietjen also offers trailer hitch systems for retrofitting. Solutions have been developed for the most diverse types:

  • With trailer hitch types, e.g.
    • Ø38 mm or Ø50 mm bolts
    • Automatic or fixed couplings
    • K80 coupling
  • With adapter plate construction / add-on plates for the rear weight
  • Without adapter plate construction / add-on plates for the rear weight
  • With or without height adjustment in the tow-bar
  • With two different coupling heights

To ensure that the designed construction can withstand the loads, we perform an FEM (finite element method) analysis. This allows us to examine the strengths and deformations in advance and make further adjustments if necessary.


We will gladly create an individual proposal for you. Simply download, complete and return the "Trailer hitch data sheet" below.

The scope of supply can vary greatly and is usually decided on a customer-specific basis, as the engineering can be very different depending on the type of vehicle, vehicle body and customer requirements. An exemplary scope of supply would be:

  • Trailer hitch with flange, e.g.:
    • Ø50 mm or Ø38 mm bolts
    • 50 mm ball head coupling
    • K80 ball head coupling
  • Add-on plates for rear weight including fastening material
  • Options:
    • Light socket and ABS/EBS plug socket incl. holder and cabling
    • Voltage transformer
    • Duo-Matic quick-coupling
