Trailer load increase and total pull weight test

Is your vehicle capable of pulling more than approved by the manufacturer? It is possible to increase the trailer load by simply making some small technical changes.

In many cases, the trailer load or the total pull weight is restricted to a certain value by manufacturer-specific standards. The reason for this can be technical or strategic.

We have a standardised testing programme which we can use to enable approval for an increased trailer load or total pull weight in line with the European standard ECE-R 55.


We can carry out tests for the increased D-value and the tongue and vertical load during the process of designing a new or reinforced tow bar or converting a vehicle to an articulated lorry.
