Frequently asked questions

  • Your coupling system specifications can be found directly, on the label bonded onto the system, or in our catalogue.

  • The value D (expressed in kN), for a coupling system, is the maximum horizontal dynamic force generated by an articulated bar rig.

  • The value D (expressed in kN), for a coupling system, is the maximum horizontal dynamic force generated by a rig with central axles.

  • D = [(gross weight of trailer x max. loaded weight of carrier) / (gross weight of trailer x max. loaded weight of carrier)] x 9.81

  • Dc = [(gross weight of trailer x max. loaded weight of carrier) / (gross weight of trailer x max. loaded weight of carrier)] x 9.81

  • The value S (expressed in kg), for a coupling system, is the max. acceptable vertical static load. When preparing a load plan, this value must never be exceeded.

  • The value V (expressed in kN), for a coupling system, is the maximum acceptable vertical dynamic force generated by a rig with a central-axle trailer.

  • V = [gross weight of trailer x length of trailer platform x length of trailer platform x 2.4 (for a vehicle with mechanical suspension) or 1.8 (for a vehicle with pneumatic suspension)] / [total length from the ring to the trailer axle centre x total length from the ring to the trailer axle centre]

  • The marking ECE R55 indicates that the system is approved in accordance with European Regulation R55. This regulation defines the requirements to be met by coupling systems and mechanical parts, to be considered internationally compatible.

  • The OF N° on a Pommier product is the manufacturing batch number. It comprises the year and week of manufacture, and the number of products manufactured.

  • The tightening torque values for your coupling are shown directly on the label bonded on the coupling, or in the coupling installation documentation.

  • A Spare Parts catalogue is available on our Web site, in PDF format. It will enable you to find all the spare parts available for most POMMIER products.

  • Yes, couplings can be painted. However, take care to ensure that the mechanisms remain functional and that the identity plate is still legible.

  • If the coupling system is approved R55, it is acknowledged as valid in all European Union countries. You can therefore use it everywhere in Europe.
