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 initials BNA mean “Bureau de Normalisation de l’Automobile” (French standards authority for couplings in France).
  • A BNA hook is a fixed hook with a pin Ø 68 mm. A DIN hook is a rotary hook with a pin Ø 40 mm or 50 mm)
  • No, the two products are not compatible. If you have a BNA hook, it can only be coupled to a BNA ring. And similarly for a DIN hook.
  • 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.
