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.
