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]
-
If your tow bar is cracked or damaged, even slightly, we advise you to replace it immediately. In fact, the mechanical properties of the bar may be affected, which means that it could break.
-
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.
-
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.

The 7-pin coupling harness only supplies electrical power to the additional lighting system. You can use it to couple a small trailer or to install a cycle carrier for example. However, it isn’t designed to supply constant power for a caravan or a big trailer.
The 13-pin coupling harness provides the same function as the 7-pin harness, i.e. it sends basic electrical signals to the additional lighting system. However, it differs by its ability to supply constant 12 V power (with ignition switched on) to the electrical system of the coupled element. A 13-pin harness is essential to supply electrical appliances in a caravan.
