KONEXO EVO - Coupling with guiding ramp

Frequently asked questions

• Where can I find the specifications of my coupling system?

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

• On my coupling system, what does the value D mean?

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

• On my coupling system, what does the value Dc mean?

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

• How can I compute the value D for my rig?

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

• How can I compute the value Dc for my rig?

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

• On my coupling system, what does the value S mean?

  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.

• On my coupling system, what does the value V mean?

  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.

• How can I compute the value V for my rig?

  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]

• What does BNA mean?

  The initials BNA mean “Bureau de Normalisation de l’Automobile” (French standards authority for couplings in France).

• What is the difference between a BNA hook and a DIN hook?

  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)

• Can a BNA hook be used with a DIN ring and vice-versa?

  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.

• On my Pommier coupling system, what does the OF N° mean?

  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.

• Where can I find the tightening torque value for the installation of my coupling?

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

• Where can I find spare parts for my coupling system?

  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.

• What is the part number of the pin repair kit for my KONEXO hook?

  The part number of the KONEXO hook pin repair kit is: 2944034

• Is it possible to upgrade my KONEXO manual hook to a KONEXO automatic hook?

  No, unfortunately a manual hook cannot be converted to an automatic hook.

• Can my coupling be painted?

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

• If I purchase my coupling in France, can it be used in other countries?

  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.

• Can a play compensation system be installed on my KONEXO hook?

  If your KONEXO hook wasn’t initially equipped with a play compensation system, then unfortunately it cannot be retrofitted without work at our factory.

• What do the markings G145 and G150 mean on my hook?

  G145 and G150 are the between centres spacing for the drilled hook holes. G145 means a drilling spacing of 140x80 mm, and G150 means a drilling spacing of 160x100 mm.
