Heavy duty couplings

Due to our experience and know-how, we are able to offer you couplings for most European vehicles. Other vehicles can be customised by us or our service partners. Please observe or check the permissible trailer loads of your vehicle (vehicle documents, COC papers). Alternatively, if the vehicle is not included in the papers, a solution can certainly be found in consultation with the TÜV.

In order for us to be able to process your process your enquiry as quickly, correctly and without delay, it is necessary that your information is complete. Base vehicle Camper manufacturer Model/trade name Year of construction Chassis number Supplementary information such as water tank, frame extension available, etc. If any information is missing, we will contact you immediately.

It is an indication of the strength of a towbar. It is calculated according to the following formula: D = G(K) x G(A) x 9.81 G(K) + (A) If G(K) is the permissible total weight of the towing vehicle in tonnes(t) and G(A) is the total weight of the trailer, also in tonnes; e.g. a Fiat Ducato with 3.5 t permissible total weight and a trailer load of 2 t requires a coupling with a minimum D value of: D = 3.5 x 2.0 x 9.81 = 12.50 kN 3.5 + 2.0. However, the actual permissible trailer load depends on the entry under item 28 or O1 in the vehicle documents. Of all the given values, the weakest value is always decisive for approval.

In many cases, an original chassis (e.g. Fiat/Mercedes/etc.) is too short to build a camper. This is why a frame extension is usually necessary. It supports the rear garage or the entire rear area of the vehicle. Since a rear garage with, for example, a 150 kg payload has significantly lower forces than a 2,000 kg towbar or an additional load-carrier, the frame extension must be reinforced with EC-tested components to create a stable connection. For the installation of a towbar or a load-carrier, the reinforcement of the frame extension with corresponding components is mandatory.

AHK and load-carrier can be combined (use not possible at the same time). Load-carriers can still be used when changing vehicles. Only the vehicle-specific mounts are required. The electric cable set must always be ordered separately (not applicable if a towbar is available).
