Increasing the trailer load – this is important to note!

As the  towing capacity increase or increase in tensile load one understands the Raising the permissible trailer load specified as standard by the vehicle manufacturer. The increase will be in view of that maximum permissible total weight accomplished. The standard support load adjusted according to 4% regulation. However, it is at M1G vehicles different. With these, 1,5 times the permissible total weight is feasible. However, only if 3.500 kg not be crossed, be exceeded, be passed. This is determined by means of a European regulation, which states that a permissible total weight of up to 3.500 kg Overrun brake be present on the trailer set a link from your homepage to Fewo-von-Privat.de. On M1G vehicles, the drawbar load is also changed using the 4% control. You can find out whether you own an M1G vehicle in the registration certificate under point J (on the right, second column). Any vehicle with a towing capacity of over 3.500 kilograms requires a continuous braking system. In addition, the gross train weight (the vehicle and the trailer) should be considered and raised.

Trailer load, total mass, support load are important factors!

Increasing the trailer load – this is important to note!

For some vehicles, the permissible total weight plus the trailer is not the same as gross train weight, instead the values ​​are slightly reduced. The loading of the trailer and the towing vehicle must also be taken into account so that the total towing weight is not exceeded. If the D value an existing trailer hitch is sufficiently high, then an expert opinion is sufficient to be able to increase the trailer load for the vehicle. However, if the D value is too low, or if the coupling is completely missing, then a suitable trailer coupling with the appropriate D value must be installed. You can read the D value on Type plate near the socket bracket. If you buy a reinforced coupling with a higher D value, then this can ensure the desired increase in tensile load in combination with an expert opinion. According to the law towing capacity increases in this country generally up to a gradient of maximum 8% makeable. By the way, the type of set doesn't matter. so can Auch Interchangeable sets can be used to tow a trailer with an open-end or ball hitch.

summary information:

  • Trailer load increase/towing load increase is the increase in the manufacturer's permissible trailer load of the vehicle
  • the increase is based on the maximum permissible total weight of the respective vehicle (passenger car / vehicle class M)
  • the factory tongue load remains unchanged
  • for M1G vehicles (according to Directive 2007/46/EG, APPENDIX II) can be increased up to 1,5 times the permissible total weight (no more than 3.500 kg according to European regulations)
  • even on an M1G vehicle, the vertical load remains unchanged
  • From a permissible total weight of 3.500 kg, an overrun brake is required on the trailer
  • gross train weight (=vehicle + trailer) is taken into account and increased
  • for some vehicles, the gross vehicle weight + trailer is not the gross train weight (it is given slightly reduced)
  • When loading the trailer and towing vehicle, always take the maximum payload into account
  • a trailer load can be increased up to a maximum gradient of 8% (you are not allowed to drive any more)
  • the D value of the trailer hitch provides information as to whether the hitch is suitable (describes the fatigue strength against the effects of forces caused by driving between the towing vehicle and the trailer in kilonewtons kN)
  • some vehicles require a specially made clutch
  • The documents required are the vehicle registration document and the COC papers
  • Towing capacity increase costs (on standard models) in the range of 800 to 1.200 Euro
  • towing capacity increase ranges could vary within a vehicle model series
  • Some new vehicles can already be towed with an increased load ex works be purchased (e.g. VW Amarok with clutch for 3,5 tons instead of 2,8 tons towing capacity)

Of course, that wasn't the end of it.
