The
VOLK Electric Tow Tractor EFZ 40 N is serially equipped with a Rockinger 230 bolt coupling which is usually sufficient for maneuvering jobs.
During hard daily use as a towing vehicle, however, it is advisable to use a self-closing automatic coupling such as the Rockinger 244 D coupling. This makes hitching easier because the driver only has to back the vehicle up to
the trailer – the coupling closes and locks automatically at the same time. In addition an automatic coupling is very safe because nobody has to step between the vehicles during hitching.
The Rockinger 244 D model is
suitable for towing eyes with an inside diameter of 35 mm. The coupling height can be variably adjusted to your individual requirements.
