The new Ringfeder generation

A new generation providing unparalleled reliability, product life and total cost of ownership.

The new trailer couplings are more compact yet sturdier. Exposed parts are reinforced while service and maintenance have been made easier. In addition, there are new features for convenience, safety, and time-saving.

Rear underrun protection devices


From 1 September 2021 the legislation R58 rev. 3 applies to all new registered vehicles.

The permissible dimensions have been changed and the requirements for impact resistance have been sharply raised. All components in the rear underrun protection must be R58.03 certified. Thus, it is not permitted to mix components from different manufacturers, not even if the components are individually certified.
