In 2004, JOST took over the long-established company Regensburger Zuggabel. The company, formerly known as Grau, has been developing and producing drawbars for nearly 80 years. These products are sold under the ROCKINGER brand today.
Drawbars are the connection between the tractor and the steerable drawbar trailer. They are designed to be mounted on a pivot support and are subject to the highest safety requirements. Drawbars may only be operated with the intended towing hitches that are approved for the respective towing eyes.
