Modena, October 2019 – The new RVBR (EU 2015/68) standard for braking systems of agricultural machines in the European territory requires them to be equipped with double line braking systems. The first line, the Control Line (CL), supplies the pressure and the quantity of oil necessary to actuate the trailer braking system. The second line, the Supplementary Line (SL), permanently supplies a set pressure between 15 and 35 bar, which keeps the automatic emergency brake inoperative. If the pressure in the SL pipe drops below a minimum value (which means a failure of the tractor or, in the worst cases, a disconnection of the pipes caused by a crash), the braking system automatically applies the emergency brake of the trailer to stop it.
