SDC Trailers says it has got the first braking type approval under new UN-ECE braking regulations, covering all its semi-trailers fitted with the firm's roll stability system option. This means customers can now add the approved braking system to their trailers. The system is designed to act and cut the risk if it detects the chance of roll-over. It offers SDC's customers better trailer safety features by monitoring the trailer's movements through an on-board accelerometer and wheel speed sensors. The firm has approvals for braking systems from Haldex, Knorr Bremse and Wabco, meaning it can offer a type approved braking system with the customer's preferred EBS maker. Braking type approval will be mandatory from 2012.
