TCA type-approves Knorr-Bremse OBM system

29 July 2021

Transport Certification Australia today announced Knorr-Bremse Australia Pty Ltd has obtained type-approval for an On-board Mass (OBM) system.

The Knorr-Bremse Group is a world-leading manufacturer of braking systems. Based in Munich, Germany, Knorr-Bremse has a long footprint in Australia.

Gareth Lawless, Trailer Business Manager of Knorr-Bremse Australia, said, “For more than 115 years, we have pioneered to deliver cutting-edge and globally-successful brake control systems for both rail and commercial vehicles.

“Innovation is one of our key core values and forms part of our company’s DNA, so attaining TCA type-approval of our OBM system is yet another significant milestone for our company.

“For our Australian technical team that developed our OBM system, it is a wonderful achievement.”

Gareth added, “We are now focussing our efforts on ensuring the Knorr-Bremse OBM system is available for our clients by the end of this year.”

On-board mass (OBM) systems measure the mass of axle groups and calculate the gross vehicle mass of a vehicle.

Type-approval involves the assessment of OBM system ‘types’ against the performance-based requirements contained in the OBM System Functional and Technical Specification.

Details of the Knorr-Bremse OBM system type-approved by TCA are listed below:
