Airtec offers transport operators new options for type-approved OBM system

17 February 2020

Transport Certification Australia has today announced Airtec Corporation’s (Airtec) new option for transport operators wanting to benefit from its existing type-approved OBM system.

Airtec is a leading supplier and manufacturer of digital tyre inflation and truck scales and mass management systems around the world. Its 89AXM Series OBM system obtained type-approval in April 2019.

This same OBM system can now be used with an alternate Mass Sensor Unit (MSU) – the part of the OBM system used to measure axle mass loads – offering choice to transport operators.

The OBM system and new MSU model are designed to work together – details listed below:

89AXL400 Series

David Hewett, Managing Director of Airtec Corporation, said, “The 89AXL400 Series is a smart truck scale that is cheaper and easy to use, while still offering the benefits of type-approval.

“By using wireless technology between trailers and prime movers, we’ve been able to introduce greater flexibility for transport operators, and reduce set-up costs.

“Airtec’s experience within the transportation sector, and its expertise in developing on-board mass and inflation systems for over 20 years, contributes to a strong and focused mass management solution,” said Mr Hewett.

There are three categories of type-approved OBM systems (categories A, B and C) which meet the needs of different stakeholders. Category A OBM systems electronically display mass information to drivers or loaders.

All categories of type-approval are subject to an assessment of the performance-based requirements contained in the OBM System Functional and Technical Specification.

A list of type-approved OBM systems is available on the TCA website.
