Getting Tippers Right

When it comes to the question of getting tippers right, the National Heavy Vehicle Regulator wants the trailer manufacturers to make the regulations work both for them and their customers. The Heavy Vehicle Industry Association has been asked by the NHVR to lead the development of a new VSB6 modification code that covers the design of tipper bodies.


Getting Tippers Right


Following the release of Vehicle Standards Bulletin 6 (VSB6) Version 3 in July 2017, both HVIA and the NHVR received feedback from tipper body manufacturers revealing confusion over the best way to achieve compliance.


“Some manufacturers raised concerns that some tippers would require re-design of tipper body systems in order to meet Australian Standards, required under VSB6,” said Peter Austin, NHVR Vehicle Safety and Performance Manager. “The NHVR recently reviewed the requirements of the relevant parts of the Australian Standard and agreed that the design of tipping systems involves a reasonable amount of engineer level work.


“Rather than requiring an engineer to assess every tipper body installation, the NHVR is proposing that a two stage design-modification approach be adopted. We’ve asked Heavy Vehicle Industry Australia (HVIA) to provide a draft of the code in consultation with industry.”


Australian Standard AS1418.8 section 4 sets the requirements for tip truck hoisting systems (tipper body systems). These standards have been adopted as part of VSB6 Version 3.


To be compliant with the standards, re-design of tipper body system components may be necessary in some cases.


“The NHVR recognised the amount of engineer-level work that designing tipping systems requires, and that clearer design guidance is required than outlined in the current VSB6 Section J ” said Paul Caus, HVIA Chief Technical Officer. “Rather than requiring an engineer to assess every tipper body installation, the NHVR is proposing a two stage design-modification approach be adopted. Over the next few weeks HVIA will confer with members who design, manufacture and certify tippers towards creating a working group for the project.”

Todd Hacking, HVIA CEO, welcomed the opportunity to draft the modification code.


“This has been an issue raised with us by our members and we look forward to working with them to find a solution,” said Hacking. ”HVIA has a proud history of working with Government to find technical solutions, including drafting numerous sections of VSB6 30 years ago.”
