Amended Procedures and Criteria Around Roller Brake Testing

Amended Procedures and Criteria Around Roller Brake Testing

Diesel Workshop looks for roller brake testing feedback. The amended procedures and criteria around roller brake testing (RBT) of trucks is settled and the industry can move on. The National Heavy Vehicle Regulator went through an exhaustive process to get the testing procedure right and consistent. 

Diesel Workshop has asked the suppliers of roller brake testing equipment to give their comments regarding the changes:

Levanta Look at the Changes in Roller Brake Testing

Levanta Workshop Solutions applauds the NHVR for consulting through the working group and deciding on a new testing procedure. The working group is something we have been part of since the start and we will continue our involvement. 

This is to ensure not only brake safety, but also ensuring our clients have the means to be able to meet the criteria set by the regulator. We have the ability to easily alter our software to ensure all machines we have supplied nationally confirm to ensure full compliance is achieved. We have already been very active in carrying out software upgrades. Our software has full functionality to adopt to the new rules and can even be done remotely as things change.

MAHA examine the NHVR Roller Brake Testing Changes 

With NHVR Roller Brake testing procedure changes upon us, there is much confusion and are many untruths or speculation around the heavy vehicle industry. To keep it relatively simple and to the point, technology in truck and trailer braking is continuously improving and evolving. A national procedure had to be written to allow for brake testing on lightly laden axle with reactive suspensions.

The main changes which the NHVR / RMS have now agreed to are to show both static & dynamic deceleration rates and axle weights:

  1. Static Deceleration rate: the roller brake tester measures the weight before the brake test with the rollers stationary  
  2. Dynamic Deceleration rate: the roller brake tester measures the weight during the brake test with the rollers rotating.

The honeymoon period is over as of May 1st 2018 when the braking limit will be raised to a minimum of 45 per cent deceleration. This also opens the window for inspectors to make a more informed decision based on heavy vehicle conditions & configurations. Where a fine margin is found the inspector now has the opportunity to allow tolerance or retest the axle set where applicable. 

We at MAHA, through our Eurosystem software can easily adapt to these changes and future-proof all our customers. As prescribed by the NHVR for the stage 1 changes, MAHA will roll out the changes to the various testing agencies in the coming 3 months and all our customers over service & calibration time throughout the year to meet the NHVR deadlines.

NAES and Jevol are making new NHVR Roller Brake Test Requirements wireless!

Recent changes to NHVR requirements have seen some urgent updates required for Roller Brake Testers in workshops and testing stations around Australia. Changes are now required for people using the tester in the areas of compliance or enforcement and during an inspection of a heavy vehicle.

Some older machines that have been around for many years are now requiring reprogramming and modifications to keep up with the changes recently released. For Jevol and NAES these changes are already underway and are as simple as having an internet connection.

Existing and all new machines in both in-ground and mobile versions already possess the Wifi connectivity to remotely make the changes directly from the factory or service technicians. This technology allows for program updates and even fault diagnosis saving hours and most importantly dollars off the costs of running the Jevol Roller Brake Testing System.

Sometimes with technological advances it becomes necessary to update older outdated equipment as the costs associated with maintenance and modification outweigh its value to the business. If you would like to update some existing equipment to see how easy the many changes can be incorporated into a machine to benefit your business visit www.naes.com.au today or email info@naes.com.au .

VIS-Check Roller Brake Tester

Dan Cleary of Nepean Transport Equipment manufacturers of the VIS-Check Roller Brake Tester reports that; Nepean Transport Equipment says he has been working closely with the Australian Trucking Association (ATA) as an active member of the Industry Technical Council (ITC) to lobby changes to the procedure. 

We originally approached the NHVR at the Brisbane truck show in 2015 about the issues we felt existed at the time, but thing were slow moving. I raised the issue with the ATA and we soon found a strong technical voice for change. I think more suppliers should engage actively with ATA’s ITC. Hendrickson supplied data out of the USA, that supported the reactive nature of trailing arms suspension being tested on Roller Brake Testers as an issue.

Nepean is fortunate to supply equipment into the USA and is only one of three approved vendors for the Federal Motor Carriers Administration. We consider this a very relevant point of difference as the USA application and method is complimentary to Australia’s new direction, whereas they are testing using the Dynamic Method over mobile equipment roadside. More importantly Hendrickson found the problem and the USA moved from Static to Dynamic relatively quickly.

 

Amended Procedures and Criteria Around Roller Brake Testing

Nepean has extensive experience in the use of Dynamic Weight when calculating roller brake testing results, and most of the software code required by the NHVR has already be tested by us in similar USA applications. This method along with customised software has let us put in place many of the software feature that eliminate many of the false results. 

All VIS-Check roller brake testers in use in Australia today can be upgraded with no redundancies in the field. We are proud to continue to supply equipment that is upgradable and has a proven useful life. We supply equipment to every enforcement body in every state in Australia, and service fleets and repairers Australia wide. We are specifically looking forward to working with the industry with a very fair and level playing field as far as roller brake testing is concerned.
