On track testing of Australia’s first fully AS7502 compliant Hydrema MX20-Rail Hi-rail excavator, with final was being carried out.
Once again the Hydrema factory has produced an outstanding piece of equipment and now ADT WA can offer the MX20-Rail Hi-rail excavator as AS7502 complaint in both Hi-rail and rail guidance configurations. The Hi-rail configuration overcomes issues with guidance machines traveling through switches and level crossings, with only the rail wheels in contact with the the rail and 120mm clearance to the rubber tyres. The largest single issue overcome was to the braking systems, which has been resolved with service and park/emergency failsafe brakes on each rail wheel. Additionally, there were a number of changes to the machine that enable it to be fully compliant some of which; software control system for deployment of the rail gear, directional lighting, derailment catching devises, new design insulated rail wheels.
