Further testing and simulation of hay bale loading on semi-trailers
The project focussed on the safety implications of possible changes to hay and straw loading regulations in terms of the NRTC/Austroads Performance-Based Standards for heavy vehicles (PBS). The outcomes of the study showed that hay/straw industry vehicle loads are safe when properly restrained, and practices are currently unduly restricted by inconsistent loading rules. It was recommended that hay loading rules could be made uniform by applying a general hay loading rule across all States allowing the operation of complying hay trucks to a maximum overall height of 4.6 metres and a maximum overall width of 3.0 metres, provided axle mass limits were not exceeded. However, the poorer stability performance of tandem axle trailers in comparison with their triaxle counterparts suggested that hay trucks incorporating tandem axle trailers should be limited to an overall height of 4.3 metres. Regarding load restraint, it was found that there are small but worthwhile benefits to be achieved by using more effective load restraint methods such as double-strapping or "double-dogging" of single straps.
