The Objective
Road access for 194.5 tonne 60m Super Quad
The Process
The Bruce Rock Engineering (BRE) bolt in tow eye arched A-Frame drawbar has been analysed for strength and fatigue by Finite Element Analysis (FEA) according to Australian Design Rule (ADR) 62/02 requirements.
After undergoing rigorous safety assessments to ensure that they were safe on public roads, the vehicles were approved for trial in mid-2015 by Western Australia’s Transport Minister Dean Nalder who announced that:
“These vehicles are known as Super Quads and we have committed to an Australian-first trial of these roads trains to operate in the Pilbara region…Even though they are longer, these are state-of-the-art vehicles with improved safety and superior handling compared to the standard 53.5m road trains, the longest currently allowed on our roads”.
The Results
- Help Main Roads WA make an access determination with respect to a proposed 194.5 tonne 60.0 metre Super Quad Train combination (tri-axle trailers).
- Help introduce the 60.0 metre Super Quad Train combination with improved safety and superior handling system in WA.
- Facilitate the operation of the Australian-first trial of Super Quad Road trains in the Pilbara region.
- Help Bruce Rock Engineering design and implement the A-Frame Drawbar into the Super Quad road train combination.
