A new R 730 V8 8×8 converted to 10×8 by adding a lazy axle is the biggest Scania built for Australia. The new truck is working for Qube Bulk on its PBS Quad Road Train fleet in Western Australia’s North, in Port Hedland. The Quad sets being used are the largest on-road vehicles in Australia.
The new Scania is intended to run at masses up to 220-tonnes when further developments in the PBS combinations are made.
“We selected the Scania R 730 and 10×8 configuration to assist us achieve improved tractability and performance for PBS Quad road trains in the Pilbara,” said Todd Emmert, Director of Qube Bulk. “We have designed this truck to give us the flexibility to take advantage of payload improvements under PBS now and into the future. As it stands now, a standard Quad Road Train can pull 175-tonnes, or 200-tonnes under PBS.
“We anticipate that in the near future we should be able to raise this to 220-tonnes, once permission is granted by the relevant authority. The most important factor leading to the purchase of this vehicle was safety on the road. We have safety as a number one priority. Safety drives performance and quality outcomes.”
The quads haul bulk iron ore out of mine sites to the bulk terminal at Port Hedland. A one way trip from the mine can be as far as 450 km, so the Scanias can be expected to clock up close to 1 million km over the first 3 years of their working life on the job.
“This new prime mover will improve our productivity and efficiency and this will allow us to provide a better service to our customers, some of whom are junior miners in the iron ore export market,” said Emmert. “Boosting efficiency is critical for our clients, while for us safety is our priority.
“One of the benefits of the higher payload is ultimately a reduction in the number of truck movements on a given piece of road. Reduced interactions between cars and trucks, and having trucks with higher levels of safety will all combine to make these roads safer for all road users.
“We have gathered a degree of experience working with Scania on our other WA operations, pulling quad trailer combinations, so we know what to expect.”
The 10×8 vehicle is the prototype for future iron ore PBS Quad haulage Scania hope to deploy more widely in this market. The truck’s specification includes 4700 mm axle and 1450 mm bogie distances.
The engine meets Euro 5 with EEV enhanced environmentally friendly vehicle specification, and can run on biodiesel. The Scania fully automated Opticruise gear change system comes with Standard, Power and Off-road modes as well as Ecocruise.
The hub-reduction bogie-drive axles deliver traction, running a 4.27:1 ratio. The fifth axle is a tag unit fitted at the very rear. Braking is by drums all round using traction control, ABS/EBS, while suspension is all steel multi-leaf. The fifth wheel is a heavy-duty Jost DR38C-1 rated to 260 kN.
