Scania XT lands for first time in Pilbara

Heavy vehicle manufacturer, Scania, has unveiled a pair of New Truck Generation XTs fitted with 40,000 litre Shermac water cart bodies for a mining operation in the Pilbara.

The NTG G 450 8x4 twin steer chassis feature side curtain roll-over airbags and with tailor-made Shermac bodies of more than double the capacity of those fitted to traditional road-going trucks, the XTs have been designed to replace mine-specific road train combinations.

Robert Taylor, Scania Australia Mining General Manager said the trucks have accumulated around 70,000 kilometres on-site in the first 12 months after being in service 24 hours a day, seven days per week.

“Our customer has had experience operating a fleet of Scania trucks on-site as service vehicles, flatbeds and technical support vehicles for the past year, and they have performed well,” he said.

“When we were discussing the replacement of the customer’s existing water carts, we suggested a more flexible solution, in the form of the NGT G 450 XT 8x4 as they could handle the higher payload of 40,000-litres for a GVM of around 66-tonnes,” said Taylor.

“The water carts are also on call 24/7 and reliability is very important to our customer. They work in an extremely harsh environment where there is a lot of dust and heat and so water cart availability is critical to the mine’s operations.”

The vehicles will be serviced on-site to maximise uptime.

Creating a new high-capacity water cart, according to Taylor, underscores Scania’s ability to configure a vehicle exactly to a client’s needs.

“One of our longer-term goals has been to be able to offer our customers the ability to replace their very high-cost capital equipment with Scania solutions that provide a greater degree of resource utilisation flexibility as well as cut their capital expenditure without compromising availability or productivity. And we are able to deliver solutions in a timelier manner as well,” he said.

Mining engineering equipment supplier Shermac, had not previously built a water cart of 40,000 litres capacity for a four-axle on-road application according to the company’s Sales Manager Jim Ray.

“Our client was looking for a new solution to its water cart requirements and wanted to combine the flexibility of a road-going truck with water capacity approaching that of heavy mining gear, in order to maximise availability and ease of maintenance,” he said.

“Scania has shown us that it has a lot of experience working globally with mining partners, and they said they were confident that the 8x4 chassis would be suitable for this payload, having seen 66-tonne payloads used widely in tipper configurations in South American and Indonesian mine sites.”

Shermac’s water carts are custom designed and tested to ensure optimum weight distribution and performance for the most challenging conditions.

“With liquid loads you do get high dynamic forces, but our Roadserve 2000 model water cart is well baffled and on-site speeds will be low and there are few inclines, allowing the vehicles to do their jobs reliably,” said Ray.

“Scania also has a lower centre of gravity compared with the previous solution, which also aids stability and safety,” he said.

Protective grilles for the LED headlights, a fold-down bumper-mounted step to allow safe access for on-site windscreen cleaning and a 40-tonne capacity tow point are among the defining features of the Scania NTG XT range.

With a gross vehicle mass of 66-tonnes distributed on 12-tonne front axles and two 21-tonne rear drive axles, the G 450 B8x4HZ chassis has been spec’d to a 5950 mm axle distance.

The 450 hp 13.0-litre six-cylinder in-line engine drives through a Scania Opticruise automated gearchange and GRSO935R transmission, with specific Off-Road mode built into the management system. A hydraulic Retarder system, the latest and highest output from Scania, is fitted to preserve the service brake linings on the drum brakes, which are backed by ABS.

Scania makes the claim that with its steering-wheel mounted airbag in addition to driver and passenger side curtain airbags, the Scania XT is the “world’s safest truck for extra-tough working environments” it said in a statement.
