Bis-designed Rexx goes the distance at Granny Smith - Mining Australia

Wednesday, 12 June 2019

A "game-changing" haul truck designed and built by Bis has conquered another trial at Gold Fields Granny Smith mine in Western Australia.

The dual powered 20-wheel dump truck labelled Rexx, has helped shift thousands of tonnes of waste material out of the Wallaby pit to a stockpile 15 kilometres away.

Rexx has completed round trips of 30 kilometres from the pit to the stockpile location, with over four times the distance capability of competing dump trucks and an on-demand power system that lowers fuel consumption.

This 'grunt work' follows extensive testing at Glencore’s Murrin Murrin mine in WA, where Rexx delivered up to 30 per cent reduction in operating costs compared with conventional dump trucks.

"Rexx is performing extremely well at the mine, proving its ability to come out of the Wallaby pit with a 160 tonne payload," Bis chief executive Brad Rogers said.

"As part of the testing during the trial, Rexx has also completed numerous hill starts fully loaded, on the incline."

The truck has also operated fully loaded in pits below the water table and handled the sticky and boggy conditions with ease.

Rexx also has the capacity to carry enough fuel for at least two 12-hour shifts, eliminating downtime needed for refuelling.

"We are embracing innovation and technology across our mining operations and this is a great example of how we can work with our business partners to create advances in the industry," Granny Smith general manager Andrew Bywater said.

"We see this as a real opportunity to explore potential improvements in trucking efficiency, and are encouraged by what we have seen to date."
