The haul truck has been designed for flexibility and efficiency, the company said, and offers the ability to travel more than four times further than conventional dump trucks.

Rexx, designed in-house at the company's Perth facility, is the newest addition to its line of bespoke load and haul solutions; also included in that line-up are its Dual Powered Road Trains. According to CEO Brad Rogers, it brings together the best elements of both long-haul road trains and short-haul mine trucks.

"Rexx's robust and simple design leverages our existing knowledge and resources," he said. "This has meant we were able to keep our manufacturing costs low, allowing Bis to deliver savings to customers through our service delivery model."

Rogers added that Rexx, which is ideal for operation on narrower, lower specification roads and features improved tyre management, can be used at a wide range of mining operations in Australia, as well as internationally. A Bis axle-steering system will also help with turning radius; the design reduces turning circles to just 13.5m, allowing Rexx to manoeuvre more easily in smaller spaces.

Each Rexx unit will have the highest safety requirements on-board and be equipped with Bis' fatigue management system, 360° view cameras and reversing cameras for greater hazard management.
